If you're looking to combat dark patches or uneven skin tone then you need to invest in this product. Environ Derma-Lac Lotion (£46) is so concentrated you need to either add it to a body oil or use a body oil straight after. It contains lactic acid which exfoliates any dry, stubborn areas of skin, and it can help treat certain skin conditions like Keratosis Pilaris, or chicken skin, and scarring.
