My Go-To Toner After Trying Many Others
Scent: Unscented, Size: 12 Fl Oz (Pack of 1)
I’ve tried many toners over the years, including higher-end brands, and this one continues to stand out for both performance and price. It does exactly what I need without unnecessary extras.
The formula feels gentle and effective, and I really appreciate that it’s alcohol free and fragrance free. Those two things are especially important to me, and this has been the only toner I’ve felt comfortable using during pregnancy. It doesn’t irritate my skin and fits easily into my daily routine.
Despite the affordable price, it performs just as well—if not better—than many more expensive options I’ve used in the past. My skin feels clean and refreshed after using it, without any tightness or residue.
Overall, this is a reliable, no-nonsense toner that delivers great results at a very reasonable price. If you’re looking for a simple, fragrance-free option that works well without breaking the bank, this is an easy recommendation.

Liquid facial magic!
Scent: Coconut Water, Size: 12 Fl Oz (Pack of 1)
I love this stuff. I use it daily as part of my facial routine and it has become one of those products I don’t even think about anymore because it just works.
It smells good without being overpowering and does a great job of helping control excessive oil buildup on my face. Nothing harsh, nothing drying, just clean and refreshed skin. Right after using this, I follow up with a facial moisturizer and the combo works beautifully. My skin feels balanced instead of tight or angry, which is exactly what I’m going for.
I know the label says men can use this as an aftershave, but that’s a hard pass for me. I stick to soothing, purpose-built post-shave products, specifically from Wholly Kaw. That stuff smells like it was handcrafted by skincare deities who truly care about your face. This toner is staying firmly in the “daily skincare” lane, where it shines.
Another big plus is how gentle it is. No burning, no weird tingling, no regret. Just a calm, refreshing step that makes my skin feel like it’s being treated with respect.
And the price? Under $10. That alone keeps me coming back. Honestly, I think they could charge a few dollars more for how well this performs, but I won’t complain about paying less for fantastic facial liquid magic.
Simple, effective, affordable, and a permanent part of my routine. My face approves.

Lasts awhile! Good product
Scent: Rose Petal, Size: 12 Fl Oz (Pack of 1)
Cleans without overdrying. Leave skin feeling clean, no stickiness. Pleasant light scent that doesn't linger. I get my moister from other products so this one idk if it moisturizes by itself. Good value for the money, you get a lot so it lasts awhile.
