Theramid: A Breakdown of the Spanish Brand's Products and How to Choose the Right Serum for Your Needs ^{Advertisement}

Today’s active skincare market is flooded with terms like “retinol,” “peptides,” “azelaic acid,” and “vitamin C,” but these identical names often hide completely different formulas, concentrations, and expectations for results. That’s exactly why two serums with the exact same active ingredient can behave differently on the skin: one noticeably evens out skin tone, while the other irritates the skin or has no effect at all. Theramid stands out because it builds its skincare approach not around general promises, but around specific active ingredients in clearly defined concentrations. This makes the brand stand out for those who have already moved beyond basic skincare and want to address pigmentation, breakouts, dullness, wrinkles, or a compromised skin barrier in a more targeted way.

At the same time, active skincare doesn’t follow the “the stronger, the better” principle. High concentrations can deliver faster and more pronounced results, but they require proper application, regular use of SPF, and an understanding of which ingredients should be combined and which are best used on different days. Theramid can serve as an alternative to overly mild mass-market formulas, but it does not replace a consultation with a dermatologist. If you have moderate to severe acne, persistent hyperpigmentation, rosacea, dermatitis, or reactive skin, it’s best to consult a specialist when selecting active ingredients. In this article, we’ll break down the ingredients that make up the line, how they work, and which product makes the most sense for your specific needs.

What Is Theramid and How Does the Brand Differ from Conventional Skincare?

Theramid is a Spanish brand of active facial skincare that focuses primarily on serums and cream serums with high concentrations of active ingredients. The brand’s approach is simple: instead of vague claims like “for radiance,” “against imperfections,” or “for youthful skin,” customers see specific active ingredients and their role in skincare. This is convenient for people who don’t just want to buy another serum, but rather build a clear skincare regimen: one product for hyperpigmentation, another for the skin barrier, and a third for preventing signs of aging.

In terms of its concept, Theramid falls between drugstore cosmetics and professional active skincare. It’s not a basic “everyday for everyone” cream, but neither is it an aggressive at-home peel that’s hard to control. The brand addresses various skin needs through specific formulas: azelaic acid targets breakouts and uneven skin tone; vitamin C tackles dullness and provides antioxidant protection; retinoids address skin texture and wrinkles; ceramides address barrier repair, and peptides support skin firmness.

This is the main advantage of the line: you can combine products, but you don’t have to buy everything at once. On the contrary, a gradual approach works best with active skincare: identify the main problem, introduce one active ingredient, assess the skin’s reaction, and only then add the next one. You can conveniently browse the full Theramid lineup at the Lullaby store via this link: there, you can compare formulas and concentrations and choose a product based not on a fancy name, but on your skin’s actual needs.

What active ingredients form the basis of the Theramid line

The Theramid line features several key groups of active ingredients, each with its own specific purpose. Azelaic acid in Azid Azelaic Acid 15% targets uneven skin tone, post-acne marks, breakouts, and redness. Vitamin C in C-Tetra E.F. addresses dullness, a tired complexion, and helps prevent photoaging. The retinoid formulas A-Retinoate and Clinical Vitamin A are used to address skin texture, wrinkles, loss of firmness, and skin renewal. The peptide products Derma-Peptides and Copper Peptide 3% support skin density, firmness, and regeneration.

Formulas for the skin barrier play a special role. Ceramide Treatment is needed when the skin has become dry, sensitive, tight, or has difficulty tolerating active ingredients. Smoothing Treatment improves skin texture through gentle exfoliation; Even-In is designed to address hyperpigmentation; and Lino-8 focuses on antioxidant support and nourishment. If your skin is complex or reactive, you should start not with the strongest active ingredient, but by assessing the skin barrier: sometimes ceramides and barrier repair provide a better starting point than acids or retinoids.

Why Concentration Isn’t the Only Measure of Effectiveness

When the packaging lists 15% of an active ingredient, it’s easy to assume that this number alone determines the product’s potency. In reality, concentration is important, but it doesn’t work in isolation from the formula. Effectiveness also depends on the form of the active ingredient, pH, stability, delivery system, supporting ingredients, and how well your skin tolerates the product.

