mixsoon Vitamin C 20 Serum — 20% Vitamin C Derivatives, Gentle 10ml Brightening Serum

mixsoon Vitamin C 20 Serum is a lightweight, dermatologist-tested 20% vitamin C derivative formula designed to brighten skin appearance and help even skin tone without sticky residue.

This concentrated 10 ml Korean glass-bottled serum blends stabilized vitamin C derivatives with supporting antioxidants to refresh dull-looking skin and improve overall radiance. The formulation prioritizes fast absorption and gentle performance so it layers easily under moisturizers and makeup. Clinically evaluated for tolerance, it’s aimed at users who want a potent vitamin C treatment but need a non-irritating, everyday-friendly product.

How will this serum fit into my morning or evening routine?

Use the serum after cleansing and toning, then follow with moisturizer and sunscreen in the morning or a nourishing cream at night. Its lightweight texture absorbs quickly, so it won’t interfere with multi-step regimens.

• Apply 2–3 drops to cleansed face and neck.
• Press gently until fully absorbed before layering other products.
• Use once daily at first, then increase to twice daily if tolerated.

What active ingredients make this effective and gentle?

The formula centers on stabilized vitamin C derivatives at a 20 concentration level, combined with niacinamide and glutathione to support brighter-looking, smoother skin. These complementary antioxidants help reduce the appearance of uneven tone while maintaining a gentle profile suited for sensitive skin in clinical testing.

• High-purity vitamin C derivatives for sustained brightening effect.
• Niacinamide to aid barrier support and refined texture.
• Glutathione for antioxidant balance and a more even appearance.

Will the serum feel heavy or leave residue on my skin?

No — the serum is formulated to be lightweight and non-sticky. It absorbs rapidly, providing a smooth base that works well under makeup or heavier creams without leaving a greasy film.

• Fast-absorbing, water-light texture.
• Non-greasy finish ideal for layering.
• Suitable under sunscreen and daily cosmetics.

Is this suitable for sensitive or reactive skin types?

Clinical testing indicates the formula is dermatologist-tested and gentle enough for many sensitive skin types; however, individual reactions can vary. Conduct a patch test before full-face use and introduce the serum gradually to monitor tolerance.

• Dermatologist-tested in clinical studies for gentleness.
• Start with limited application frequency to assess sensitivity.
• Discontinue use if irritation occurs and consult a professional.

Who is this for: mixsoon Vitamin C 20 Serum is built for people seeking a potent, fast-absorbing vitamin C treatment that supports brighter-looking, more even skin without heavy or sticky textures. It’s a good match for those with normal to sensitive skin who want clinical gentle performance, anyone layering multiple skincare steps, and users looking to add a targeted antioxidant boost to daily care. If you have highly reactive skin, consider patch testing first or consulting a dermatologist before regular use.
