ingredients and their purpose
pyrus malus (apple) fruit water: is water that has been distilled from apples. it vitalizes and nourishes the skin with naturally occurring vitamins and minerals. with a lower PH value than regular water, apple fruit water has a closer affinity to skin’s own PH balance, thereby enhancing the moisturizing and soothing properties. apple fruit water also stimulates the growth of keratin in the outer layers of the skin and therefore strengthens the skin’s ability to retain moisture and protect it from outside damage.
butylene glycol: is a chemically produced solvent which is hygroscopic. butylene glycol allows the skin the lock in moisture more sufficiently and it therefore appears more plumper and smoother.
glycolic acid: is a chemical peel which is used to improve the skin’s appearance and texture. it reduces wrinkles, acne scarring, hyperpigmentation and improves many other skin conditions. glycolic acid reacts with the upper layer of the skin and acts as a chemical exfoliator exposing live skin cells.
niacinamide: induces the production of ceramide and cholesterole – both of them are part of the horny layer (natural skin barrier) which is responsible for protecting the skin from drying out. it also reduces sebum production, is antiphlogistic/antibacterial and moisturizing.
sodium hydroxide: is used to stabilize the PH value to a skinfriendly level.
1,2-hexanediol: has moisturizing features
panthenol: is moisturizing, it enhances wound healing and prevents skin irritation by stimulating the energy metabolism and the ideal nourishment of the skin cell.
sodium hyaluronate: reduces irritations and protects the skin from pollution, it also keeps the skin from loosing all its natural moisture.
xanathan gum: moisturizes and protects the skin from dehydration.
ethyl hexanediol: is used as a solvent for manufacturing cosmetics
this is one of the few products which showed an immediate improvement in my skin. i was so surprised by the effect it had after having used it for only a couple of times. the regular use of the cosrx aha 7 whitehead power liquid allowed me to clear my skin from whiteheads and to control new ones from popping up. as it is quite a strong essence i only use it at night and make sure to generously moisturize my skin. to make sure my skin is protected during the day after having used the essence the night before, i apply sunscreen in the morning and use no further exfoliators. the cosrx aha 7 whitehead power liquid has truly become a holy grail in my night-time skincare routine and has totally changed the appearance of my skin.
