There is a particular kind of skincare ingredient that arrives without much noise and then quietly becomes indispensable. Growth factors have followed that path. They have been used in clinical and post-procedure settings for years, largely away from the beauty conversation, and are now appearing in routines built by people who read ingredient lists carefully and are unmoved by packaging.
The appeal is easy to understand once you know what they do. Most skincare supplies the skin with something it needs. Growth factors take a different approach, working with the signaling system that determines how skin repairs itself. At NakedBeauty MD, they are foundational to how we formulate, and this is our account of why.
What Growth Factors Are and How They Work
Growth factors are naturally occurring proteins that act as messengers between cells. They bind to receptors on a cell's surface and trigger specific responses: proliferate, migrate, produce collagen, initiate repair. The body relies on them constantly, most visibly during wound healing, when a coordinated cascade of growth factor signaling directs the rebuilding of damaged tissue.
Skin produces fewer of these proteins with age, and the cells receiving them become less responsive. Fibroblasts slow their collagen production. The extracellular matrix, the structural scaffolding that keeps skin firm and resilient, is maintained less efficiently. The visible consequences are the ones everyone recognizes: thinner-looking skin, less bounce, lines that settle rather than fade, and a slower return to normal after any kind of insult.
The premise behind topical growth factors is that supplying these signaling proteins may help support the repair pathways that have become less active. Gidumal and colleagues, writing in Facial Plastic Surgery Clinics of North America in 2026, review the biology connecting stem cells, growth factors, and peptides in skin improvement, and describe how these pathways overlap and reinforce one another.
The Evidence Base
Growth factors have a longer clinical history in topical use than most newer regenerative ingredients. Atkin and colleagues, publishing in the Journal of Cosmetic and Laser Therapy in 2010, studied physiologically balanced growth factors combined with antioxidants for facial photodamage and reported measurable improvement. Dayan and colleagues examined topical skin therapies in subjects undergoing full facial rejuvenation in the Journal of Cosmetic Dermatology in 2019.
More recently, Abud and colleagues published a randomized, double-blinded pilot study in the Journal of Cosmetic Dermatology in 2026 comparing synthetic against human-derived topical epidermal growth factor, which speaks directly to a question worth asking about any growth factor product: where the proteins come from and how they were made. Research on the adjacent peptide category has also matured, with Nukaly and colleagues publishing a systematic review and meta-analysis of randomized controlled trials on oral and topical peptides for skin aging in Frontiers in Medicine in 2026.
The honest summary is that growth factors sit on firmer evidential ground than several ingredients marketed with greater confidence, while remaining an area where formulation quality determines whether the biology translates into anything you can see. Topical growth factor products are cosmetics and have not been evaluated by the FDA for the treatment of any condition.
What Separates One Growth Factor Product From Another
Proteins are fragile. They are considerably larger than most skincare molecules, sensitive to heat, light, and pH, and prone to losing function during manufacturing or on a shelf. A product can contain growth factors and still deliver very little if the proteins have degraded before the bottle is opened.
Three variables determine whether a formula performs. The first is source and production method, which govern the type of growth factor and its stability. The second is concentration, which is rarely disclosed and which separates a formulation decision from a label decision. The third is the surrounding formula, because a growth factor asking cells to build collagen produces more when the environment supports that request and less when it is fighting oxidative stress or a compromised barrier.
This is the reason single-ingredient thinking tends to disappoint. The pathways involved in skin repair are interconnected, and supporting one input while ignoring the others produces a smaller return than the ingredient itself would suggest.
Who Growth Factors Tend to Suit
The people who benefit most are generally those whose skin has begun to lose firmness and resilience rather than those managing an active concern like acne or persistent pigmentation, which respond better to other categories. Anyone in their thirties onward who has established the fundamentals of sun protection, barrier support, and a proven active will find growth factors a logical addition rather than a replacement.
They are also worth considering after in-office treatments, which is where the category originated. Procedures that create controlled injury rely on the skin's repair response to produce their result, and supporting that response during recovery is the reasoning behind their long-standing use in post-procedure protocols. Timing should follow the guidance of whoever performed the treatment.
The NakedBeauty MD Standard
NakedBeauty MD was founded by Dr. Catherine Chang, M.D., F.A.C.S., a Harvard-trained, board-certified plastic and reconstructive surgeon with subspecialty expertise in craniofacial aesthetic surgery. She trained at Columbia University, the University of Pennsylvania, and Harvard Medical School's Massachusetts General Hospital, leads Privé Beverly Hills, and has been named among America's top surgeons by Newsweek.
The line exists because of a specific observation. Her patients valued the luminosity of their skin after procedures as much as the refinement of their features, and they wanted to keep it. Building formulas to that brief meant they had to hold up next to clinical work rather than simply sit beside it, which is a demanding standard and the reason our collection contains four products rather than forty.
Each has a defined role. The ExoGlow Multi-Action Face Serum is the treatment step, combining growth factors with exosomes, peptides, and antioxidants across 26 actives to firm, brighten, and renew while supporting the skin's own hyaluronic acid production and providing blue light protection. The BioPeptide Growth Factor Eye Therapy applies the same approach to the eye area, where skin is thinnest and change appears first, and is tested for sensitive skin. The BioPeptide Firming Hydrogel Face Mask delivers actives under occlusion for a concentrated treatment. The Damask Rose Revitalizing Gold-Infused Hydrogel Eye Masks are the recovery step Dr. Chang originally developed to reduce inflammation and support healing after in-office work.
Our formulas draw on more than 30 actives in total, including Copper Tripeptide-1 for collagen and elastin, Palmitoyl Pentapeptide-4 for firmness, Theobroma Cacao for blue light defense, Ceramide NP for barrier reinforcement, and Centella Asiatica for calming and repair. The complete list is published on The Science page, because we think anyone considering a purchase at this level should be able to read exactly what they are buying.
Building Growth Factors Into a Routine
Growth factor products belong on clean skin before heavier creams, giving the actives unobstructed access. They layer well with most routines and combine particularly effectively with antioxidants and daily sun protection, since preventing new damage makes any repair-supporting ingredient more productive.
They also pair sensibly with retinoids, though the two are usually best separated between morning and evening if your skin is reactive. If you have been layering many single-ingredient serums, consolidating into one well-built multi-active formula often produces a clearer result, simply because there are fewer variables and fewer opportunities for ingredients to work against each other.
What to Expect
Collagen remodeling is slow biology, and it does not accelerate because a product is expensive. Hydration and surface radiance typically improve within two to four weeks. Texture and tone shift between six and twelve weeks. Firmness and elasticity, where they develop, do so over three to six months of consistent use.
Consistency is the variable most within your control and the one most often abandoned. A well-formulated serum used sporadically for a year will do less than a moderate one used every day for three months. We would rather set that expectation clearly than have anyone conclude after a fortnight that the category does not work.
Growth factor formulations suit most skin types, including sensitive skin. Anyone who is pregnant or nursing, has an active inflammatory skin condition, or has a personal history of skin cancer should speak with a physician before introducing any new regenerative active, and new products are always best introduced one at a time.

Growth factors are gaining attention because the underlying biology is sound, the clinical history is longer than most people assume, and the results, when the formulation is done properly, are the kind that accumulate rather than announce themselves.
