The difference between physical and chemical sunscreen

There are two main types of sunscreen: physical and chemical. While each one helps protect skin from UV rays, they also each have their own unique properties and benefits.

The benefits of physical sunscreen

Physical sunscreen, also called mineral sunscreen, sits on top of skin. Most physical sunscreens leave a white or tinted residue on skin, so it takes a moment for them to sink in and become invisible. A few we recommend trying:

• Porescreen SPF 40: Helps blur the look of pores and has a hint of tint to give skin a primer- like effect.
• Skinperfect Primer SPF 30: Primes and smooths the appearance of fine lines.
• Invisible Physical Defense SPF 30: Rather than leaving a tinted residue on skin, this ultra-sheer formula helps prevent a chalky effect.

To identify this type of sunscreen, look for the words “mineral” or “physical,” as well as active ingredients like Zinc Oxide or Titanium Dioxide.

Physical sunscreen:

• Helps protect against UVA and UVB rays
• Starts working immediately upon application – there’s no need to wait before exposing skin to daylight
• Is generally comfortable for all skin types and conditions, particularly sensitive skin

The benefits of chemical sunscreen

Chemical sunscreens use ingredients that absorb into skin and transform UV rays into heat. This type of sunscreen tends to be popular, not only because it feels light, but it’s less noticeable. A couple we recommend:

• Prisma Protect SPF 30: Helps provide hydration and leaves skin looking luminous.
• Dynamic Skin Recovery SPF 50: Helps visibly firm, smooth and protect skin.
• Oil Free Matte SPF 30: Helps prevent shine and skin ageing on oily, breakout-prone skin.

Chemical sunscreen:

• Helps protect against UVA and UVB rays
• Needs time to absorb (15 to 30 minutes) before exposing skin to daylight
• Comfortable for most skin types and conditions
• Is typically more water- and sweat-resistant
