The science behind skin care has been progressing at a faster and faster rate of speed. Twenty years ago, had you mentioned stem cell use in association with mainstream skin care, people would have stared at you as though you had three heads and steered their children in a path far around you.
Reality today paints a much cooler picture. One where stem cells are used to treat a variety of blood and bone marrow diseases, blood cancers, and immune disorders. And we are finding stem cells, both human and plant, on the ingredients lists of some very powerful and effective skin care products. Stem cell use in skin care products is coming of age.
What Are Stem Cells?
Stem cells are a type of cell that are found in all living things and have the glorious ability to differentiate themselves into many different types of cells. They are capable of becoming any other type of cell in that type of organism and reproducing in a controlled manner. As a result, they are the building blocks of your tissues and have the unique ability to replace damaged and diseased cells. They can proliferate for long periods, dividing themselves over and over again into millions of new cells. That means they can play a pivotal role in how skin repairs itself.
“Stem cells are extremely beneficial in the natural process of healing and regeneration,” says Jessica Weiser, M.D., a board-certified dermatologist in New York City.
Many beauty products contain stem cells from fruits like Swiss apples, edelweiss, roses, date palms, grape, raspberry, lilac, and gotu kola that have the ability to stay fresh for long periods of times.
Human stem cells come from one of two sources: embryonic stem cells and adult (somatic) stem cells. For the case of skin care, stem cells of the adult origin are used. They remain in the body quietly in a non-dividing state for years until activated by disease or injury.
What Can Stem Cells Do For the Skin?
Because they play an essential role in tissue removal, stem cells residing just below the surface of the skin can help with restorative functions, such as cellular regeneration, and could play a vital role in helping to enhance our ability to repair aging skin.
You start off with an abundance of stem cells in your skin, but you lose them as you age. By the time you hit 50, you’ve lost about 98% of them.
The working theory is that by applying products containing stem cell extracts, you could encourage the growth of your own skin’s stem cells and possibly wake them up to trigger their anti-aging effects. Some research suggests that they can promote the production of collagen, which is the body’s firming protein.
Are There Real Live Cells In Skin Care Products
Live cells need very specific conditions to remain alive and viable. It’s difficult enough to maintain those conditions in a laboratory setting. Skin care products and their environments don’t offer those types of conditions. When stem cells are included in skin care products, makers aren’t looking to provide you with live, functional cells. Extracts from the stem cells, not the actual cells themselves, are usually added to skin care products. “It’s not possible to maintain live stem cells in cosmetic emulsions,” says Zoe Diana Draelos, a consulting professor of dermatology at the Duke University School of Medicine in Durham, North Carolina.
Most stem cell products you see on the shelf don’t actually contain stem cells, but rather the proteins and amino acids that those cells secrete. Typically, if you see a product labeled as a stem cell product, you’ll see the stem cell’s key substances in the ingredients list. These include ferulic acid, ellagic acid, and quercetin. This is what your body is able to recognize and put to use to help rejuvenate and repair cells. Human stem cell byproducts (from skin or adipose tissue) seem to be the best solution for use in skin care products because of their ability to produce the same types of cellular components that your body uses naturally to maintain a youthful appearance.
Cultivating stem cells is a tedious process involving a very controlled environment without any contaminants in order to yield the most potent, stable, and pure extract. Because of this technology, the cost of stem cell products are usually greater than products without.
