As we age, our skin gets thinner and drier, two descriptions no one ever wants to apply to his or her face, for sure. Some anti-aging products on the market, usually those that contain retinoids or alpha-hydroxy acid, can make dry, irritated skin worse. As part of a skin care regimen for mature skin, petroleum jelly can help soothe dryness and flakiness, as well as help reduce the appearance of fine lines and wrinkles (it's not going to take away wrinkles, but it will make them less noticeable). Use it as a daily moisturizer, daily makeup remover and even as a way to prevent wind burn.
Be careful to only use heavy oil-based moisturizers on excessively dry skin -- if your face is normal or normal to oily, use the petroleum jelly everywhere but here.
