We all want to fight the signs of aging and so we go to the malls, our Estheticians and Dermatologists, hoping they will have the answer, maybe even the cure for our wrinkles. From fighting free radicals to stimulating skin’s natural collagen production, anti-aging products make enticing promises.
Do they work? That’s what we want to know, right? Below I have listed 4 commonly listed ingredients and some evidence on whether they actually play an effect on your skin.
As we age our skin gets thinner, loses fat and starts to sag and develop fine lines and wrinkles. We produce less collagen and elastin to keep our skin firm and plump.
Peptides are small proteins that help stimulate new cells to grow and to help skin cells to heal.
Scientists are still not sure how beneficial these actually are because of the size of the molecule. They are rather large and that makes it more difficult to deeply penetrate the skin. They can, however, do some good in a moisturizer. This way they can hydrate the skin and make lines less noticeable. Whether they reduce wrinkles, the jury is still out.
Alpha-Hydroxy Acids (AHA’s)
Examples are glycolic, lactic and citric acids which are natural ingredients that come from fruits and milk sugars. They are great for exfoliation because they get rid of dead skin cells, allowing new cells to grow.
Each acid does something different for the skin. Lactic Acid (comes from sour milk) removes the dead skin cells so this will have a brightening effect. Glycolic Acid (comes from sugar cane) helps reduce fine lines and wrinkles which can make skin look smoother and tighter.
A natural form of Vitamin A, this boosts the thickness and elasticity of the skin therefore reducing the signs of wrinkles.
There is an abundant amount of evidence to support that retinol works! Finding it in the right products is the tricky part because you need to have enough to get results. Most over-the-counter products cannot put enough retinol in them to give you the benefits you need. See your Esthetician (me!) or a Dermatologist to get the good stuff! :)
Help fight cell damage from free radicals, which are molecules that could injure cells and increase inflammation.
There are many antioxidants that are effective, however, the formulation is the most critical. Vitamins C and E are the most commonly used and time-tested.
