Article Overview
- Mineral and chemical sunscreens both provide protection against UVA and UVB rays, but the way they protect against sun exposure are slightly different.
- This comes down to the UV filter that the particular sunscreen uses, with mineral sunscreens reflecting UV rays and chemical sunscreens absorbing them.
- In this article, we’ll discuss in more detail the differences between mineral and chemical sunscreen so you can choose the right sun protection for you.
What Is Mineral Sunscreen?
Mineral sunscreens (also known as physical sunscreens) are formulated with inorganic UV filters, such as zinc oxide and/or titanium dioxide. These filters work as a protective layer that essentially “blocks” and reflects UV rays.
The benefits of mineral sunscreen include:
- Ingredients are gentle on the skin, making them suitable for sensitive skin
- Photostable formula has a longer shelf life.
- Act as a physical barrier that starts working straight away.
The potential disadvantages of mineral sunscreen are:
- Can leave a white cast on the skin, especially noticeable on darker skin tones.
- Thicker in texture, which can make it harder to rub in.
- Not always water resistant.
What Is Chemical Sunscreen?
Chemical sunscreens, sometimes called organic, use ingredients like avobenzone, homosalate, octisalate, and octocrylene, which work by absorbing UVA and UVB rays to convert them into heat that is released out of the body.
The benefits of chemical sunscreen include:
- Lightweight and easy to layer with other skincare and makeup products.
- Won’t leave a white cast on the skin.
- Can be formulated to be water- and sweat-resistant.
The potential disadvantages of chemical sunscreen are:
- Some formulas may be harsh on sensitive skin.
- Takes time to absorb (around 20 minutes).
- Not photostable, so it can degrade when exposed to sunlight.
Which Is Better: Mineral Or Chemical Sunscreen?
Aside from the difference in sunscreen formulas and the mode of UV protection, chemical and mineral sunscreens can both be formulated to be broad-spectrum and with a sun protection factor of 50+, so the choice is really a personal preference. There are some hybrid sunscreens available that combine mineral and chemical sunscreens to take advantage of both types of UV protection.
If you’re looking for a hybrid, broad-spectrum sunscreen, the SkinCeuticals Ultra Facial Defence Sunscreen SPF 50+ is a hybrid sunscreen that protects against the sun's harmful UV rays while hydrating the skin.*
ALWAYS READ THE LABEL AND FOLLOW THE DIRECTIONS FOR USE.
Apply 20 minutes before sun exposure. Sunscreen is only one part of sun protection so wear protective clothing and seek shade. Avoid prolonged sun exposure. Reapply every 2 hours and after swimming, towelling and perspiring in accordance with directions.
