Dermalogica Solar Defense Booster If classic SPF formulas are hard for you to get behind, try mixing Dermalogica's Solar Defense Booster (£44) into your foundation or daily moisturiser. It's on the pricier side of the spectrum, but we promise that you'll get the UV-blocking benefits without even knowing it's there.