For example, vitamin C can vary greatly. Pure ascorbic acid is active but unstable and often irritates sensitive skin. Lipophilic derivatives of vitamin C are generally gentler, blend better with the lipid barrier, and remain stable in the formula for longer. It’s the same story with retinoids: classic retinol, retinal, and retinoic acid have different rates of conversion and varying potential for irritation.

That’s exactly why it’s incorrect to compare skincare products based solely on percentages. It’s important to consider exactly which active ingredient is used, in what form, what it’s combined with, and whether it’s suitable for your skin’s current condition. Even the best serum may not work if it’s applied to a damaged skin barrier or if you start using it daily without a period of adaptation.

15% Azelaic Acid: Hyperpigmentation, Post-Acne, and Breakouts

Azelaic acid is one of the most interesting active ingredients for those who have several issues at once: uneven skin tone, post-acne, breakouts, redness, and clogged pores. It isn’t as harsh as classic exfoliating acids, but it still affects several skin mechanisms at once. First, azelaic acid helps reduce the appearance of pigmentation by influencing the activity of tyrosinase—an enzyme involved in melanin production. This is why it’s often used to treat post-acne and uneven skin tone.

Second, it helps normalize the exfoliation process within the pores. When skin cells shed unevenly, pores become clogged more easily, leading to closed comedones and inflammation. Azelaic acid is gentler than many AHAs, but it can be particularly beneficial for acne-prone skin. Third, it has anti-inflammatory properties, so it’s often better tolerated by people who can’t use harsh acids or overly aggressive acne treatments.

But it’s important not to idealize this ingredient. Even azelaic acid can cause a tingling sensation, dryness, or a mild burning sensation at first, especially if the skin barrier is already compromised. Therefore, it’s best to introduce Azid Azelaic Acid 15% gradually: start by using it a few times a week in the evening, rather than daily from the very first day. If your skin reacts well, you can increase the frequency.

Pregnancy and breastfeeding deserve special mention. Azelaic acid is often considered one of the acceptable active ingredients during periods when retinoids are contraindicated. However, it’s still best to consult a doctor about the specific product, concentration, and application regimen, especially if you have acne, melasma, or sensitive skin.

Vitamin C: Dullness, Antioxidant Protection, and a Healthy Glow

Vitamin C is most often sought after in skincare by those who want to reduce dullness, even out skin tone, and restore a fresh appearance to the face. C-Tetra E.F. uses a lipophilic—that is, fat-soluble—form of vitamin C. Its advantage is that it interacts better with the skin’s lipid environment, is generally better tolerated, and is more stable in the formula than classic ascorbic acid.

Vitamin C acts as an antioxidant: it helps neutralize free radicals formed by exposure to UV rays, air pollution, stress, and other external factors. This is precisely why it’s often recommended for morning skincare. But there’s an important caveat: vitamin C is not a substitute for SPF. Sunscreen reduces the effects of UV rays, while antioxidants help the skin better cope with the effects of oxidative stress. Together, they work more effectively than they do separately.

C-Tetra E.F. is ideal for skin that looks tired, dull, uneven, has lost its natural radiance, or needs protection against early signs of aging. However, if the main issue is severe breakouts or persistent post-acne marks, it’s best not to use vitamin C as the sole active ingredient; instead, combine it with more targeted treatments, such as azelaic acid or formulas designed to address hyperpigmentation.

Retinoids and Vitamin A: Texture, Wrinkles, and Renewal

Retinoids remain one of the most powerful groups of active ingredients in at-home skincare when it comes to skin texture, wrinkles, loss of firmness, uneven skin texture, and the prevention of age-related changes. In the Theramid line, A-Retinoate and Clinical Vitamin A fulfill this role. They are chosen not for an instant glow, but for their gradual effect on skin structure.

Classic retinol must undergo several stages of conversion before becoming a biologically active form. Retinoates have a shorter pathway of action, so they can produce noticeable results with a lower risk of typical irritation, although dryness or an adjustment period cannot be completely ruled out. For many, this is a more comfortable way to get started with retinoids, especially if classic retinol has previously caused severe flaking.

