Does Sunscreen Prevent Tanning?

While some people associate a tan with a “healthy glow,” the reality is a little less glamorous: Any change in your skin tone caused by the sun is actually a sign of damage. So does sunscreen prevent tanning?

In this post, we’re breaking down the science behind tanning, the role sunscreen plays in protecting your skin and how you can achieve sunkissed skin, without the sun damage.

First Things First: There’s No Such Thing as a “Healthy Tan”

Let’s clear up a common myth: Tanning isn’t a sign of health — it’s actually your skin’s way of signaling stress. When UV rays penetrate your skin, they trigger your body to produce more melanin (the pigment that gives skin its color) to shield itself from further damage.

Tanning is primarily caused by UVA rays, which are present year-round, can penetrate windows and clouds and are responsible for premature aging, wrinkles and dark spots. UVB rays, on the other hand, cause sunburns and can play a role in the development of skin cancer. This means that just because you don’t burn doesn’t mean you’re not experiencing damage.

While a bronzed complexion might seem like a vacation souvenir, it’s really a sign that your skin is trying to protect itself. That’s why dermatologists and skincare experts agree: The healthiest glow is the one that comes from good skincare, not sun exposure.

Does Sunscreen Prevent Tanning?

No sunscreen can block 100% of UV rays to completely prevent tanning. However, when used correctly and consistently, SPF can significantly reduce the amount of radiation reaching your skin.

This is why broad-spectrum sunscreen is key. It protects against both UVA and UVB rays. That said, you need to make sure you apply enough and reapply at least every couple of hours, otherwise you might be getting more UV exposure than you realize.

For optimal protection:

Use at least SPF 30
Apply generously, making sure to follow the instructions on the label.
Reapply every two hours, or immediately after swimming, sweating or toweling off. Always follow the directions on your bottle.

By making sunscreen part of your daily routine, you can help keep your skin safe while maintaining a healthy, even complexion.
