4 Skin Geniuses Reveal Their Holy Grail Products

Home base: New York City Claim to fame: Patients in search of subtlety flock to need-to-know needle pro Zeichner, the director of cosmetic research in dermatology at Mount Sinai Medical Center, who prefers to "add volume and lift, rather than fill individual lines" for natural-looking results. "It's okay to have a wrinkle," he says. "You want to look good for your age, not plastic." Secret weapon: Zeichner injects hyaluronic-acid-based filler Voluma, which can last up to two years, "very deep—underneath the muscle, the fat, and the soft tissue"—to give definition to cheekbones. Quick fix: For patients unable to take the downtime for a skin-resurfacing procedure such as Fraxel, Zeichner recommends Neotensil, a topical that flattens out puffy undereye bags by forming an invisible film over skin for up to 16 hours: "It's a temporary solution until we want to treat the area another way." Cerave AM Facial Moisturizing Lotion (1) "provides barrier repair along with sun protection." Neutrogena Rapid Wrinkle Repair (2) is "a great entry-level retinol." Zeichner considers "antioxidant trifecta" Skinceuticals Phloretin CF (3) a daily essential. Olay Regenerist Micro-Sculpting Serum (4) "is rich in peptides that stimulate collagen production."

Home base: New York City Claim to fame: Jaliman streamlines silhouettes and tightens skin on faces and bodies with an arsenal of state-of-the-art lasers, fat freezers, and radio-frequency devices. With 2012's Skin Rules: Trade Secrets from a Top New York Dermatologist, she literally wrote the book on looking good. Secret weapon: Liposonix, which uses high-intensity ultrasound to shrink fat cells in a single session, is Jaliman's go-to gadget for body contouring: "It works incredibly well on saddlebags and love handles." Quick fix: For patients "who want to look great immediately," Jaliman loves non-ablative Laser Genesis, which stimulates circulation and collagen synthesis by gently heating the skin. "It gives an incredible glow with no downtime." A spritz of Avène Thermal Spring Water (1) after cleansing "helps balance skin's pH and soothe redness." Vaseline Intensive Care Advanced Repair lotion (2) "has a lot of the same ingredients as prescription moisturizers." Skinceuticals Epidermal Repair (3) "relieves inflammation, so it's therapeutic for compromised skin." Jaliman keeps Aquaphor Healing Ointment (4) on hand for use on ultrasensitive patients after laser treatments. "I've never seen an allergic reaction to it," she says.

Home base: Redondo Beach, CA Claim to fame: For Chiu, an even-toned, luminous complexion "will make anyone, regardless of age or race, look younger, more rested, healthy, and vibrant." A good at-home anti-aging regimen is key: "Invest in products that build collagen, because that alone will improve glow and brightness." Secret weapon: In-office peels are complexion-rejuvenating all-stars. "Laser technology is fabulous, but it's very problem-specific," Chiu says, "whereas a chemical peel can improve the overall canvas of the skin—the texture, tone, pore size, and discoloration—all at once, with minimal downtime, and across all skin types." Quick fix: Mix Greek yogurt with the liquid from a steeped green-tea bag, then apply it as a 10-minute mask for a DIY radiance boost. "The tea tightens pores and gives you instant brightness," Chiu says, "while the yogurt moisturizes and soothes." Patting a few drops of "moisturizing and plumping" Tata Harper Beautifying Face Oil (1) onto skin will "refresh bedraggled makeup" for a midday reboot. SkinMedica TNS Essential Serum (2), which contains "peptides, seven antioxidants, and growth factors," is Chiu's favorite multitasker. Exuviance Age Reverse BioActiv Wash (3) "breaks down the oil in pores so they look smaller." The hyaluronic acid in Murad Intensive-C Radiance Peel (4) "attracts moisture to the skin and gives you a dewy, refreshed look."

Home base: Nashville Claim to fame: Hanlon is sought after for her expertise in diagnosing and treating skin cancer: She's trained in Mohs, a specialized micrographic surgery that allows for the removal of carcinomas with minimal damage to the surrounding skin. Secret weapon: Hanlon uses photodynamic therapy to zap away precancerous lesions and to treat overall sun damage. There's "redness and some peeling" for about a week after the procedure, but "it also brightens the overall complexion." Quick fix: Manual exfoliation with a Clarisonic brush or gentle cleansing scrub "will remove dead, sun-damaged skin and get rid of the dullness that can happen with age," Hanlon says. Skin cancer on the lips can be very aggressive, so protection is important, Hanlon says. Sun Bum Sunscreen Lip Balm SPF 30 (1) "can easily be worn under sheer lip gloss or lipstick." EltaMD UV Daily Broad-Spectrum SPF 46 (2) "contains hyaluronic acid and vitamin E," so it's hydrating and quickly absorbed. ROC Retinol Correxion night cream (3) "can increase collagen and lighten freckles" without irritation. Hanlon uses Cetaphil Gentle Skin Cleansing Cloths (4) "to remove makeup and SPF before following up with a cleanser."
