What is Physical sunscreen?
Physical sunscreen, commonly known as mineral sunscreen, acts like a shield on your skin, bouncing harmful UV rays away. Although older formulations often left a slight white cast, modern advancements have created smoother options, such as those found in our Physical SPF collection.
Pros
- Shields skin from both UVA and UVB rays
- Zinc oxide offers skin-healing benefits
- Suitable for all skin types, including sensitive ones, thanks to its mineral base
- Provides instant protection upon application
- Less likely to block pores or irritate sensitive skin
- Sits on the surface rather than being absorbed into the skin
- Free from chemical ingredients
Cons
- Tends to leave a white cast on the skin
- Often has a thicker texture
- May become less effective during water or sweat-heavy activities
What is Chemical sunscreens?
Chemical sunscreens work by absorbing UV rays into the skin, acting like a sponge to convert these rays into heat, which is then released from the body.
Their active ingredients include oxybenzone, avobenzone, octisalate, octocrylene, homosalate, or octinoxate.
If these components are listed on your sunscreen’s label, it indicates it is a chemical sunscreen.
Pros
- Shields skin from both UVB and UVA rays
- Offers better water and sweat resistance
- Lightweight, non-thick formula for effortless application
- Leaves no white or milky residue
Cons
- Chemical ingredients may irritate sensitive skin and can clog pores more easily
- Needs to be applied 15-30 minutes before sun exposure for optimal effectiveness
- Absorbs into the top layer of the skin instead of sitting on the surface
The difference between physical and chemical sunscreen
Choosing between physical and chemical sunscreen depends on your personal preferences and skin needs, but both can effectively protect you from the sun. According to Dr. David Harvey, a dermatologist, the most important factor is using an SPF of 30 or higher, regardless of the type of sunscreen you choose.
Chemical sunscreen absorbs UV rays into the skin, converts them into heat, and then releases them from the body. Active ingredients in chemical sunscreens typically include avobenzone, octinoxate, and oxybenzone.
On the other hand, physical sunblock works by sitting on top of the skin, reflecting UV rays away from the skin. Titanium dioxide and zinc oxide are the primary active ingredients in physical sunscreens.
