The Super Stable C Face Serum from MERME Berlin is a lightweight, water-based vitamin C serum designed to make skin appear fresher, clearer, and more even.
The minimalist formula combines three stable forms of vitamin C at a total concentration of 15% with 1% ferulic acid – for antioxidant care, increased radiance, and a refined skin texture. The precisely formulated serum fits perfectly into your morning skincare routine: light, non-greasy, fragrance-free, and suitable for sensitive skin.
- For pigmentation spots & dull skin: Helps make the complexion visibly more even and radiant and combats early signs of skin aging.
- 15% Triple Vitamin C: Three stable forms of vitamin C promote radiance, evenness, and a fresher-looking complexion.
- 1% Ferulic Acid: An antioxidant ingredient that protects the skin from oxidative stress and works complementarily with vitamin C.
- Light, water-based texture: Absorbs pleasantly and can be easily worn under moisturizer and sunscreen.
- Minimalist INCI list: Only 11 carefully selected ingredients – without fragrances and unnecessary additives – dermatologically tested.
- Clinically tested: In an independent 4-week study with 10 participants, improvements in hyperpigmentation, wrinkle depth, and skin firmness were measured – alongside stability and skin compatibility.
Vitamin C is one of the most proven active ingredients to counteract loss of elasticity, age spots, and dull skin. MERME does not rely on classic ascorbic acid but on three stable, skin-friendly vitamin C derivatives that complement each other in their effects: 3-O-Ethyl Ascorbic Acid acts quickly and specifically on radiance and skin tone, Ascorbyl Glucoside gently supports skin brightness, and Sodium Ascorbyl Phosphate completes the formula with antioxidant care and helps promote a clearer, more even complexion.
- Suitable for all skin types, especially dull skin, uneven skin tone, and pigmentation spots
- Promotes a more radiant, clearer, and firmer-looking complexion
- Water-based, lightweight texture with few ingredients
- Vegan, cruelty-free, and fragrance-free – dermatologically tested
MERME Berlin stands for minimalist skincare with clear active ingredient logic.

FAQ
When should I use the Super Stable C Face Serum?
The serum is applied in the morning after cleansing and before moisturizer. Always follow with broad-spectrum sunscreen.
Can I use the serum daily?
Yes, the serum is suitable for daily use. Sensitive skin can increase usage gradually, for example, every other morning at first.
Can I combine the vitamin C serum with retinal?
Yes, preferably in separate routines: vitamin C in the morning, retinal in the evening. This way, the skin receives antioxidant care during the day and regenerative active ingredient care at night.
Is the serum suitable for sensitive skin?
Yes, the formula is fragrance-free, dermatologically tested, and marketed for sensitive skin. For very reactive skin, a slow introduction is still recommended.
Does the serum help with pigmentation spots?
The vitamin C forms help make skin tone appear more even and reduce the appearance of hyperpigmentation. Consistent sun protection is crucial to prevent pigmentation spots from worsening.
Active Ingredients
- Vitamin C is a very powerful antioxidant involved in various enzymatic processes. Among other things, it promotes collagen synthesis, acts as a radical scavenger, and protects the skin from oxidative stress. Vitamin C balances skin tone and promotes an even and radiant complexion. Vitamin C can reduce sun damage and pigmentation spots and combat inflammation and skin irritation.
- 3-O-Ethyl Ascorbic Acid 13%: A stable form of vitamin C that improves skin radiance, evens skin tone, and can reduce the appearance of pigmentation spots.
- Ascorbyl Glucoside 1%: A gentle vitamin C derivative that gradually makes skin look fresher and is especially suitable for sensitive skin.
- Sodium Ascorbyl Phosphate 1%: A stable form of vitamin C with antioxidant properties that supports a clear, even complexion.
- Ferulic Acid 1%: A strong antioxidant that can neutralize free radicals and contributes to the stability and enhancement of the vitamin C formulation. Ferulic acid naturally occurs in plants and fruits, where it acts as a protective, self-preserving element.
