A top-notch dermatologist is a must for any celebrity who finds themselves in front of a camera or on the red carpet. Flawless, ageless skin takes effort, and the proper mix of prevention and correction with skincare and in-office treatments is essential for a picture-perfect complexion. These are the doctors the stars have on speed-dial—along with the products they use between appointments.

The dermatologist: Dr. Macrene Alexiades
The skincare line: 37 Actives
The celebrity devotees: Rosie Huntington-Whiteley, Hannah Bronfman, Erin Wasson

With a line of products called 37 Actives (as in active ingredients—but there are now more than 50), you know New York City dermatologist Dr. Macrene Alexiades means anti-agingbusiness. With an unwavering dedication to science, independent clinical testing (and results that prove the products work), each 37 Actives product is formulated with a specific blend of both high-tech and natural ingredients that protect, strengthen and rejuvenate the skin (without the use of parabens, phthalates and such). And be sure to keep an eye out for the brand-new High Performance Anti-Aging and Filler Serum!

The dermatologist: Dr. Frederic Brandt
The skincare line: Dr. Brandt Skincare
The celebrity devotees: Madonna, Kelly Ripa, Donna Karan, Calvin Klein, Gwyneth Paltrow

Dr. Brandt sadly passed away in 2015, but he left an indelible mark on the world of beauty as both an artist and a trailblazer. Often referred to as the “Baron of Botox,” he was known for dramatic yet natural-looking rejuvenation without picking up a scalpel, and was a pioneer in the injectable and dermatologist-created skincare arenas. Dr. Brandt’s legacy lives on in his cutting-edge brand, which continues to innovate with advanced technologies designed to mimic the results of in-office treatments and procedures. The brand’s latest eye cream, No More Baggage, minimizes the look of puffiness in just five minutes and works to improve the overall appearance of the under-eye area over time.

The dermatologist: Dr. Harold Lancer
The skincare line: Lancer Skincare
The celebrity devotees: Kim Kardashian, Victoria Beckham, Jenna Dewan Tatum, Hilary Duff, Ryan Seacrest

Hailing from Beverly Hills, you’d think dermatologist Dr. Harold Lancer would have a “more is more” philosophy when it comes to skincare, but his renowned “Lancer Method” centers around three simple steps: Exfoliating, cleansing and nourishing (and there are systems for normal, sensitive and blemish-prone skin). Sure, you can add “Advanced Treatments” to brighten, retexturize, firm and more, but the “Lancer Glow” you see in his patients’ “off duty” paparazzi shots speaks for itself.

The dermatologist: Dr. David Colbert
The skincare line: Colbert MD
The celebrity devotees: Sienna Miller, Michelle Williams, Rachel Weisz, Naomi Watts

Starlets and models flock to this New York City dermatologist before big events (such as the Victoria’s Secret fashion show) for his signature Colbert MD Runway Facial. Performed as a series over a few months’ time, this “facial” features a combination of microdermabrasion, laser treatments, chemical peels, LED light massages and radiofrequency (depending on the individual patient’s needs) to deliver an ageless complexion and otherworldly glow. Between sessions, Dr. Colbert’s skincare line boosts improvement at home thanks to three basic yet highly effective steps that promote cellular renewal—and flawless skin.

The dermatologist: Dr. Barbara Sturm
The skincare line: Dr. Barbara Sturm Skincare
The celebrity devotees: Cher, Hailey Baldwin, Jada Pinkett-Smith, Kate Moss

Though not a dermatologist (but a physician nonetheless), molecular-orthopedist-turned-aesthetic-specialist Dr. Barbara Sturm made an international name for herself by creating MC1, a facial cream that’s customized with an individual patient’s blood—but it’s more complicated than that. After blood is taken, it is funneled through a special vial that prompts the blood to react as if an injury has occurred, in turn activating the regenerative proteins that patients swear are worth every penny of the $1,400 price tag. Think of it as a vampire facial in a jar, but you’ll have to go to one of her offices in Düsseldorf or Munich, Germany to get it. But on the bright side, she has an expansive product line that you can purchase online from the comfort of your own home.
