Salicylic Acid and Urea based exfoliating and hydrating leave-on night mask, for acne-prone, oily, sun-damaged or sensitive skin.

Salicylic acid exfoliates the skin and being a cousin of asprin, it has anti-inflammatory properties and can soothe the skin. When paired with Urea, a rich humectant, it softens, hydrates the skin and unclogs pores. It can be used as a leave on mask twice weekly or as a spot treatment on blemished or dehydrated skin.

Evidence: Salicylic Acid

Being related to Aspirin, Salicylic acid has anti-inflammatory properties and is generally well-tolerated. It exfoliates the skin and has been shown to be effective in reducing acne and helping to manage some of the signs of premature (sun-induced) skin aging (especially hyperpigmentation) and psoriasis.
