Description

Is your complexion looking dull, are pigmentation spots and fine lines becoming more noticeable and does your skin feel less firm? Yon-Ka Serum C20 from the Intensive collection is your powerful answer. This anti-aging serum contains 20% stabilised vitamin C in a formula with 99.9% natural ingredients and visibly transforms the skin: the complexion looks more even and radiant, wrinkles appear less deep and the skin feels firmer and more elastic. Suitable for all skin types, even the most sensitive skin.

How it works

The stabilised vitamin C (ascorbyl tetraisopalmitate) is oil-soluble and therefore stays stable; it helps to even out the complexion, fade pigmentation spots and protect against free radicals. Biotechnology-derived turmeric and pomegranate cells support firmness and elasticity. Organic apricot kernel oil nourishes and softens, while sweet orange oil and the signature Yon-Ka Quintessence complex (lavender, geranium, rosemary, cypress, thyme) create the recognisable aromatic experience.

Texture and use in your routine

The texture is light and oil-like, absorbs quickly and leaves no greasy film. Use the serum in the morning after Lotion Yon-Ka PS or PNG, alone or under your day cream such as Hydra N°1 Crème or Elastine Jour. For an intensive cure you can also apply it in the evening for 4 to 8 weeks. During the day, pair it with reliable sun protection such as Crème Solaire SPF 50. Avoid layering it in the same step with strongly exfoliating products.
