🧡Collagen is what determines how smooth your skin is.🧡 Exercise increases the flow of nutrients and water to the skin’s surface, making collagen denser so your skin looks younger.🧡 Your skin renews itself every 28 days. As you age, it takes your skin longer to renew itself.🧡 Caffeine, nicotine, and alcohol constrict blood vessels and prevent nutrients from nourishing the skin, thereby accelerating the aging process.🧡 The skin around your mouth is 200 times more sensitive than your fingerprints.🧡 It’s true that lips are the most sensitive part of the body.🧡 Oily skin is more prone to breakouts, but less prone to wrinkles.🧡 Skin color is caused by melanin, which protects against UV rays.
