Kendall & Kylie Jenner's Skincare Secrets Revealed

We don't often get to see the Jenner sisters' makeup-free skin, but it's pretty clear that their complexions are well looked-after. As it turns out, though, Kendall and Kylie Jenner's skin care routines are actually pretty simple. The woman behind their flawless faces, Beverly Hills-based Certified Physician Assistant in dermatology Christie Kidd, dished on their routines in a video posted on Kylie's website.

Being a dermatologist to the stars is no easy task — with clients who wear heavy makeup on a daily basis and face a constant pressure to look perfect in front of cameras, keeping celebs' skin clean and clear can be challenging. Having famous clients with teenage skin, too? Kidd's got her work cut out for her.

Kendall has opened up about her skin care struggles before, revealing her acne problems from the past on her app in October. Kylie named Kidd as their family dermatologist in an interview with The New York Times, mentioning that she worked wonders on her sister's skin problems. So it sounds like Kidd is the one behind one of the modeling industry's freshest faces (literally.)

Although Kidd's approach is pared-down, she has some useful tidbits about layering products, mixing products, and tinted moisturizer (apparently it's pretty much the devil of skin care.) Here's what she had to say:

Here are Kidd's five cardinal skin care tips, along with the products Kylie has copped to using in her own routine.

"Less Is More"

Cetaphil Daily Facial Cleanser, $14, Amazon

"Less products in your bathroom is going to be so much better for your skin," advises Kidd. The products she talks about throughout the video are cleanser, sunblock, and moisturizer — and not much else. In 2011, Kylie named Cetaphil as her go-to cleanser to Celebuzz, and with a product that consistent, why switch it up?

"Start With Sunblock"

Tizo3 SPF 40, $27, Amazon

After cleansing your face well in the morning, reach for the sunscreen, says Kidd. This is wise advice that we've heard time and time again, but it's refreshing to hear that an 18-year-old star is taking it to heart. Kylie told The New York Times that she loves TiZO3's UV protection.

Avoid "All In One" Products

Mimosa Blossom Dream Cream, $19, Amazon

This is where we get into the tinted moisturizer shaming. "Tinted moisturizers are designed to absorb deep into the layers of your skin to hydrate your skin and protect it, but it's bringing all that pigment with it and that is going to break you out," says Kidd. Opt for a light pigment-free moisturizer in the morning instead — Kylie goes for Super Salve's Mimosa Blossom Dream Cream, according to the New York Times.

Apply Light To Heavy

Kiehl's Creamy Eye Treatment with Avocado, $29, Nordstrom

After removing your makeup at the end of the day and washing your face well, apply your go-to products strategically. Kidd recommends using your thinnest product first (like a serum), then a thicker moisturizer and eye cream around your eye (Kiehl’s avocado eye treatment is Kylie's pick, she told The New York Times.) "And don't forget your lip balm so your lips don't dry out while you're sleeping!" says Kidd.

Be Careful What You Mix

Use caution if there's an anti-acne product in your routine, because the acne-fighting elements could be doing more harm then good when they're paired with other harsh ingredients."Benzoyl peroxide is a good acne agent, but when mixed with other products that have acid in it, it can increase the irritation of where you apply the benzoyl peroxide," says Kidd. If your skin does get irritated, try one of Kylie's beloved Sephora masks in a soothing formula (she plays around with different ones, according to The New York Times.)
