You may not have noticed, but the sunscreen you’re using right now is either a mineral or chemical formulation — and the difference between the two is important to know. The way they work and the way they wear make each type of sunscreen more desirable to some people than others. Find out where you fall in the mineral vs. chemical conversation and discover which best aligns with your skin care needs by learning the benefits and drawbacks of each.
Mineral sunscreen
The two ingredients used to create mineral sunscreen, also known as physical sunscreen, are zinc oxide and titanium dioxide. These mineral-based UV filters create a protective barrier on the skin, reflecting the sun’s rays and shielding you from damage.
Pros
● Takes effect immediately. Since mineral sunscreens create a physical barrier on top of the skin, their UV filters are instantly activated once applied, meaning there’s no waiting time before safely heading outdoors.
● Non-irritating to sensitive skin. Titanium dioxide and zinc oxide are the only two UV filters considered safe and effective by the FDA. These natural ingredients are gentle enough for use on children and are non-irritating, making mineral sunscreens ideal for sensitive skin types like those with eczema or melasma.
● Safe for acne-prone skin. Mineral sunscreens are non-comedogenic, meaning they won’t clog your pores. They also have anti-inflammatory properties which won’t exacerbate breakouts.
Cons
● May be difficult to fully blend in. Mineral formulations tend to be thick and rich, so it may take more effort to spread on evenly.
● May leave a white cast. While formulations have evolved, some mineral sunscreens can be chalky and leave a white residue on skin. This can be more of an issue for those with darker skin tones who may prefer a sheer finish.
● Can rub off when wet. Since mineral sunscreens don’t absorb into skin, you may need to reapply more often when swimming or playing outdoors as they can sweat or rub off.
Chemical sunscreen
The active ingredients typically used in chemical sunscreens — oxybenzone, octinoxate, octisalate and avobenzone — work by absorbing UV rays and transforming them into heat before being released by the body.
Pros
● Lightweight and easily spreadable. Chemical sunscreens are ideal for everyday wear due to their ease of application, blending into skin smoothly and quickly.
● Goes on clear and leaves a sheer finish. Darker skin tones can enjoy chemical sunscreens without any white residue being left behind. Plus, a clear formulation makes them easier to wear under makeup.
● Easier to mix with other products. Combining other ingredients like peptides, antioxidants and enzymes into your sunscreen can offer additional skin-protecting benefits.
Cons
● Takes time to take effect. Chemical sunscreens require approximately 20 minutes to become effective after application before you can safely venture outside.
● May irritate sensitive skin. The multiple active ingredients used in chemical sunscreens may increase the likelihood of irritation, especially for sensitive skin types.
● May pose a potential danger to marine life. Oxybenzone and octinoxate have been associated with coral bleaching. If eco-friendliness is a requirement for your sunscreen, opt for a chemical formulation without these ingredients.
The right sunscreen for you is…
Either! The best sunscreen for your skin will be the one you use most frequently. As long as you feel comfortable wearing it, both mineral and chemical sunscreens offer protection against harmful UV radiation — just keep these tips in mind:
● Choose a sunscreen with an SPF of 30 or higher.
● Pick one that offers broad-spectrum protection against both UVA and UVB rays.
● Reapply it to all areas of exposed skin every two hours, and more frequently if you’re swimming or sweating.
● Wear it every day, rain or shine.
