Mineral sunscreen uses zinc oxide and/or titanium dioxide as its UV filters, while chemical sunscreen uses organic UV filters. Neither type is automatically better. The American Academy of Dermatology (AAD) says both form a layer on the skin that absorbs the sun's rays, and dermatologists recommend mineral formulas for sensitive skin. Mineral formulas can feel thicker and leave a white residue, so choose the one you will apply generously every day.
Mineral vs chemical sunscreen: what is the difference?
The difference is in the UV filters on the ingredient list. A mineral sunscreen, also called a physical sunscreen, uses zinc oxide, titanium dioxide or both. A chemical sunscreen uses organic filters, and a hybrid combines the two; the AAD groups sunscreens into these three types.
The U.S. Food and Drug Administration (FDA) explains that SPF mainly shows protection against UVB, while broad-spectrum sunscreens also protect against UVA. Korean labels add a PA grade for UVA (see the label section below).
| What to compare | Mineral sunscreen | Chemical sunscreen |
|---|---|---|
| UV filters | Zinc oxide and/or titanium dioxide | Organic UV filters |
| How it protects | Mainly absorbs UV, according to the AAD and a 2016 lab study | Absorbs UV, according to the AAD |
| Texture | Often thicker, according to a 2024 review | Varies by formula; read the brand's description |
| White cast | Can leave a white residue | Varies by formula; read the brand's description |
| Sensitive skin | The type dermatologists recommend, per the AAD | Check the ingredient list and patch test |
| Reapplying | At least every two hours (FDA) | At least every two hours (FDA) |
How do mineral filters work: do they block or absorb UV?
You will often read that mineral sunscreen sits on the skin and reflects the sun like a mirror. The sources do not fully agree.
- The AAD says chemical, physical and hybrid sunscreens all form a protective layer on the skin that absorbs the sun's rays.
- A 2016 lab study by Cole, Shyr and Ou-Yang found that titanium dioxide and zinc oxide protect mainly by absorbing UV, not through significant reflection or scattering.
- Health Canada describes mineral filters as "believed to work by scattering and reflecting UV radiation," and some brands, such as ATOPALM, say their mineral filters reflect UV.
So treat "physical" as a name for the mineral type rather than a settled description of how it works. When you choose, the filters and the SPF and UVA rating matter more.
Is a mineral sunscreen better?
Not for everyone. A mineral sunscreen is a good match if your skin is sensitive, because that is the type dermatologists recommend for sensitive skin, according to the AAD.
A chemical sunscreen can be the better pick when a mineral formula feels heavy or leaves a cast you dislike, because sunscreen only protects the skin you actually cover. Both types come with SPF50+ and PA++++ on the label.
What are the disadvantages of mineral sunscreen?
The main trade-offs are texture and white cast. A 2024 review in the Journal of Clinical Medicine explains that mineral-filter sunscreens are often thicker, and that the large particle size and high refractive index of zinc oxide and titanium dioxide leave a white, often unwanted residue.
Some Korean brands answer this with essence-like textures or a tint, as the picks below show. Results differ by formula, so read each description and test a small amount first.
Do dermatologists prefer chemical or mineral sunscreen?
For sensitive skin, the answer is mineral: the AAD says dermatologists recommend physical sunscreens, also called mineral sunscreens, for people with sensitive skin. That advice names a type, not a product, so no single mineral sunscreen is the most recommended for everyone. If your skin is not sensitive, choose by texture, finish and how your skin feels after a few days of daily use.
How to choose a Korean mineral sunscreen for your skin
Each product below lists zinc oxide and/or titanium dioxide and no organic filter in the ingredient list on its Keauty product page. Finish notes are what each brand says. For more options, see Keauty's mineral sunscreen collection, or every type in the sun protection collection.
- Sensitive skin: Complete No-Stress Physical Sunscreen 50ml from AXIS-Y has zinc oxide as its main UV filter in an essence gel lotion texture, and its ingredient list includes no fragrance. Black Rice Pure Mineral Relief Daily Sunscreen Unscented SPF50+ 50ml from Haruharu Wonder pairs zinc oxide with heartleaf extract and niacinamide; the brand describes it as unscented.
- Dry skin: Mineral Skin Barrier Sun Cream SPF50+ PA++++ 50ml from Illiyoon pairs zinc oxide with ceramide NP and panthenol, and its product page says it suits dry and sensitive skin.
- Oily or combination skin: Green Mild Up Sun SPF 50+/ PA++++ 50ml from Dr.G is non-sticky with a matte finish, the brand says, and its product page mentions sensitive skin. Madagascar Centella Poremizing Velvet Finish Sunscreen 50ml from SKIN1004 combines zinc oxide and titanium dioxide with a neutral beige tint and a velvety matte finish; its product page calls it a natural match for oily and combination skin.
