It turns out the old adage is true: and an apple a day may help keep the doctor (or plastic surgeon) away. That Eve was onto something...
From a consumption standpoint, apples offer a lot of bang for the buck. High in fiber, they help regulate blood sugar and ward off sugar cravings. Spikes in insulin ultimately wreak havoc on the body’s ability create new collagen, causing skin to become lax and wrinkled. Granny Smith & Red Delicious apples in particular contain high levels of collagen and elastin, both beneficial to healthy, youthful skin. Apples are also rich in a variety of polyphenols, the varying with the type of apple, and is also a source Vitamin C, though not a major one.
Topically, apple extracts are used in a variety of formulas designed to lighten dark spots caused by sun exposure, speed up cell turnover, brighten dull complexions, decrease wrinkles and to improve overall texture and tone. For example, Juice Beauty uses organic apple juice as their star ingredient, along with a host of other potent anti-aging ingredients such as in their Age Defy Green Apple Collection, designed to “brighten, lighten and tighten”. Naturally occurring malic acid (an alpha hydroxy acid) helps dissolve dead skin cells and is especially beneficial to those with oilier skin to help clear up blackheads and regulate oil production. If you're skin is sensitive, this range isn't for you.
If you'd prefer a DIY approach, try apple cider vinegar. Use a solution of 1 part water:1 part apple cider vinegar for a skin treatment that’s naturally rich in malic acid. Used as a toner, it will refine skin, helping to dissolve dead surface cells and balance pH. For those with more sensitive skin, it may be wise to rinse after letting it sit for 10-15 minutes. You may never look at an apple the same again.
