Yes, tanning can make you look older. The sun’s UV rays damage the collagen in your skin, causing it to sag and wrinkle if you tan excessively. This can make you look older than your years. So while a tan may give you a temporary youthful glow, if you overdo it, it’s more likely to age you. It’s important to protect your skin from the sun with sunscreen or clothing to help prevent this from happening.
