Sunscreen is an essential part of any skincare routine, but decoding its jargon can often feel like a challenge. From SPF to PA++++, here’s your simplified guide to understanding what those terms really mean and how they protect your skin.
What Really is SPF?
SPF stands for Sun Protection Factor. It measures how well your sunscreen shields your skin from UVB rays, which cause sunburn. For instance, an SPF50 sunscreen allows you to stay in the sun 50 times longer without burning than if you had no protection at all. However, remember that SPF only addresses UVB rays, so a higher number doesn’t mean complete sun protection.
What is UVA?
UVA rays penetrate deep into your skin, leading to premature aging, wrinkles, and even long-term skin damage. Unlike UVB rays, they don’t cause sunburn but are equally harmful as they damage skin cells over time.
Then What is UVB?
UVB rays are the ones responsible for visible sunburn. They affect the outer layer of your skin and play a major role in causing skin cancer.
So What Does Broad-Spectrum Protection Mean?
When your sunscreen offers broad-spectrum protection, it safeguards your skin from both UVA and UVB rays. This ensures that you’re shielded from sunburn, aging, and other forms of UV damage.
What on Earth is PA++++?
This system originates from Japan and measures UVA protection. The “+” signs indicate the level of protection, with more “+” signs signifying stronger UVA defense. For example, PA++++ provides excellent protection against harmful rays.
What is Mineral Sunscreen?
Mineral sunscreens use natural ingredients like zinc oxide and titanium dioxide. These physical blockers create a protective layer on your skin, reflecting UV rays away before they can penetrate.
Now What is a Chemical Sunscreen?
Chemical sunscreens work by absorbing UV rays on your skin’s behalf and converting them into heat. This process prevents the rays from causing damage to your skin cells.