It’s best to introduce retinoids in the evening, gradually and without rushing. A common mistake is to start using the product daily while continuing to use acids, scrubs, and deep cleansers, and then conclude that the product “didn’t work.” In reality, the problem is often not the retinoid itself, but an overloaded skincare routine. To start, two or three evenings a week is enough. If your skin is calm, you can increase the frequency.

Important note: Do not use retinoids during pregnancy or while breastfeeding without consulting a doctor. They also require daily SPF, even if the product is applied only in the evening. While using retinoids, your skin becomes more sensitive to the sun, and without protection, you may end up with new pigmentation rather than rejuvenation.

Peptides and Copper Peptides: Supporting Firmness and Regeneration

Peptides are not fast-acting ingredients like acids or retinoids. They work more gently but can be beneficial in skincare regimens designed to maintain skin elasticity, firmness, and overall health. It makes sense to view Derma-Peptides and Copper Peptide 3% not as a replacement for retinoids, but as a separate skincare approach for skin that needs regeneration, firmness, and a more well-groomed appearance.

Copper peptides are often of interest to those who want to combine anti-aging care with support for skin renewal. They don’t provide an instant lifting effect overnight, but they fit well into a long-term skincare regimen. They can be used during periods when the skin is tired, reacts to active ingredients with dryness, or requires a gentler approach than retinoids and acids.

However, the logic behind combining peptides is also important. Don’t apply all active ingredients in one evening just because each one is beneficial on its own. If your routine already includes a retinoid, an acid, and vitamin C, it’s best to use a peptide product on days or at times of day when your skin isn’t overloaded.

Ceramides: Why the Skin Barrier Is More Important Than It Seems

People often start their skincare routine by asking, “What should I use for hyperpigmentation?” or “Which serum is the most effective against wrinkles?” But it’s better to start with a different question: Can your skin handle these active ingredients right now? If you experience tightness, a burning sensation after washing your face, flaking, a reaction to your usual products, or a constant feeling of dryness, the problem may not be a lack of active ingredients, but a damaged skin barrier.

In this regimen, Ceramide Treatment plays a strategic role, not a cosmetic one. Ceramides help maintain the skin’s lipid barrier, reduce moisture loss, and make the skin less reactive. This is especially important for those who already use retinoids, acids, or anti-pigmentation products. Without a healthy barrier, active ingredients are more likely to cause irritation, and the results become unpredictable.

Sometimes the best approach isn’t to add another potent serum, but to simplify your routine for two to three weeks, sticking to gentle cleansing, ceramides, moisturizer, and SPF. Once the skin has calmed down, you can reintroduce active ingredients, but do so gradually. This approach may seem slower, but in the long run, it often yields better results.

How to Choose a Theramid Serum That Suits Your Needs

The easiest way to avoid making a mistake is to first identify your main goal. Don’t think “I want everything at once”—instead, focus on the one priority issue that’s bothering you the most right now.

If your main concern is post-acne marks, uneven skin tone, occasional breakouts, or a tendency toward clogged pores, Azid Azelaic Acid 15% is a logical place to start. If pigmentation is your top concern, you should also consider Even-In, but don’t forget that without regular SPF, any spot-correcting product will be less effective.

If your skin looks dull, tired, or ashy, but there’s no obvious inflammation, C-Tetra E.F. is a good choice. It’s a great morning treatment for those who want to add radiance and antioxidant protection. If your main concern is wrinkles, loss of firmness, rough texture, or uneven skin tone, consider A-Retinoate or Clinical Vitamin A.

If your skin is dry, sensitive, tight, or doesn’t tolerate active ingredients well, it’s better to start with Ceramide Treatment rather than retinoids or acids. If you want to support skin density, firmness, and regeneration, you can add Derma-Peptides or Copper Peptide 3% to your routine.

The Travel-size Discovery Set can be a convenient way to get acquainted with the textures and formulas. Miniatures don’t always let you assess the full effect of an active ingredient—since that takes time—but they help you determine whether the texture feels comfortable, if there’s any immediate adverse reaction, and if the product is suitable for your daily routine.

