Hair's the Scoop

Keep your skin looking its best with celebrity esthetician Kate Somerville's seasonal survival guide:

1. Always wear sunscreen, and don’t forget to apply to your chest! There are fewer skin cells per inch on your neck and chest, so they tend to be thinner and more prone to aging and damage. Just like your face, they must be protected.

2. If you suffer from heat rash, cooling the body down is really important. Take a cool bath and pat (don’t rub) dry afterwards – and use a lotion without heavy oils in it.

3. Stay out of the real sun and use a self-tanner (like my 360º Tanning Towelettes) to achieve a gorgeous glow without the damage.

4. Keep your skin hydrated by following these three steps: exfoliate to slough dead skin cells off, hydrate your skin with water and steam, and lock it in with a good moisturizer. This external hydration must be complemented with internal hydration. Make sure to drink lots of water throughout the day!

"I'm a California girl. I used to be a sun worshipper. Now I'm trying to reverse the damage. I wear sunscreen, SPF15 on my lips and I reapply La Mer eye cream as often as I remember. I've got to make up for lost time."
