Diet, sleep, and exercise affect the way we look. Cosmetic companies will tell you that taking certain vitamins is needed to look great. However, there are some that do not work well. Biotin, Vitamin E, Vitamin A, and Zinc are trusted vitamins that don’t actually perform this task well. However, Collagen, Probiotics, and Omega-3 do.

Key Takeaways:

• The go-to ingredient that’s found in almost every beauty vitamin formulation, biotin has long been associated with long, strong tresses.
• The body needs biotin, also known as vitamin B7, to metabolize fats and proteins. Because it’s partially responsible for new cell production, biotin gained a reputation for hair and skin health.
• But unless you’re severely deficient, there’s very little evidence that proves it encourages hair growth or younger-looking skin.

“There’s a reason beauty editors everywhere love retinol products—they really work. Retinol is one of the most powerful anti-aging and smoothing ingredients around because it encourages cell turnover and the growth of new skin cells.”