- Face and body: Zinc Mild Up Sun Cream SPF50+ PA++++ 65g from ATOPALM lists zinc oxide at 192,000 ppm (19.2%), and the brand says it can go on the face and whole body. Its ingredient list includes essential oils such as sage, patchouli and juniper oil, so patch test first if your skin is sensitive.
| Product | UV filter in the ingredient list | Finish (the brand says) | Good to know |
|---|---|---|---|
| AXIS-Y Complete No-Stress Physical Sunscreen | Zinc oxide | Transparent, no chalky residue | No fragrance in the ingredient list |
| Haruharu Wonder Black Rice Pure Mineral Relief Daily Sunscreen | Zinc oxide | Satin, no sticky or oily residue | Unscented, per the brand |
| Illiyoon Mineral Skin Barrier Sun Cream | Zinc oxide (non-nano, per the brand) | Soft, natural, minimal white cast | Free from fragrance, per the brand |
| Dr.G Green Mild Up Sun | Zinc oxide | Matte, no white cast | No fragrance in the ingredient list |
| SKIN1004 Poremizing Velvet Finish Sunscreen | Zinc oxide, titanium dioxide | Velvety matte, beige tint | One shade only |
| ATOPALM Zinc Mild Up Sun Cream | Zinc oxide (192,000 ppm) | Moisturizing, minimal white cast | Contains essential oils |
Which Korean mineral sunscreens leave less white cast?
The table above lists each brand's own claim, from AXIS-Y's transparent finish to the minimal white cast Illiyoon and ATOPALM describe. SKIN1004 says its beige tint sets without a white cast, but it comes in one shade that its product page notes may not match deeper skin. To check, apply a pea-sized amount along your jawline, let it set, and look in daylight.
What should a mineral sunscreen label say?
- The UV filters. For a mineral-only formula, look for zinc oxide and/or titanium dioxide and no other UV filters. A name that says "mineral" is not proof on its own. Unsure about an ingredient? Ask us.
- SPF. The FDA explains that SPF is mainly a measure of UVB protection.
- UVA protection. A 2025 review in Photodermatology, Photoimmunology & Photomedicine notes that Korean sunscreens show a PA grade next to SPF, while US sunscreens use SPF only. On US labels, look for "broad spectrum," which the FDA says also covers UVA.
- Fragrance and essential oils. For sensitive skin, check for fragrance (parfum) and essential oils such as lavender or sage oil.
What does non-nano zinc oxide mean?
"Non-nano" is a label claim: the brand states that its zinc oxide or titanium dioxide particles are not nano-sized. Illiyoon, for example, says its Mineral Skin Barrier Sun Cream uses 100% non-nano mineral filters, while some ingredient lists add "(nano)" after a filter's name.
Particle size also affects looks: the 2024 review links the large particles of zinc oxide and titanium dioxide to their white residue. If the nano question matters to you, check the label.
When a Korean chemical sunscreen is the better pick
Choose a chemical formula when mineral textures or a white cast keep you from applying enough. A 2025 review notes that Korean sunscreens often use filters such as bemotrizinol and bisoctrizole, and its authors write that these give stronger UVA and UVB protection than filters common in US products, such as oxybenzone and octinoxate.
Examples in Keauty's chemical sunscreen collection include Relief Sun : Rice + Probiotics 50ml from Beauty of Joseon, a light, creamy texture with a natural glow and no white cast, the brand says, and All-day Airy Sunscreen 50ml from Dear Klairs, which the brand says leaves no sticky residue and no white cast. For more options, see our Korean sunscreen guide.
Why do sunscreen rules differ by country?
You may read that sunscreen from Europe or Korea is "better." What clearly differs is how countries regulate sunscreen:
- United States: the FDA regulates sunscreens as drugs and notes that some other countries treat them as cosmetics. It says it added bemotrizinol as a permitted sunscreen active ingredient in June 2026.
- European Union: the European Commission says sunscreens are cosmetics under Regulation (EC) No 1223/2009, and under that regulation a UV filter must be listed in Annex VI to be allowed.
- Great Britain: an opinion published by the UK Office for Product Safety and Standards notes that a new UV filter needs approval and listing in Annex VI of the UK Cosmetic Products Regulation.
- Australia: the TGA says therapeutic sunscreens generally must be in the Australian Register of Therapeutic Goods before sale, while some, such as cosmetic secondary sunscreens, are excluded.
- Canada: Health Canada classifies sunscreens as non-prescription drugs or natural health products, depending on their active ingredients.
This guide explains filters; it does not cover the rules for any single product.
FAQ
What is the healthiest sunscreen to use?
No single sunscreen is the healthiest for everyone. The AAD says mineral, chemical and hybrid formulas all absorb UV, so compare filters, SPF and UVA rating, and pick one you will apply generously and reapply.
Which sunscreen should I stay away from?
Skip formulas with ingredients your skin has reacted to before, such as fragrance or certain essential oils, and patch test any new sunscreen first. Our skin quiz can help you narrow down a routine for your skin type.
Can I use mineral sunscreen every day?
Yes. The mineral sunscreens in this guide are meant to go on as the last step of your skincare routine, and Haruharu Wonder names its formula a daily sunscreen. The FDA advises reapplying at least every two hours.
How often should I reapply mineral sunscreen?
The FDA says to reapply at least every two hours, and more often if you are sweating or swimming. If you wear makeup, see how to apply sunscreen over makeup.
What does PA++++ mean on Korean sunscreen?
PA is a UVA protection grade introduced by the Japan Cosmetic Industry Association. It runs from PA+ (low) to PA++++ (high), so PA++++ is the top grade on that scale.
Keauty sells some of the products mentioned here.
