What's the one skincare ingredient you always try to avoid?

We're launching GlowGuard on July 28 – a browser extension that flags allergens and irritants right on the product page, based on your own skin profile.

While we count down to launch, we're curious: what's your "nemesis" ingredient – the one you always scan labels for? Fragrance? Essential oils? A specific alcohol?

Drop it below 👇 We want to make sure GlowGuard catches the ones that actually matter to real people.
