Tune In: Celebrity Esthetician Shani Darden's Best Skin Care & Beauty Tips

I've had the pleasure of receiving a Shani Darden facial, and let me tell you: This woman is magic. The celebrity esthetician (whose clients include Jessica Alba, Rosie Huntington-Whiteley, and Shay Mitchell) has a refreshingly no-nonsense approach to skin care. I remember during my facial, she took the time to evaluate my skin, accurately noting how sensitive it was, and adjusted accordingly. There are no add-ons or special extras you need to pay up for: She just gives the skin what it needs. Each facial is specifically created for the client's skin, in that exact moment.

We also chatted throughout the facial, during which she took the time to educate me on what she was doing, why she was doing it, and what I should be doing at home. She's also the founder of her namesake skin care and facial tool device brand, Shani Darden Skin Care, so those who can't score a sought-after appointment at her Beverly Hills spa can get a taste of the treatments at home. 

I recently caught up with Darden on this week's episode of Clean Beauty School. Throughout the episode, we talk about her approach to skin care, her must-have products, and her favorite skin care technology at the moment. 

If you've looked into retinol usage tips, you've likely heard that you need to ease into it: starting sparingly, and working your way up to nightly use. And that's true! But what lots of folks don't know (myself included up until Darden told me during this episode) is that you need to do that every single time you switch retinol formulations.

"The biggest problem I see is when someone is like, 'Oh, I've used this retinol and my skin's freaking out.' So I usually say, 'Well, how did you start it?' And they're like, 'I started using it every other night because I was already using another retinol.' Nope—doesn't work that way," Darden explained. "It doesn't matter if you've used retinol in the past. They're all different: There are different ingredients formulated with it and different kinds of retinol. You have to start again and be patient." 

I asked Darden about finding that delicate balance between treating a skin concern (for example, fading a dark spot or treating acne) while not damaging the skin barrier. I think it's an issue lots of skin care devotees deal with, myself included. I want my routine to be effective, but I don't want it to come at the expense of my skin barrier's integrity. 

For Darden, it just comes down to making sure you're not overwhelming the skin elsewhere in the routine. This means you need to be very critical about the ingredients you're using in each step. 

We don't spend a ton of time in the depths of lifestyle skin care, but Darden notes she's a big believer that diet influences skin health. "I think eating clean is really important. Eating too many carbs, sugar, all of that does pay a toll on your skin. So just make sure you're careful about what you're eating," she says. "Of course, we all have to splurge, but if for the most part you're eating clean, you'll definitely see a big difference."

She notes this is especially true for those with acne. "[When I was an esthetician at a dermatologist's office,] I would see a lot of patients who were struggling with acne for so long, and changing their diet made a huge difference. What made the biggest difference was removing dairy," she says.
