Meghan Markle and Kate Hudson Love This Skincare Line — and InStyle Readers Get an Exclusive Discount

The business of beautifying celebrities is an art. Every time someone famous walks down the red carpet, if you listen closely, you can almost hear hundreds of PR people emailing the media to let them know which products they’re showcasing. It’s easy enough to see their gorgeous dress or necklace in question — but as for the skin care responsible for celebrities’ glowing faces, that precious intel is a lot harder to guess.

But for those keeping track of years of PR missives (us), Kate Somerville’s products are the safest bet. And for today and tomorrow only, you can score a 30 percent discount on the line that Meghan Markle, Kate Hudson, and Demi Moore can’t get enough of.

Markle’s track record with the brand dates back to her pre-royal days: She’s mentioned that her love for facials at Kate Somerville’s L.A. clinic spans years, and while she was in Toronto for Suits, she stuck with products like the brand’s Quench serum to “maintain that glow.” Yet Kate Somerville’s line first climbed to fame for its ExfoliKate Intensive Exfoliating Treatment, a gentle scrub that smooths out skin and minimizes pores in two minutes flat.

Of the treatment’s 1,158 five-star reviews on Kate Somerville’s site, one “lifetime sunbather” notes that even at 46 years old, she’s never gotten so many compliments on how good her skin looks. Multiple people write that the exfoliant is magic, with one saying they “can’t believe how much this has improved the look and texture of my face. I have tried EVERYTHING and this, by far, is the best product.”

In light of ExfoliKate’s success, a few years ago the brand broadened the range to include the ExfoliKate Cleanser Daily Foaming Wash. Five hundred thirty-six reviewers say, yeah, that was a good decision. Especially for those looking for reliable face-brightening action, you can’t go wrong with the cleanser. Reviewers write that it keeps their acne-prone skin from breaking out, and some saw a night-and-day difference after switching to it from cleansers that dried out their skin.

The cherry on top? Until December 4th, InStyle readers get 30 percent off and a free Retinol Vitamin C Moisturizer with the code CYBER30 when you spend $100. The moisturizer itself is usually $90, so this is an eye-bugging deal — especially for a cream that reviewers write is so powerful, “brown spots from thousands of beach days are fading.”

In the world of skin care, retinol and vitamin C are two of only a handful of ingredients that are actually proven to change skin. That potency makes for excellent results with this moisturizer, with a reviewer mentioning that for her older skin, it smoothed out fine lines within a month. Others second that it’s a game changer. “I started using this about a month ago,” one said. “Today, my boyfriend commented on how young I looked and asked what I did to my face. He said my skin looked and felt incredible.”

Does Prince Harry make similar comments? We can only think yes.
