What it is
[Limited Quantity] Achieve firm, supple skin with this undiluted retinol derivative. Now available in a generous 30mL size. Recommended for: Worried about signs of aging? Can't laugh out loud in the evenings? Dry, streaky skin around the eyes, cheeks, forehead, and mouth? Worried about lack of firmness around the neck? Key Points of Retinol: Total care for skin prone to signs of aging. Retinol is a type of vitamin A, often found in eye creams. It targets areas prone to aging, including the eyes, mouth, cheeks, and neck. Penetrates deep into the skin: Retinol, which is unstable, is converted into a derivative that easily penetrates the skin and then encapsulated. This double stabilization delivers retinol deep into the skin, plumping it up and improving elasticity. Because it's undiluted, the ingredients used in cosmetics are bottled in their original form. Because it contains no unnecessary ingredients, it reaches the skin directly. "Protective" retinol that can be used on sensitive skin: This product uses "retinol palmitate," which is gentle on the skin, to prevent retinoid reactions such as redness and peeling. Its "protective" formula does not cause strong irritation, so it can be used by those with sensitive skin.
Ingredients
How to use
