Chemical sunscreens and mineral sunscreens differ primarily in their active ingredients and how they work to protect the skin from UV radiation. Chemical sunscreens contain organic compounds (like avobenzone, octisalate, and octocrylene) that absorb UV radiation and convert it into heat, which is then released from the skin. In contrast, mineral sunscreens (also known as physical sunscreens) contain active mineral ingredients like zinc oxide or titanium dioxide, which sit on the skin’s surface and reflect UV radiation away from the skin.
When we’re talking mineral vs. chemical, the key is how they interact with the skin and sunlight. Chemical sunscreens need a few minutes to start working after applying. So, don’t head out the door immediately after applying it. Mineral sunscreens, because they just sit there on the skin’s surface, start working as soon as you apply them.
To sum it up, it’s less about which is “better” and more about how they fit with your skin type and lifestyle. Mineral ones are often recommended if you’ve got sensitive skin because they tend to cause fewer reactions. Chemical sunscreens are usually less noticeable on the skin — fewer white streaks to rub in if that’s your main concern.
