Where I think a toner can be useful is in the form of a leave-on exfoliant . Even if your cleanser claims to be exfoliating, you do wash that off, so there’s a limit to how much good it can really do, and physical scrubs aren’t for everyone. Personally, I love something like Glossier Solution or Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant just to slough off any dead skin cells or residual grime, and give my skin a little extra pep. Plus, I don’t think many of us are as good at washing our faces as we think we are, and by that I mean that if you take the time to wipe a cotton pad over your face post-cleanse, you might be surprised to find there’s a fair bit on there. That includes cleanser! It’s actually harder to rinse off all your cleanser than you’d think, unless you’re doing Neutrogena ad splashes every night, and if you are, man, your bathroom should probably have a slip hazard sign.
