Yonka Serum C20 Vitamin C

❖ Formulated with 99.9% ingredients of natural origin
❖ Native Curcuma longa plant cells – a powerful antioxidant
❖ Known for its extraordinary antioxidant power, Curcuma longa in its “native cell” form improves skin tone and elasticity. It complements the protective, anti-wrinkle actions of vitamin C.
❖ Native pomegranate cells help the skin boost its radiance and even out the complexion. They bolster the radiance-boosting, anti-dark spot actions of vitamin C.
❖ By regulating tyrosinase, native plant cells reduce melanin synthesis by 15%.
❖ Obtained from organic apricots, the oil extracted from the kernel is high in vitamins A and E and phytosterols, giving it the ability to deliver a true radiance boost to skin and fight aging. It also contains high amounts of omegas 9 and 6, known for their nourishing, softening, suppleness-boosting properties.
❖ Yon-Ka Quintessence is the brand’s true DNA. This exclusive complex of 5 essential oils (lavender, geranium, rosemary, cypress, thyme) increases the power of the rest of the formula.

In the epidermis(*), native turmeric plant cells encourage epidermal cell renewal by increasing the proliferation of keratinocytes by 16%.
The following observations have been made in the dermis(*):
❖ + 17% increase in collagen and elastin fiber synthesis.
❖ + 20% increase in GAG synthesis, including hyaluronic acid.
