When it comes to beauty life goals, it seems that finding the perfect red lipstick or mastering beach waves pales in comparison to the importance of achieving flawless skin. I spoke with Dr. Frauke Neuser, P&G principal scientist, global skin and personal care, and asked her what the scientific equation was for complexion perfection.

"It's never just about sleeping eight hours, using a product, or having the right genes — life is more complex than that," Frauke explained. "Despite this caveat, there are definitely a couple of really great skin care ingredients. If you use them and you do everything else right, you will have fantastic skin." So, you know that you should be wearing sunscreen and never smoke, but what ingredients are going to give you model-worthy skin? Don't look to retinol.

While many dermatologists would say that it's the top antiaging ingredient, Frauke is not convinced. "I'm not a big fan. There are people that we call 'retinol nonresponders,' who get zero benefit." While getting no rewards out of using your skin care, it could be worse: she said that other people have really bad reactions to it, like serious breakouts, itching, and redness. Instead, Frauke suggested an ingredient you aren't using to get brighter, more beautiful skin.

The magic ingredient is niacinamide, also known as vitamin B3 and nicotinic acid. If you're not sure if it's right for you, trust us — it's a total powerhouse. It brightens skin tone, fades discoloration, and improves elasticity. It even fades those red marks left behind by a bad breakout. "There is a lot of research that says it's good for overall aging," explained Frauke, adding that their niacinamide researcher faithfully takes supplements of the ingredient because of its powerful benefits.
