Julia Roberts’ Aesthetician Shares Her Best Glowing Skin Tips

Known for her transformative, glow-inducing treatments and a client list that includes international A-listers, Keren Bartov has become synonymous with high-performance skin care that fuses science, precision and artistry. Now, with the debut of her coveted product line at New York’s Bergdorf Goodman, Bartov is bringing her clinic’s results-driven philosophy to beauty lovers everywhere, bottling the radiance that made her one of the most sought-after experts in the world.

As for her secrets to glowing, healthy skin? Below, Bartov shares the expert-approved rules she lives by.

Personalization Is Key

Every treatment begins with an in-depth skin diagnosis, not a one-size-fits-all protocol (she’s very proud that she has no treatment menu and that all treatments start with a detailed medical questionnaire). “No two skins are alike,” Bartov says. “I study texture, hydration, elasticity, pigmentation and sensitivity before crafting a personalized plan.” Her goal: balance, radiance and long-term skin health—not just an instant effect.

Rely on Technology

With more than 50 medical-grade technologies available, each of Bartov’s sessions combines around five, depending on the skin’s condition. These may include IPL, radiofrequency, fractional therapy, cold plasma and microneedling. After just one treatment, clients notice visibly smoother skin, minimized pores, a more even tone and a luminous glow that continues to develop in the days that follow.

Go for the Glow

What’s often dubbed the “celebrity treatment” is actually Bartov’s Glow Treatment—a pre-event protocol designed to deliver instant radiance, lift and sculpting before red carpets or photoshoots. Regular clients, including celebrities, visit year-round for customized balancing sessions that maintain skin health and vitality. “Every treatment is crafted with the same precision and care,” she emphasizes.

Active Ingredients Get the A-Plus

Active ingredients are the cornerstone of Bartov’s skin-care philosophy. She relies on next-generation peptides, advanced acids, plant-based fatty acids and patented actives proven to perform. Her hero product? The Advanced Skin Serum ($180), a deeply hydrating formula that strengthens the skin barrier and restores luminosity from within.

Cleansing Should Be Calculated

“Clean, hydrated skin is the gateway to glow,” says Bartov, who has a very specific cleansing routine she recommends: a gentle yet thorough cleansing ritual of a facial cleanser followed by micellar water at night, and micellar water alone in the morning. “This ensures active ingredients penetrate effectively without disrupting the barrier.”

Post-Treatment Care Is to Be Taken Seriously

While most of Bartov’s treatments leave no redness, intensive procedures may cause temporary flushing that fades within hours. “My approach is always visible results with zero downtime,” she explains. Even pre-event treatments are selected specifically to avoid irritation, so clients can return to daily life (or the spotlight) immediately. For the first 24–48 hours, avoid direct sun, heat and strong actives. “Keep it simple,” Bartov advises. “Gentle cleansing, hydration and SPF.” During this period, the skin continues to renew naturally, and simplicity ensures optimal results.

Remember That the Skin Loves Rhythm

To maintain that post-facial luminosity, Bartov recommends her Peel & Glow Booster Serum ($195), Hydra Reboost Cream ($180) and Advanced Skin Serum. These staples keep hydration, radiance and firmness intact between visits—especially when paired with consistent SPF use. For best results, Bartov suggests getting a facial every four to six weeks. “Skin loves rhythm,” she says. “Over time, the glow becomes your natural state.”
