Physical and chemical sunscreens work in different ways to protect your skin from UV radiation.

Physical sunscreen, also known as mineral sunscreen, contains mineral-based ingredients like zinc oxide or titanium dioxide. When applied to the skin, these ingredients sit on the surface and reflect UV radiation away from the skin, acting as a physical barrier. Physical sunscreens are generally considered safe for sensitive skin and provide immediate protection upon application. However, they can feel heavy or leave a white cast on the skin.

Chemical sunscreen, on the other hand, contains organic compounds that absorb UV radiation and convert it into heat energy, which is then released from the skin. Chemical sunscreens are usually easier to apply and do not leave a white cast. However, they can be irritating to some people with sensitive skin and take about 20 minutes to fully absorb into the skin before becoming effective.

It is important to note that both physical and chemical sunscreens can effectively protect your skin from UV radiation, but they work in different ways. Choosing the right sunscreen for your skin type and activity level is important for maximum protection. If you have sensitive skin or are unsure which type of sunscreen to use, it’s always best to consult with a dermatologist.
