As GLP-1 medications continue to dominate weight-loss conversations\u2014among physicians in clinical settings and regular people over happy hour alike\u2014an influx of new trends, buzzwords and even products has followed. We\u2019re seeing restaurant menus built around higher-protein needs and smaller appetites, supplements meant to support muscle mass and, more recently, skin-care products claiming to help address post\u2013GLP-1 skin laxity.<\/p>\n
That\u2019s where things start to get murky. When it comes to skin laxity, experts say there\u2019s a clear difference between what a cream can do and what usually requires an in-office treatment. With that in mind, I spoke with two experts\u2014a board-certified dermatologist and a facial plastic surgeon\u2014to find out whether GLP-1 firming skin care is actually a smart addition or just smart marketing. Here\u2019s what they had to say.<\/p>\n
Featured Experts<\/h2>\n\n- Paul S. Nassif, MD\u00a0is a board-certified facial plastic surgeon in Beverly Hills, CA<\/li>\n
- Kristina Collins, MD is a board-certified dermatologist in Austin, TX and the founder of Foy by Dr. Collins<\/li>\n<\/ul>\n
Why GLP-1 Weight Loss Can Cause Loose Skin<\/h2>\n
Rapid weight loss can bring noticeable changes to the skin. \u201cWhen someone loses weight quickly on a GLP-1, the skin may look looser because you\u2019ve lost underlying volume and support,\u201d explains Beverly Hills facial plastic surgeon Paul Nassif, MD. \u201cA cream cannot replace that structural support the way collagen, fat and ligaments do.\u201d<\/p>\n
Austin, TX dermatologist Kristina Collins, MD says how the skin responds after weight loss can vary widely. \u201cSkin can tighten on its own to a certain degree, but it depends on factors like age, genetics, how quickly the weight was lost and how long the skin was stretched. Younger skin with healthy collagen and elastin tends to rebound better, especially when weight loss is gradual and muscle mass is maintained.\u201d<\/p>\n
\u201cHowever, when weight loss is significant or rapid, the collagen and elastin fibers that give skin its structure can become overstretched and damaged,\u201d Dr. Collins continues. \u201cIn those cases, the skin may not fully retract on its own. Mild laxity can improve over time, but moderate to severe loose skin often requires treatment.\u201d<\/p>\n
What Skin Care Can (and Can\u2019t) Do for GLP-1 Skin<\/h2>\n
Dr. Collins says the recent wave of products marketed for \u201cGLP-1 skin\u201d doesn\u2019t reflect how the medications actually work in the body. \u201cMost \u2018GLP-1 skin care\u2019 is more of a marketing concept than a new scientific category,\u201d she says. \u201cGLP-1 medications work internally by affecting hormones and metabolism, so a topical product cannot replicate those systemic effects.\u201d<\/p>\n
Instead, products labeled for \u201cGLP-1 skin\u201d are typically marketed as addressing visible changes associated with rapid weight loss, such as dryness, laxity and the appearance of facial volume loss. Ultimately, she cautions, their effectiveness comes down to the ingredient list.<\/p>\n
Ingredients That Can Help Skin Look Firmer<\/h2>\n
Some ingredients do have evidence behind their ability to support skin quality. \u201cFor firmer-looking skin, I look for ingredients that support collagen production, improve elasticity and strengthen the skin barrier,\u201d Dr. Nassif says. \u201cRetinoids are proven to improve the appearance of fine lines and support collagen production over time.\u201d<\/p>\n
He says peptides can also help improve skin function and hydration, while niacinamide supports moisture levels and strengthens the skin\u2019s structural proteins. \u201cOther collagen-producing ingredients include vitamin C and epidermal growth factor, which signals cells to increase collagen and elastin production,\u201d he adds. Hydration matters, too. \u201cHyaluronic acid is one that plumps the skin and smooths wrinkles because it pulls water into the dermis.\u201d<\/p>\n
What Skin Care Can\u2019t Do for Skin Laxity<\/h2>\n
Even the most effective topical ingredients have limits when it comes to structural skin changes. \u201cBecause significant laxity involves deeper structural changes, topical products alone usually aren\u2019t enough,\u201d says Dr. Nassif. \u201cTopicals can realistically help with crepey texture and dehydration, as well as fine lines and surface roughness. Many people on GLP-1s report dietary changes that can reflect in the skin and can negatively impact the skin barrier function.\u201d<\/p>\n
Skin care has its place, but in-office treatments including fillers, injectables and fat grafting can also play a role, adds Dr. Nassif. \u201cIf there is a significant amount of extra skin, that is more structural and you would need more than just skin care.\u201d <\/p>\n
Oftentimes, the most effective strategy involves both skin care and procedures. \u201cWhen you combine skin care and in-office procedures, you get the best outcome because even if you do a treatment, you still want that skin barrier strong, hydrated and supported so results look smoother and more refined,\u201d Dr. Nassif says.<\/p>\n
The Best Firming Skin-Care Products<\/h2>\n
