There are so many gimmicky skincare trends out there, but very few of them are truly based on science. One of the few exceptions is covered in detail here: https://ways2well.com/blog/stem-cell-for-cosmetics-revolutionary-treatments-for-skin-care. The article describes how stem cells from plants, fat, and skin are used in advanced treatments to rejuvenate the skin at the cellular level. This approach is regenerative, not just cosmetic - it stimulates the body's own repair mechanisms. These stem cell-based products and treatments support skin health in the long term, rather than offering a temporary fix on a superficial level. Definitely worth a read if you're serious about skin science.
