Secret Key’s Starting Treatment Essence is modelled on the category pioneered by SK-II, leveraging Galactomyces ferment filtrate at high concentration, one of the most evidence-backed brightening and pore-refining ingredients in cosmetic dermatology. A K-beauty must-have for anyone seeking proven brightening and skin-smoothing results at an accessible price point.
An iconic fermentation-powered first essence featuring Galactomyces ferment filtrate as its hero ingredient to brighten, refine the appearance of pores and deliver a luminous, glass-skin texture with consistent use. A staple first essence step that prepares skin to absorb subsequent skincare more effectively, layering effortlessly into any Korean multi-step routine.
After cleansing, dispense a small amount into the hands or onto a cotton pad and gently pat into the skin.
