Not for me
This in combination with the aloe-ph balancing face wash was not a good fit for my skin. It had me break out with cystic acne. I went back to Hydro Boost and it cleared up in a week. But that’s for my skin. Also, I didn’t care for the consistency of the product.

A game-changer for oily and combo skin!
Okay, I did not expect to love this toner as much as I do but wow, it completely changed my skin game! The jelly texture feels super luxe and refreshing, and it instantly calms my skin while keeping oil under control all day. My pores look smoother, my skin feels hydrated but not greasy, and it gives that fresh, healthy glow we all want. I’ve been using it morning and night and my complexion has never looked more even. If you have combo or oily skin, this one’s a total gem.
