physical vs chemical sunscreen

Here are the facts you need to choose the best sunscreen for your skin.

  • Physical sunscreen uses minerals that sit on top of skin and reflect away UV rays.

  • Chemical sunscreen uses ingredients that absorb and transform UV rays into heat.

Understanding Sunscreen Basics

Before we dive into the specifics of physical and chemical sunscreens, let’s start with some fundamental concepts. Sunscreen is a vital component of skin care routines, offering protection against harmful UV rays from the sun. Regardless of the type, the primary goal of sunscreen is to shield the skin from sun damage, which can lead to premature aging, sunburns, and even skin cancer. 

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.

PHYSICAL SUNSCREEN

how it works

uses minerals that sit on top of skin and reflect away UV rays

ideal for

all skin types and conditions, including sensitive; post-treatment SPF

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:

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

CHEMICAL SUNSCREEN

how it works
uses ingredients that absorb and transform UV rays into heat ideal for most skin type

ideal for
most skin types and conditions; active lifestyles

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:

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
