This is the "CHAINON Eyelash Serum." * Developed jointly by a beauty clinic and a hair research institute, it contains carefully selected ingredients based on scientific evidence. * Contains ingredients such as Capixyl, WildLash, Redensyl, and SymLash, which give eyelashes firmness and body. * Does not contain ingredients that can cause pigmentation and is weakly acidic, so it can be used regardless of skin type. * It uses an ultra-fine brush that is easy to apply to the roots and edges of the eyelashes, and can be used like an eyeliner.
