  • ACIDIFIER Tends to maintain or to regulate the naturally acid skin pH which can become timthumbunbalanced due to micro-bacterial aggression, sun exposure, diet…
  • ACTIVATES THE CELL RENEWAL Improves the exchanges by providing nutritive elements to stimulate cell metabolism.
  • AHA (FRUIT ACIDS) Alpha-hydroxyl-acids : found in most fruits. They act on cell cohesion. Low concentrations are excellent moisturizers. The higher their concentration, when placed in an acid medium, the higher their exfoliating power. For maximum efficiency and gentleness, YON-KA has carefully selected and exactly dosed:
    • glycolic acid (sugar cane, pineapple)
    • lactic acid (cranberry, maple, passion fruit)
    • tartaric acid (grape, citrus)
    • citric acid (orange, lemon)

    These AHA are known in cosmetology to help:

    • the faster elimination of dead cells,
    • the activation of cell renewal,
    • the improvement of the complexion and the reduction of wrinkles, spots, dry and dull skin, the gentle effect due to their moisturizing properties.
  • ALGAE Refer to Marine extracts.
  • ANALGESIC Pain relief.
  • ANTI-DESQUAMATION Avoids the excess elimination of epidermis cells.
  • ANTI-FREE RADICAL Neutralizes free radicals or prevents their appearance.
  • ANTI-INFLAMMATORY Prevents the appearance of redness, warmness, pain or swelling due to a traumatic skin aggression.
  • ANTISEPTIC Destroys microbes and prevents their development.
  • AROMATHERAPY Science of the use of aromatic oils or essential oils for therapeutic purposes.
  • AROMATIC OIL It is used in “aromatherapy”. Also called essential oil, the aromatic oil is the volatile and fragrant part of the plant. Aromatic oils quickly penetrate the body, both through the skin and the respiratory tract.

  • ESSENTIAL OIL It is used in a science called “aromatherapy”. Also called aromatic oil, the essential oil is the volatile and fragrant part of the plant. Essential oils quickly penetrate the body, both through the skin (skin action) and the respiratory tract (psychotropic action).

letter_f
  • FILTERING Absorbing UV rays by limiting their skin penetration.
  • FIRMING Can act on two levels :
    • superficial : lifting effect by contracting the proteic fibers,
    • deep : thanks to the essential oils, by stimulation of the skin blood circulation and the improvement in tissue nutrition.
  • FREE RADICALS They are unstable molecules produced by the organism. Under the effect of certain factors (pollution, poor diet, smoking…), the free radicals become true poisons that destroy some of our cells. They contribute to skin ageing.
  • FRUIT ACIDS (AHA) Alpha-hydroxyl-acids : found in most fruits. They act on cell cohesion. Low concentrations are excellent moisturizers. The higher their concentration, when placed in an acid medium, the higher their exfoliating power. For maximum efficiency and gentleness, YON-KA has carefully selected and exactly dosed:
    • glycolic acid (sugar cane, pineapple)
    • lactic acid (cranberry, maple, passion fruit)
