The skincare world is watching K-Beauty’s latest shift: centella asiatica—known as cica in Korean skincare—and gel-based textures have become the dominant products for acne management in 2026. These ingredients and formulations aren’t just trend-driven marketing; they’re backed by growing clinical evidence and a global market that’s recognizing their dual benefit of treating acne while repairing the skin barrier. Mediheal’s Madecassoside Blemish Pads, for instance, represent exactly what’s trending: a concentrated active derived from centella that addresses both inflammation and barrier integrity in one product. The shift makes sense when you consider the acne problem itself.
Many acne treatments—particularly strong actives like benzoyl peroxide or isotretinoin—damage the skin barrier in the process of clearing breakouts, leading to dryness, sensitivity, and irritation that forces users to choose between clear skin and comfortable skin. K-Beauty brands have recognized this tension and engineered products specifically designed to treat acne while actively repairing the barrier, a distinction that separates these products from Western acne routines that often prioritize clearing at any cost. The global K-beauty market, currently valued at $14.68 billion in 2024, is projected to grow to $31.8 billion by 2033, with the U.S. segment expanding at 14.1% annually and potentially reaching $18.8 billion. This growth isn’t distributed evenly—barrier repair and anti-inflammatory actives are outpacing other categories, signaling that consumers are actively seeking exactly what these centella-forward and gel-based products deliver.

Why Are Centella and Madecassoside Suddenly Everywhere in Korean Acne Products?
Centella asiatica has been used in traditional medicine for centuries, but what’s changed is the isolation and concentration of its most bioactive compound: madecassoside. K-Beauty brands in 2026 are specifically formulating around madecassoside because it delivers measurable anti-acne effects that go beyond soothing redness. In clinical research, madecassoside has been shown to significantly inhibit pro-inflammatory cytokine IL-1β and reduce nuclear translocation of NF-κB in P. acnes-stimulated human cells—meaning it’s directly interfering with the inflammatory cascade that causes acne to develop in the first place, not just treating the symptom after it appears. The ingredient’s popularity reflects a broader shift in K-Beauty philosophy that prioritizes what Korean skincare calls “barrier-functional” formulations. Rather than separating acne treatment (actives) from barrier repair (moisturizers), brands are embedding barrier-repair ingredients into their acne products.
This approach has gained traction precisely because centella extract reduces acne-related inflammation: a four-week clinical study on 25 volunteers found that 5% Centella asiatica extract applied twice daily showed significant anti-inflammatory properties, and in lab studies with acne-causing bacteria, it reduced secretion of IL-1β, a major driver of the acne inflammatory response. One important limitation: centella asiatica extract and madecassoside are not acne treatments in the way that salicylic acid or retinoids are. They don’t exfoliate, don’t unclog pores directly, and don’t kill bacteria. They work upstream, in the inflammatory system. This means they’re most effective when combined with other acne-fighting ingredients or when treating inflammatory acne rather than comedonal acne. A product containing only centella will help calm existing breakouts and strengthen barrier function, but won’t necessarily prevent new breakouts on its own.
How Madecassoside Works Against Acne: The Science Behind K-Beauty’s Barrier Repair Approach
The mechanism of action that makes madecassoside appealing to acne sufferers is its dual role: it suppresses the inflammatory response that makes acne visible and uncomfortable, while simultaneously supporting the skin barrier’s structural integrity. When P. acnes bacteria colonize a pore, they trigger immune cells to release IL-1β and other pro-inflammatory cytokines. This cytokine cascade is what creates the redness, swelling, and pain of a pustule. Madecassoside interrupts this process by reducing IL-1β secretion and blocking NF-κB, a transcription factor that amplifies inflammatory signaling. The result is that inflammation subsides faster and with less collateral damage to the surrounding skin.
Where madecassoside becomes particularly valuable in acne treatment is when it’s combined with other acne-fighting actives. A 2024 clinical validation study found that madecassoside combined with cryptotanshinone—an active compound from Salvia miltiorrhiza—achieved a 94% reduction in follicular hyperkeratosis, compared with only 39% for cryptotanshinone alone. This synergistic effect is significant: it suggests that adding a barrier-repair ingredient to an acne active doesn’t dilute the acne-fighting benefit; it amplifies it. The theory is that by reducing inflammation alongside the primary acne mechanism, the skin can tolerate and respond better to the acne treatment itself. However, there’s a critical caveat: study results don’t always translate to real-world performance, particularly in acne treatment. The 2024 madecassoside + cryptotanshinone study involved a specific concentration and formulation, and different products will perform differently depending on how much madecassoside is actually included, what the pH is, what other ingredients are present, and individual skin factors. Additionally, the follow-up time in these studies is typically short—weeks, not months—so long-term efficacy and whether the effect holds after continuous use remains less documented.
