MASTER SWITCH

Having started with the 2% serum with no issues I was unsure about switching to this stronger option. I’ve experienced no adverse reactions which has happened in the past. My skin appears clearer & smother in a very short period of time. Fully recommend this.

Great Retinol

Master switch is a game changer in retinol products. It's powerful so don't use it every EVENING unless you are used to Retinol. After just two weeks, the surface of my skin is brighter, wrinkle are less. Always wear SPF daily while using this product.
