Best if you want to: Improve the appearance of blemish-damaged skin, control oiliness and moisturize while you sleep with a light, moisturizing, non-oily lotion that sinks into the skin. How it works: Lemon tea tree and Community Trade tea tree oil from Kenya contain properties that help fight blemishes and prevent new ones from forming. Tamanu oil from Madagascar has a soothing effect and helps to calm irritation and redness.
