This toner is my daily go-to for keeping my face in check. It’s gentle on my skin but packs a punch when it comes to keeping my sensitive skin clear and fresh. I use it every morning and night, and my skin has never looked more balanced. It doesn’t sting or dry me out, and it layers beautifully with my other products. Total game changer. I use Thayers Blemish Clearing Toner with the ForPro XL Facial Pads and the combo is perfection. The toner glides on smoothly, and the pads help distribute it evenly without soaking up too much product. My skin feels clean, refreshed, and noticeably clearer. If you’re looking for a refreshing, non-harsh toner to add to your routine that’s simple and effective, this duo is it!

Gentle, yet very effective

Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)

I've used multiple exfoliating toners in the past but none were as effective as this one. I have been using it for 3 days now along with the La Roche-Posay Toleriane Purifying Foaming cleanser and it's cleared the whiteheads on my chin quite a bit and made my face feel and look smooth. Will continue to repurchase.

Finally Something That Works For Me

Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)

Imma be honest - I haven’t had great skin for over 30 years. I feel like like there’s always :something: that makes me resort to only being comfortable wearing make-up any day I have to see people / leave the house. But, I started using Thayers in October 2025 (I created my own “Thayers system”: salicylic toner, salicylic pads, and - at times - the stuff in the little dropper bottle) and I can honestly say that :finally: something is working for my skin! I have tried everything! But Thayers is it for me these days. Thank you!!
