It’s time to kick-off the official start of summer with a few skincare tips from Christine Chin, esthetician to the celebrities and supermodels like Hilary Swank, Gisele Bundchen and Ellen Pompeo. Dubbed “Mean Christine” in the world of skincare for her extremely thorough work and brutal honesty, Christine is an incredible wealth of knowledge and has unparalleled attention to detail. To achieve beautiful and blemish free skin, follow these top three tips from Christine and take on the challenge of having perfect skin all summer long!

1. Make sure you’re washing your face up to your hairline, especially if you’re not washing your hair daily. Hair products like dry shampoo or silicone-based anti-frizz products can clog pores along your hairline.

2. Change your pillowcase regularly (at least 1-2 times a week). Your face is essentially resting on a bed of hair product and sweat and other bacteria overnight. If you’re low on pillowcases, take an unused tee shirt and put it over the pillow.

3. Toner HAS to be a part of your skincare routine. It removes any residue or grime that your cleanser misses and is essential for those with oily or acne prone skin.