Gel Creams and Gel Textures: Why Korean Beauty Is Moving Away from Heavy Moisturizers
K-Beauty’s shift toward gel-based acne products reflects a fundamental mismatch between traditional moisturizers and acne-prone skin. Acne-prone skin is often already lipid-rich and prone to occlusion; adding a heavy cream can exacerbate breakouts by trapping bacteria and sebum in pores. Gel textures—whether gel creams, gel serums, or gel moisturizers—deliver hydration and actives through a water-based matrix that feels lightweight on skin and doesn’t encourage occlusion. The texture is particularly important because acne-prone skin users are more likely to actually use a hydrating product consistently if it doesn’t feel greasy or suffocating. A 21-day clinical study on salicylic acid–containing gels demonstrated exactly why texture matters in acne treatment.
The study showed that salicylic acid gels significantly reduced acne while actually improving skin barrier function and hydration—sebum levels decreased by 23.65% after 21 days, Investigator’s Global Assessment improved by 23.81%, and only 5% of participants reported mild transient itching. This is remarkable because typical acne treatments cause dryness and irritation; a product that clears acne while strengthening barrier function represents a genuine advancement. The gel format was essential: the same active in a traditional cream formulation likely would have caused more irritation and less barrier improvement. Gel textures aren’t universally better than creams—they’re better for acne-prone skin specifically. Someone with very dry, sensitive, non-acneic skin may find a gel texture too light and ineffective as a moisturizer. But for oily and acne-prone skin, gel moisturizers and gel creams are now recommended as the first choice by skincare professionals and brands alike, precisely because they provide hydration and barrier support without increasing breakout risk.
The Clinical Evidence: Real Results from K-Beauty Acne Studies
Clinical data on K-Beauty acne products has expanded significantly, and the results are specific enough to be useful. Beyond the salicylic acid gel study mentioned above, a 2025 prebiotic gel cream study found measurable reductions in acne lesions through a different mechanism—supporting the skin’s natural microbiome rather than killing bacteria or reducing sebum. While the exact reduction percentage wasn’t detailed in the available literature, the finding that a gel cream can improve acne by modifying the microbiome represents an alternative pathway that complements traditional acne treatments. The Cica extract data is particularly striking for anyone concerned about acne scars and pore size. A 2025 clinical study on healthy Korean adults using a Cica-EV ampoule for just 15 days found: pore area decreased by 17.9%, pore density decreased by 26.9%, and wrinkle depth decreased by 7.8–18.8%.
While this study didn’t focus specifically on acne, the pore reduction is directly relevant to acne sufferers because clogged pores and enlarged pores are key features of acne-prone skin. The speed of these results—meaningful change in two weeks—suggests that cica actives work quickly on structural skin issues, not just inflammation. These studies share a common limitation: they’re typically conducted on smaller populations, over short timeframes, and often by the companies with commercial interest in the product. A 21-day study doesn’t tell you what happens at six months or a year. A 25-person study provides a signal, but not definitive proof. What these studies do establish is that the ingredients and formulations have measurable effects, and that acne improvement is reproducible under controlled conditions—which is more than can be said for many skincare claims.
Choosing Between Centella Products: Understanding Centella Extract, Madecassoside, and Cica-EV
Not all centella products are formulated the same way, and understanding the differences matters if you’re trying to solve a specific acne problem. Centella asiatica extract is the whole plant material, typically standardized to a certain percentage—the clinical studies referenced earlier used 5% concentrations. This form is gentler and includes multiple compounds beyond madecassoside, which some skin types tolerate better. Madecassoside is an isolated, purified compound, which means it’s more potent per dose and more predictable, but also potentially more irritating to very sensitive skin. Cica-EV appears to be a specific proprietary extract form, likely optimized for stability and absorption. The practical consequence is that a product labeled “Centella asiatica extract” might be gentler and slower-acting than one specifically featuring madecassoside at a high percentage.
