They use toner instead of face wash in the morning.
If you've noticed that you get intensely greasy and suffer from breakouts despite all efforts to stop producing sebum, you only have yourself to blame. Washing your face too frequently can strip your skin of its natural oils, throwing your complexion's balance out of whack. (And yes, that can lead to overproduction of face grease.)
"I recommend cleansing your skin at night only," Pekar suggested. Swap your morning face wash for a toner, which will gently cleanse and refresh your complexion. "Most importantly, it will balance your skin's pH so it is not too oily and not dry."
They reduce their sugar intake and keep their weight consistent.
Besides being excellent for your health, cutting back on sugar benefits your skin. "It causes breakouts and actually speeds up aging, prematurely showing wrinkles and fine lines," Pekar explained. This is due to a natural process called glycation. The sugar in your bloodstream forms molecules that destroy collagen and elastin (which keeps skin firm). Avoiding sweet treats can actually help you avoid aging.
Yo-yo dieting can also wreak havoc on your complexion. "When your weight fluctuates, you are constantly stretching out your skin, which will affect its appearance," Pekar said. This is true for your face as well as your body — though stretch marks may be an especially obvious side effect.
