Skin Concern:


Key ingredients:

  1. Cellulose Gum

A natural ingredient that is widely used as a thickener and creates a protection layer to prevent moisture loss.

  1. Mineral Oil

Cosmetics-grade mineral oil which is perfectly safe and also non-sensitising. It is widely used as a skin replenishment and moisturiser. The mineral oil helps to seal in moisture and promote wound healing therefore preventing formation of hyperpigmentation or scarring. Mineral oil in skincare products is certified by either USP (United States Pharmacopeia) or BP (British Pharmacopeia), therefore it is completely harmless and beneficial to the skin.

  1. Polyurethane Film

A material commonly used to cover wounds while also speeding up the recovery phase.

Step 2: Apply on the area of concern

Librarian Tip: Put it on overnight so you don’t have to worry about it being visible to others
