Anti-wrinkle creams offer a ton of empty promises from fighting against free radicals, to stimulating the skin to naturally produce collagen, which will magically rejuvenate you. According to Dr. Neil Niren, Board Certified Dermatologist specialized in medical, surgical and esthetic dermatology, Americans spend billions of dollars each year on such creams and lotions.
Unfortunately, they is no actual, scientific prove that creams and lotions reduce wrinkles or slow down premature aging. Although some active ingredients used in these products are proven to be safe and effective, the trick is to find the right ingredients that agree with your skin, says Niren.
Alpha-Hydroxy acids such as lactic, glycolic and citric acid are all natural ingredients which can be found in fruit and milk sugars. They are quite useful, as they release dead skin cells, allowing new cells to grow, shared Niren. They allow deeper skin layers of the skin to quickly come to the surface.
Each acid has a slightly different effect. Lactic acid, which comes from sour milk, helps move dead skin cells. Glycolic acid, which comes from sugar cane, can help in reducing lines and wrinkles, making the skin look smooth and stretch. But there are also some side effects that include burning and sun sensitivity, so Neil Niren M.D. recommends using sunscreen along with anti-aging creams.
Peptides are small proteins that help stimulate new cells to grow and assist skin cells to heal. Scientists are still experimenting to determine whether they are indeed useful, as we still do not know what the biological benefits of peptides are. Although peptides are found in numerous products, experts are still not sure that the formula really works. What concerns Niren is that as peptides form larger molecules, depending on their formulation and the skin surface, they cannot penetrate deep enough to achieve the desired effect.
Nowadays, the market is crowded with products and ingredients that promise efficiency. It can be devastating for patients and doctors as well, because it is difficult to know which work and which do not.
