Skin-Nomad's Take — At a Glance

• 95% Centella Asiatica serum — minimal formula, maximum calming activity
• Repairs barrier damage and reduces redness with consistent use
• Suits all skin types; particularly effective for reactive and post-treatment skin

The Mary&May Centella Asiatica Serum is the brand's most deliberate minimalist formula: 95% Centella Asiatica Extract with nothing unnecessary added. Where other brands layer Centella alongside many supporting ingredients that dilute its concentration and complicate tolerability, this serum commits to the active at the highest practical dose — present at the level where its four triterpenoid compounds (Madecassoside, Asiaticoside, Asiatic Acid, and Madecassic Acid) function at full anti-inflammatory and barrier-repairing capacity rather than at the percentage that permits a Centella label claim. For reactive, barrier-damaged, or acutely sensitised skin dealing with redness, post-treatment irritation, or chronic fragility, the absence of additional ingredients is as important as the concentration of the active — every additional ingredient in a formula introduces a potential irritation variable that compromised skin does not need. Mary&May is a Seoul-based South Korean brand built on high-concentration actives and full EWG ingredient transparency.

Key Benefits

The formula delivers concentrated Centella Asiatica calming, barrier repair, collagen support, and deep hydration in a minimal, maximally-tolerated daily serum for reactive and barrier-compromised skin.

• Madecassoside for Anti-Inflammatory Calming and Wound Healing: Madecassoside inhibits inflammatory cytokine production and supports the skin's natural wound-healing response, visibly reducing redness and calming the sensitivity that accompanies barrier damage, active breakouts, and post-treatment recovery. At 95% Centella concentration, the Madecassoside content is at the highest practically achievable topical dose.
• Asiaticoside for Collagen Synthesis and Barrier Strengthening: Asiaticoside stimulates fibroblast activity to promote collagen and elastin production, improving skin resilience and structural integrity over consistent daily use. Its contribution makes this serum relevant for skin longevity maintenance as well as acute calming, supporting the long-term barrier strength that determines how reactive skin becomes in daily life.
• Asiatic Acid and Madecassic Acid for Antioxidant Cellular Protection: The two Centella triterpenoid acids provide complementary antioxidant activity that protects skin cells against UV-generated and environmental free radical damage, addressing the oxidative stressors that progressively sensitise and weaken the barrier with consistent daily exposure.
• Deep Hydration from Natural Centella Polysaccharides: Centella extract contains natural polysaccharides with strong humectant properties that deliver immediate surface hydration and support the skin's moisture retention capacity, providing visible plumping and comfort alongside the active calming and repair benefit.

Why Choose the Mary&May Centella Asiatica Serum?

• 95% Versus the Industry Norm of Under 10%: Most Centella serums use the ingredient at 5% to 10%, where its presence is meaningful but not at the level where all four triterpenoid compounds are delivering their full clinical activity. At 95%, this serum operates at a fundamentally different concentration tier — more comparable to a Centella treatment than a Centella-infused formula.
• Minimal Ingredient List for Maximum Tolerability: The minimal formulation removes every additional ingredient that could trigger sensitivity or allergic response in compromised skin. For acutely reactive, post-procedure, or chronically sensitised skin, a 95% single-active serum with a short, clean ingredient list is more appropriate than a multi-active formula where any component could be a sensitisation variable.
• EWG Green-Grade Verified: Free from parabens, artificial fragrance, alcohol, and mineral oil. All ingredients are EWG green-grade verified.

Ideal For

• Skin types: All skin types, particularly reactive, sensitive, rosacea-prone, acne-prone, barrier-compromised, and post-treatment skin
• Skin concerns: Redness, barrier damage, sensitivity, post-breakout recovery, post-procedure recovery, dehydration, and skin longevity maintenance
• Best used by: Those dealing with acutely sensitive or barrier-compromised skin who need the highest concentration of calming activity without the complication of additional actives, and anyone who has cycled through multiple multi-ingredient calming serums without the relief they expected.

FAQ

Q: How does 95% Centella compare to the 100% concentration in some specialist serums?
A: At 95% the formula contains Centella Asiatica Extract as the overwhelmingly dominant ingredient with 5% reserved for the base formulation necessities that make it a stable, deliverable serum. The active compound content is functionally equivalent to 100% Centella for skincare purposes. The distinction between 95% and 100% is more about formulation than meaningful activity difference.

Q: Can I use this as my entire routine during a sensitivity flare?
A: Yes. During acute sensitivity, barrier compromise, or post-procedure recovery, a simplified routine of cleanser, this serum, and SPF is often the most effective approach. The Centella's full activity is delivered at this concentration without the complexity of a multi-active routine that introduces additional variables to already-reactive skin.

Q: Can I layer this with other actives?
A: Yes. Apply this as the first serum after cleansing for its full calming benefit, then layer other actives on top on stable days. During retinoid or acid adjustment periods, applying this before and after the active ingredient effectively buffers the barrier against sensitivity at both ends of the exposure.

The Mary&May Centella Asiatica Serum is the formula for skin that has finally accepted that sometimes the most sophisticated skincare step is the one with the fewest ingredients.
