Abstract
A cosmetic product is disclosed in the form of a gelatin walled capsule encompassing a cosmetic composition that includes a carrier which is a silicone polymer and an antioxidant. The antioxidant operates to inhibit degradation of the gelatin wall to prevent malodors from being generated. Retinoic acid derivatives such as retinyl palmitate are especially effective as antioxidants.
