Willowbrook, IL dermatologist Jessie Cheung, MD adds that the timing is just as important as the order, too. “The best time to start these treatments is while you’re losing weight,” she explains.

“When we talk about loss of skin elasticity after weight loss, it’s not just about the skin being ‘stretched out,’” Dr. Cheung explains.

“When patients are losing weight, especially quickly or while on GLP-1 medications, I often see nutrient deficiencies that first show up in the skin, hair and nails,” says Dr. Cheung.

More than just a trend, ectoin is leading a new wave of barrier-supportive skincare. “It’s not just hype,” adds dermatologist Jessie Cheung. “Ectoin has decades of medical research behind it, and now we’re finally seeing it used to strengthen and future-proof the skin.”

Cheung also says that “ingredients that help firm and strengthen your skin, including retinol and antioxidants, will help to fight puffy eyes,” too.

Tubing mascara is also easier to remove than traditional mascara, so you don’t have to use harsh cleansers or scrub aggressively with makeup remover to take it off, which helps protect the integrity of your existing lashes, explains Jessie Cheung, MD, a board-certified dermatologist and founder of Cheung Aesthetics & Wellness in Chicago.

Board-certified dermatologist, Dr. Jessie Cheung emphasizes that "a good full body deodorant should differ from a perfume, not merely masking odor, but by supporting non-stinky bacteria."

“I was lucky enough to receive Rejuran injections in Korea less than a month ago, and my skin is still glowing, smooth, and tight,” she says.

“Using a tinted moisturizer with SPF is even better, as you’re saving time using three products in one,” says board-certified dermatologist Dr. Jessie Cheung. Tinted moisturizers also help to eliminate the struggle of finding sunscreens that don't leave a white cast.

“A blackhead forms when oxygen reacts with dead skin cells and sebum, plugging up the pore,” says Jessie Cheung, MD, a board-certified dermatologist.

Vitamin C is inherently unstable and quickly broken down when exposed to light and/or oxygen. For that reason, board-certified dermatologist Jessie Cheung, MD suggests looking for products that come housed in opaque bottles or have an air-tight pump dispenser.

All of the dermatologists use at least one serum in their regimens under day and night creams and Dr. Cheung uses a startling four (you can layer them).
