Dermalogica Boosters intensify attention to where your skin needs it daily, helping to cutomise your moisturiser for powerful results. Boosters are as much a part of your skincare regime as your cleanser and moisturiser are. They work well layered under your moisturiser, mixed with your moisturiser, layered underneath your skin masque or even mixed with your exfoliant. With just five to seven drops & an extra ten seconds a day, Dermalogica Boosters can help boost the power of your skin care regime.
