The front of a sunscreen bottle is advertising. The back is where the truth lives, and most of us skip it because the font is the size of a grain of rice.
With new filters like bemotrizinol (BEMT) arriving, label literacy matters more than it used to. Here's how we read one, in the order we read it.

Key Takeaways
- A US sunscreen is an over-the-counter drug, so it should carry a Drug Facts panel with active ingredients and percentages.
- Broad spectrum means protection against UVA and UVB. Pair it with SPF 30 or higher.
- A product that names a buzzword ingredient but shows no active percentages is a red flag.
- Directions matter. Reapply at least every 2 hours, and sooner after swimming or sweating.
Start with the Drug Facts Panel
Sunscreens are regulated as over-the-counter drugs, which is why they have a Drug Facts panel instead of a cosmetic-style ingredient list. The first block names each active ingredient and its percentage.
That's where you confirm what's actually inside. If a product advertises bemotrizinol, the panel should list it with a percentage, and the FDA's June 2026 order allows up to 6%.
Check SPF and Broad Spectrum
SPF measures protection against UVB, the rays tied to sunburn. Broad spectrum means the product also protects against UVA, the rays tied to skin aging.
AJMC's dermatology Q&A recommends broad-spectrum SPF 30 or higher. If the front says SPF 50 and the panel or product details say something else, as we saw on two Amazon listings, treat that as a reason to look closer.
Know Your Actives
- Chemical filters: absorb UV light. Examples are bemotrizinol, avobenzone, homosalate, and octisalate.
- Mineral filters: sit on the skin. Examples are zinc oxide and titanium dioxide.
- Blends: many sunscreens mix both types. Neutrogena's Ultra Sheer lists BEMT with avobenzone, homosalate, and octisalate.
Chemical versus mineral is the big divide, and bemotrizinol versus zinc oxide is the clearest example.
Read the Directions
The directions tell you how much and how often. Neutrogena says to apply 15 minutes before sun exposure and reapply at least every 2 hours.
Ultra Violette's directions call for about a quarter teaspoon on the face and another quarter on the neck and chest, and they note the pump doesn't measure an exact dose.
Red Flags We Watch For
- A buzzword ingredient in the title but no active percentages on the listing.
- An SPF number on the front that doesn't match the product details.
- Reef-safe claims. The term has no regulated meaning in the US, which is why reef-safe sunscreens need a closer look.
- Very few ratings and no clear label photo on a marketplace listing.
Where Label Reading Fits in Your Ritual
The Ritual
Find the Drug Facts panel and confirm the actives.
Photo of the label, or the brand page if shopping online.

Look for bemotrizinol in the active ingredients on the Drug Facts panel, with a percentage. The FDA order allows up to 6%.Is reef-safe on a label trustworthy?+
Reef-safe has no regulated meaning in the US, so treat it as marketing. Check the actives instead.Disclosure: The Ritual Guide is reader-supported.
