Awesome!
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
Love this product! I've used witch hazel for a long time as a toner and to help keep acne under control. Thayer's is the brand I've always used and loved. This one is specific for acne and blemishes, so I thought I'd give this blend a try. There is a slight fruit loop smell (it fades quickly!) and I feel like it's slightly sticky (which is not how plain witch hazel feels) but that also goes away as it dries. I use this anywhere on my face, but especially where there are blemishes and acne. It works well, and doesn't seem to adversely react with my rosacea , which is a plus! I let it air dry, then apply my favorite moisturizer. Results come quickly, and I love how clean and fresh and skin feels!

Great Toner!
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
I have both rosacea and acne. I use this to control my acne breakouts, and it never makes my rosacea flare up. It’s really good toner & I highly recommend it. It has never made me have any sort of rash/breakout/reaction.

Works
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
I've had horrible acne issues for the past 2 years since having my daughter. I've tried everything to get rid of it and nothing was working until I tried this stuff! Within 2 days the redness was significantly reduced and I've been having far less issues with my skin. It did cause the skin to purge in the areas I get the most blemishes but that is normal according to Google

This Thayers Blemish Clearing toner is fantastic. It does not have an offensive smell, nor is it abrasive to the skin. Consistent use will see your skin's condition improve.

Pleasant, light aroma, gently affects the skin.
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
It has a pleasant, light scent and feels gentle on the skin, helping to keep it fresh and clear, but I recommend following up with a moisturizer to prevent any dryness.