If you have reactive, irritated acne-prone skin, starting with an extract-based product (like many K-Beauty essences and toners) makes sense before moving to a madecassoside-heavy product. Conversely, if you want faster results and your skin tolerates actives well, a higher-concentration madecassoside product will likely be more effective. One critical warning: the concentration of centella compounds matters far more than the presence of the ingredient. A moisturizer that lists centella as the last ingredient may contribute nothing meaningful to barrier repair or acne reduction, while a pads or serum with centella as the second or third ingredient will likely perform differently. Product concentration is rarely disclosed on labels, which means you may need to check brand websites, third-party ingredient databases, or rely on reviews from users with similar skin to yours. Additionally, if you’re using other actives—retinoids, salicylic acid, vitamin C—adding a centella product should be a supportive move, not a replacement for your primary treatment.
Trending K-Beauty Acne Products You’ll Actually Find in 2026
Mediheal Madecassoside Blemish Pads represent the category of K-Beauty acne innovation: a targeted, single-purpose product that delivers a specific active in a convenient format. The pads are pre-soaked in a solution concentrated with madecassoside, allowing for quick application and consistent dosing—you’re not trying to apply serum evenly or hoping you used enough. They work as both a treatment and an exfoliating step, since the pad itself provides gentle physical exfoliation while the madecassoside addresses inflammation and barrier function. Dr.G Red Blemish Clear with Eco-Cica is another trending product that exemplifies the barrier-repair approach.
This product specifically combines cica extract with a formulation designed for reactive, acne-prone skin, addressing both active breakouts and the sensitivity that often accompanies acne or acne treatment. Beauty of Joseon Glow Serum is noted as trending for acne-prone skin, suggesting that brands are positioning traditional K-Beauty ingredients (Joseon era skincare has historical roots) in modern acne-fighting formulations. The presence of these specific products in trending lists reflects consumer demand for products that feel innovative and effective without being harsh. Notably, none of these products are positioned as replacements for acne medications or prescription treatments; they’re positioned as complementary products that improve the overall experience of managing acne while reducing the barrier damage that often accompanies acne treatment itself.
Combining Ingredients: Synergistic Formulations and When Layering Works Best
The madecassoside and cryptotanshinone synergy study revealed something that challenges how many people approach acne treatment: combining ingredients can produce non-additive results. A 94% reduction in follicular hyperkeratosis when madecassoside is added to cryptotanshinone, compared with 39% for cryptotanshinone alone, isn’t just a 55-percentage-point improvement—it’s evidence that the two compounds work through complementary mechanisms and enhance each other’s efficacy. This finding has direct implications for how you layer K-Beauty acne products.
If you’re using a salicylic acid product to exfoliate and treat breakouts, adding a madecassoside-based product (like the Mediheal pads) may provide greater acne reduction than either product alone, because madecassoside addresses the inflammatory amplification that salicylic acid triggers. Similarly, combining a gel-based salicylic acid product with a centella-based essence or serum allows you to get both the direct acne benefit (exfoliation, pore-clearing) and the barrier-protective benefit (anti-inflammatory, barrier repair) without the typical tradeoff of dryness and damage. The key is using these as complementary layers, not as redundant products—two salicylic acid products won’t outperform one, but a salicylic acid product plus a madecassoside product likely will.
Frequently Asked Questions
Is madecassoside the same as cica or centella asiatica?
Madecassoside is an isolated compound derived from centella asiatica (also called cica). Centella asiatica extract contains madecassoside plus other active compounds. Products may use any of these forms—the isolated compound is typically more potent, while the extract is gentler.
Can centella products replace my acne medication or prescription treatment?
No. Centella and cica products are barrier-repair and anti-inflammatory products, not primary acne treatments. They work best as complementary products alongside salicylic acid, benzoyl peroxide, or prescription actives. They reduce irritation and barrier damage, but don’t directly address bacterial colonization or sebum production the way primary acne treatments do.
Why are gel textures better for acne than creams?
Gel textures are water-based and lightweight, so they hydrate without occlusion—trapping bacteria and sebum in pores. Clinical studies show gel acne products can reduce breakouts while actually improving barrier function, whereas traditional creams on acne-prone skin often worsen congestion.
How long does it take to see results from centella or cica products?
Clinical studies show measurable anti-inflammatory effects within 2-4 weeks, with pore and structural improvements visible within 15 days. However, acne improvement depends on whether centella is your only treatment or is combined with primary acne actives, and individual response varies significantly.
Can I use centella products if I’m on isotretinoin or another strong acne medication?
Yes—centella products are often recommended during retinoid or isotretinoin treatment specifically because they support barrier repair while the medication is working. However, check with your dermatologist before adding any new products, as some formulations may interact with prescription treatments.
