So in this article, we explain the differences between physical and chemical sunscreen, and in addition we offer the most important tips for choosing the ideal product, with a list of ingredients it is advisable to avoid.

The difference between physical and chemical sunscreen

Physical sunscreen

• Contains natural ingredients such as zinc oxide and titanium dioxide.
• Works as a shield that reflects sunlight away from the skin.
• Very suitable for sensitive skin and less likely to cause irritation or allergy.

Chemical sunscreen

• Contains ingredients such as oxybenzone and chemical compounds that absorb ultraviolet rays.
• Prevents the rays from penetrating the skin by absorbing them.
