Brighten and firm your skin with potent 20% Vitamin C
Our powerful brightening face serum is infused with a potent, all-natural 20% Vitamin C stabilized for maximum efficacy and tolerability. Composed of 99.9% ingredients of natural origin, this dark spot serum features Ascorbyl Tetraisopalmitate, an all-natural, oil-soluble form of Vitamin C derived from green science. Our antioxidant face serum helps defend against environmental skin aging and supports the body’s collagen synthesis to help firm skin. Native turmeric and pomegranate cells help intensify the multi-corrective actions of the Vitamin C as they combine to help improve skin firmness and unify skin tone by minimizing the appearance of dark spots and illuminating the complexion. Apricot Kernel Oil, rich in phytosterols, helps moisturize and comfort skin.

❖ 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.

❖ Highly concentrated antioxidant treatment powered by a potent 20% concentration of stabilized Vitamin C.
❖ Each bottle contains 1.5 million fresh native pomegranate and turmeric cells, resulting in 25,000 cells per application.
❖ Unique waterless oleo-serum sustains the potency and efficacy of the Vitamin C without an oily feel.
❖ Infused with sweet orange and our proprietary Yon-ka Quintessence composed of five essential oils for healing and sensorial benefits.
