Clean beauty 101: a starter guide.
"Clean beauty" is a marketing term, not a regulatory one — which means a label can read "clean" and still hide things you'd rather not put on your skin. Here's a calm, first-principles guide to the ingredients that actually deserve attention.
First, a quick reality check
Most cosmetic ingredients sold in the U.S. and EU are not going to give you cancer. The dose makes the poison, and the regulated dose in a finished product is usually low. Reading labels is not about being scared of chemistry — it's about being able to swap a moderately concerning product for a better one when the better one is right there on the same page.
That's the entire point of FIBYC, and it's the spirit of this guide.
The seven worth knowing
1. Long-chain parabens (propyl-, butyl-, isobutyl-, isopropyl-)
Synthetic preservatives. Weak estrogen mimics, restricted in the EU, banned for young children. Methyl- and ethylparaben are far less concerning. We wrote a full guide to parabens.
2. Phthalates (DEP, DBP, DEHP)
Used as plasticizers and to make fragrance "stick." Documented endocrine disruptors. Often hidden inside the word "fragrance" or "parfum" on a label. The EU has banned several; the U.S. has not.
3. Synthetic "fragrance" / "parfum"
A legal black box. The single word "fragrance" can hide dozens of undisclosed ingredients, including phthalates, allergens, and irritants. Look for "fragrance-free" or for brands that disclose their full fragrance composition.
4. Formaldehyde-releasers
Preservatives that work by slowly releasing formaldehyde into the formula. Names to scan for: DMDM hydantoin, quaternium-15, imidazolidinyl urea, diazolidinyl urea, sodium hydroxymethylglycinate. Common irritants and IARC-classified carcinogen via inhalation.
5. Oxybenzone & octinoxate (in chemical sunscreens)
Two of the most common chemical UV filters. Both are endocrine disruptors and have been banned in Hawaii, Key West, and several other coastal jurisdictions because of their effect on coral reefs. Mineral sunscreens (zinc oxide, titanium dioxide) avoid both. Worth a deeper look in our sunscreen comparison.
6. Sodium lauryl sulfate / sodium laureth sulfate (SLS / SLES) in leave-on products
Foaming surfactants. Fine in a 30-second shampoo rinse, much more concerning in a face cleanser or anything that stays on your skin. The bigger issue with SLES is contamination with 1,4-dioxane, an IARC-classified probable carcinogen.
7. Talc (in loose powders)
The mineral itself is fine; the historic concern is asbestos contamination from poorly purified talc. Most major brands now use cosmetic-grade talc that's tested clean, but if you'd rather avoid the question entirely, look for "talc-free" makeup — ILIA, Kosas, Aether Beauty, and Jane Iredale all formulate without it.
What to look for instead
The label words that consistently signal a more thoughtful formulation:
- "Fragrance-free" — not "unscented," which can still contain masking fragrance.
- EWG Verified or MADE SAFE certification on the package.
- Phenoxyethanol, sodium benzoate, potassium sorbate as preservatives instead of parabens.
- Mineral SPF — zinc oxide or titanium dioxide as the active sunscreen ingredient.
- Short ingredient lists. Not always — some excellent products are complex — but a 5-ingredient cream is usually easier to evaluate than a 50-ingredient one.
Brands that consistently deliver
These come up over and over again as FIBYC's "safer alternative" suggestions, across multiple product categories:
- CeraVe — dermatologist-developed, fragrance-free, paraben-free, available everywhere.
- Vanicream — built for sensitive skin; one of the simplest ingredient lists in mainstream skincare.
- La Roche-Posay — pharmacy-grade, well-priced, generally clean formulations.
- ILIA, Kosas, RMS Beauty — the "clean makeup" tier — talc-free, fragrance-free, mineral pigments.
- Burt's Bees, Honest Beauty — widely available drugstore options with consistently clean formulas.
- Dr. Bronner's — multi-use castile soap; one of the cleanest body washes on the market.
- The Ordinary — clinical, minimalist serums at unusual price points.
- Blue Lizard, Badger, ThinkSport — mineral sunscreens that score 95+ on FIBYC's scale.
How to actually do this in practice
The reading-every-label approach falls apart somewhere around your third product page. Tools help. The fast version of the workflow:
- Browse normally on Sephora, Ulta, Amazon, Target, wherever.
- Open a product. FIBYC shows the score in about a second.
- If the score is low, the extension shows you a higher-scoring alternative on the same site.
- Click. Done. Move on with your day.