How to Introduce Active Ingredients Without Damaging the Skin Barrier

The results of active skincare often depend not only on which product you choose, but also on how you incorporate it into your routine. The safest rule is to introduce one new active ingredient at a time. If you start using vitamin C, azelaic acid, and a retinoid all at once, it will be difficult to determine the exact cause if irritation occurs.

The optimal approach is as follows: start with one active ingredient, monitor your skin for two to three weeks, then introduce the next one. If your skin remains calm—with no severe burning, flaking, breakouts, or persistent redness—you can gradually expand your regimen. If a reaction occurs, don’t immediately try to “treat” it with yet another active ingredient. It’s better to simplify your routine and focus on restoring the skin barrier.

Mornings are usually reserved for antioxidants: vitamin C, moisturizer, and SPF. Evenings are for skin renewal: a retinoid or azelaic acid. Beginners should avoid combining a retinoid and azelaic acid on the same night until the skin has gotten used to each one separately. Ceramides and peptides usually fit more easily into most routines, but even with them, it’s best to monitor your skin’s reaction.

An example of a simple routine to start with

For skin with dullness, post-acne marks, and early signs of aging, you can start with a very simple routine. In the morning: gentle cleansing, C-Tetra E.F., moisturizer as needed, and SPF. In the evening: cleansing, Azid Azelaic Acid 15% every other day or a few times a week, followed by a cream or barrier-boosting product. Once your skin has adapted, you can gradually introduce A-Retinoate or Clinical Vitamin A on alternate evenings.

For sensitive or very dry skin, the routine should be different. Start with Ceramide Treatment, gentle cleansing, SPF, and a minimum of irritants. And only after the skin’s condition has stabilized—add one active ingredient to target the main problem. If you start with aggressive exfoliation on a damaged skin barrier, the risk of irritation will be significantly higher, and the results will be worse.

For skin prone to breakouts, you shouldn’t use all “anti-acne” products at the same time. Often, a single stable active ingredient—such as azelaic acid—works best, combined with gentle cleansing, non-comedogenic moisturization, and regular SPF. An excess of acids, alcohol-based lotions, and scrubs can only worsen irritation.

The Most Common Mistakes When Using Theramid and Other Active Ingredients

The first mistake is buying several strong serums at once and starting to use them simultaneously. This seems logical: if your skin has multiple issues, you want to address them all at once. But for the skin, this is often stressful, especially if it isn’t used to active ingredients.

The second mistake is expecting instant results. A glow from vitamin C or smoother skin from acids may appear more quickly, but pigmentation, post-acne marks, skin texture, and wrinkles take time to improve. You should realistically evaluate active skincare not after three days, but after at least 6–12 weeks of regular and proper use.

The third mistake is neglecting SPF. Any treatment for pigmentation without sun protection loses much of its effectiveness. Active ingredients may help even out skin tone, but UV rays will constantly trigger the appearance of new spots.

The fourth mistake is applying active ingredients to irritated skin. If you experience a burning sensation, cracks, severe flaking, or a reaction even to a basic moisturizer, this isn’t the best time to use retinoids or acids. Restore the skin barrier first, then apply active ingredients.

The fifth mistake is judging a product solely by its concentration. A high percentage of an active ingredient doesn’t guarantee better results if the formula is unstable or unsuitable for your specific skin type. Conversely, a milder but well-formulated serum can provide a more consistent and comfortable effect.

Who Will Benefit Most from Theramid

Theramid is primarily suited for those who already have a basic skincare routine and understand the importance of cleansing, moisturizing, and SPF. This brand isn’t meant for haphazard use, but for a well-thought-out skincare regimen. If you’re willing to introduce active ingredients gradually, monitor your skin’s reaction, and not expect instant results, this line can be very convenient.

The brand is also appealing to those who want to transition from gentle, all-purpose products to more targeted formulas but aren’t ready for complex professional regimens. Theramid allows you to tailor your skincare routine to a specific concern: hyperpigmentation, breakouts, dullness, wrinkles, the skin barrier, or skin firmness.

However, if your skin is highly reactive, you have an active dermatological condition, or you’ve experienced poor tolerance to most active ingredients, it’s best not to experiment on your own. In such cases, even a high-quality product can cause an adverse reaction if it’s improperly selected or applied.
