The 'free from' movement turned several routine cosmetic ingredients into villains without strong scientific basis. Some claims have merit; most are marketing positioning that adds nothing to your skin and often costs you formulation quality.
'Paraben-free'
Parabens are preservatives. The 2004 study linking them to breast cancer didn't survive scientific scrutiny — sample size of 20, no control group. Major health authorities (EU, FDA, UK MHRA) confirm parabens at cosmetic concentrations are safe. Brands replaced them with phenoxyethanol, formaldehyde-releasers, or 'natural' preservatives that are often worse for sensitive skin.
'Silicone-free'
Silicones (dimethicone, cyclomethicone) sit on skin and improve texture — they don't penetrate. The 'they suffocate skin' claim is biologically wrong. The actual case against silicones: they create slip that makes silicone-based makeup primer-and-foundation combinations slide. Replacement ingredients are often worse for the same problem.
'Sulphate-free'
In shampoo, sulphate-free formulas matter (curly hair, sensitive scalp). In facial cleanser, the case is weaker — modern sulphate-containing cleansers (CeraVe Foaming) are well-buffered and don't strip skin. Sulphate-free cleansers often use cocamidopropyl betaine instead, which has a higher contact allergy rate than sulphates.
'Fragrance-free' — the one that genuinely matters
Fragrance is the most common cause of cosmetic contact dermatitis. 'Fragrance-free' is the one 'free from' label worth seeking out, especially for sensitive skin, retinoid users, or anyone with eczema or rosacea. Note 'unscented' isn't the same — it can contain masking fragrance to hide ingredient odour.
Most 'free from' claims sell marketing positioning rather than skin benefit. Read what's in the product, not what's been theatrically removed.
