Staple ingredients in skincare have stayed relatively consistent in recent years, but the future holds promise for more, according to Dermatologist Manjula Jegasothy, M.D.
“We all know about retin A. We all know about glycolic acid and salicylic acid and, of course, how great vitamin C is,” says Dr. Jegasothy, Miami Skin Institute, Miami, Fla.
So, what’s next in the science of skincare? That’s the question Dr. Jegasothy addressed in the cosmeceutical expert panel at Cosmetic Surgery Forum 2019.
“I think that the future is really studying more about prebiotics, probiotics and even the proteins that the probiotics make, which are called postbiotics… all of those things play a very significant role on the surface of our skin,” she says.
According to Miriam Webster:
Prebiotic is defined as, "a substance and especially a carbohydrate (such as insulin) that is nearly or wholly indigestible and that when consumed (as in food) promotes the growth of beneficial bacteria in the digestive tract."
A probiotic is "a microorganism (such as lactobacillus) that when consumed (as in a food or a dietary supplement) maintains or restores beneficial bacteria to the digestive tract. also: a product or preparation that contains such microorganisms."
“The newest member of the biotics family, postbiotics, refers to bioactive compounds produced by food-grade microorganisms during a fermentation process. Postbiotics include microbial cells, cell constituents and metabolites,” according to Wegh et al. in a recent article that examines the potential applications of postbiotics.1
As future research strives to create a cleaner environment free from bacteria, the National Center For Health Research warns that doing so also contributes to rising incidence in cancer, obesity, cancer and cardiovascular disease. “Experts are trying to figure out how ‘probiotics’… can improve our health,” according to the NCHR.
