Worst skin care ingredient offenders

Polyethylene glycol, aluminum starch octenylsuccinate, and oxybenzone in antiaging products and sunscreens.

Fragrance and triclosan in makeup, soaps, exfoliants,
and lotions.

Phthalates, parabens, and petroleum in everything from facial wash to moisturizers.

Highly concentrated glycolic acid in peels and antiaging products. Avoid products containing more than 5 percent glycolic acid.

How long does it take for a product to work?

Allow 28 to 35 days, the time it takes the outer skin layer to renew itself, before evaluating. Initial mild irritation is normal and often a sign your skin is detoxifying. But stinging, severe redness, or prolonged breakouts indicate you should stop using the product.
