Retinol is a Vitamin A derivative that can help to reduce the appearance of fine lines and uneven skin tone while boosting collagen. Some traditional Retinols are too powerful to be used regularly, or on sensitive skin, and can cause irritation, redness & peeling. Bio-Retinols are plant compounds taken from plants such as bakuchiol, sea buckthorn oil, rosehip oil and carrot oil. Bio-Retinols are also high in Vitamin A/retinoids but are more gentle on the skin - giving similar skincare benefits to traditional retinol but without the common side-effects.
