Q: HOW OFTEN SHOULD I BE USING A SKIN SERUM? A:
Every day! There are serums to treat everything from pigmentation to dehydration to fine lines and wrinkles. But if you choose a multitasking serum targeting general skin health, you can use it morning and night. Apply it just after you cleanse, while skin is damp. Moisturise over the top to lock it in. Try Clarins Double Serum, $95.
