01 CLEANSER OR FACE SCRUB?

What’s the difference? Both can be used to wash your face, just in different ways. ‘Cleansers remove dirt, oil and make-up because they contain surfactants, which are soap-like molecules that trap impurities,’ says Dr Heather Woolery-lloyd, director of ethnic skincare for the University of Miami. While face scrubs can help cleanse, they don’t always remove stubborn make-up. Instead, they use tiny particles to physically exfoliate by lifting away dead skin cells. ‘Usually, scrubs are made up of physical ingredients that actually scrub away the dead skin to clear flakiness, stimulate blood flow and promote cell renewal,’ adds Dr Woolery-lloyd. ‘Ingredients in scrubs vary, but tend to include salt, sugar, microdermabrasion crystals or plant extracts. And the larger the pieces, the more aggressive the scrub.’ It means those with sensitive skin should exercise a bit more caution. Dr Dianni Dai, skin specialist at Pulse Light Clinic, warns against face scrubs that contain refined walnut shells or kernels. ‘These have rough edges and can cause micro tearing and scarring of the skin,’ she explains. She advises anyone with sensitive skin, as well as those prone to getting hypertrophic or keloid (raised) scars, to avoid physical face scrubs entirely. As for everyone else? ‘Gentle physical scrubbing every now and then can help speed up the shedding of dead skin cell layers.’

How to use them: Lather up with a cleanser morning and night – but pay attention to consistency. Go for creamy washes if you have sensitive skin and acid-based formulas if you’re oily. Face scrubs can be harsh, so use them no more than twice a week, and always with a gentle touch.
