Yves Saint Laurent All Hours Glow Foundation
Lower concern. Liquid cosmetics rarely use intentional PFAS.
YSL does not claim PFAS-free status. Liquid foundations typically contain no PFAS-linked coatings or water-resistant treatments. No public lab data available.

What’s concerning
Category baseline
cosmetics is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Formaldehyde / VOCs
YSL does not disclose the specific preservative system in All Hours. If the formula uses DMDM hydantoin, imidazolidinyl urea, or diazolidinyl urea (all permitted in cosmetics under regulated limits), it releases small amounts of formaldehyde over time. This is unlikely to cause systemic harm but may trigger contact dermatitis in sensitive individuals.
Source: ATSDR ↗Fragrance allergens and sensitizers
YSL All Hours contains fragrance listed as an ingredient but does not break down specific fragrance molecules. Limonene, linalool, or other common fragrance components may trigger allergic contact dermatitis in susceptible users, particularly on the face where skin is thin.
1,4-dioxane as manufacturing contaminant
Cosmetics containing ethoxylated ingredients (common in emulsifiers and surfactants) may carry trace 1,4-dioxane as a byproduct. YSL does not certify freedom from this contaminant. Levels are typically below 1 ppm in finished products and pose minimal dermal absorption risk with normal application.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Heavy metals
Iron oxides (approved colorants in cosmetics) can occasionally carry trace lead or arsenic as natural contaminants. No recalls or test failures are on record for YSL All Hours. Regulatory limits in the US and EU require testing and exclusion of such contaminants in approved pigments.
Source: FDA ↗Microplastic shedding
Liquid foundations do not contain intentional microbeads. Silicone polymers in the formula are not classified as microplastics. No evidence of particulate breakdown or shedding during use or storage is documented for this product category.
The full breakdown
What it's made of and why it matters
YSL All Hours is a liquid foundation comprising water, silicones, emollients (oils and glycerin), iron oxide/titanium dioxide pigments, and standard cosmetic preservatives. Liquid foundations are chemically simpler than powders and avoid talc-related concerns. The silicone base is inert once set and does not degrade into microplastics or leach into skin under normal application conditions.
The brand's record and disclosure
YSL Beauty (owned by L'Oreal) has not published detailed ingredient sourcing or heavy-metal testing certifications for this product. The brand does not claim cruelty-free or clean beauty status. L'Oreal parent company has faced historical criticism over supply chain transparency but maintains compliance with EU and US cosmetic regulations, which set limits on heavy metals and restricted preservatives.
How it compares in its category
Liquid foundations in this price tier typically use similar silicone or water bases with iron oxide pigments. YSL All Hours does not stand out as particularly safer or riskier than mass-market competitors like MAC Face and Body or Estee Lauder Double Wear. It offers no special certifications (organic, clean beauty, third-party tested) that would differentiate it on safety grounds.
If you buy it
Store below 25°C (77°F) in a cool, dry place to prevent emulsion breakdown and preserve preservative efficacy. Do not apply to broken or severely inflamed skin. Patch-test on inner arm 24 hours before first full facial use to screen for fragrance or preservative sensitivity. Replace every 6-12 months after opening; discard immediately if color separates, odor changes, or texture becomes gritty, as these indicate preservative failure or contamination.
