NOT a "dupe" but has the same results.
I am NOT saying this is a "dupe" or that they are the same in any way because they definitely have different ingredient profiles... so don't come for me... But what I will say is that if you like the first aid beauty radiance pads but don't like the price tag then this may be a cheaper option for you. This is my second bottle of this toner and 3rd tub of pads and for me personally they perform the same.
The Thayers is a little stronger of an exfoliant so if you have sensitive or dry skin do a patch test to see how your skin handles it.
I use it in the morning after I wash my face. It gives my skin a nice glow, removes dead skin and anything left over after washing my face and just like the radiance pads helps my makeup lay so much better. I have cotton tissues that are smooth on 1 side and textured on the other that I use instead of cotton rounds.
I pair it with the Thayers milky toner, maybe some other hydrating toners, a serum, a gel moisturizer and always SPF and even without makeup my skin looks amazing and healthy all day.
This is also a 12oz bottle and lasts a long time because you don't need to use a lot for it to do it's job.

Highly recommend for oily skin
The best for oily acne prone skin!! I have tried multiple face cleanses but nothing matches this! My face was broken out and in 2 days I could tell a huge difference. 5 days later my breakout is completely cleared up! Highly recommend using after you remove your makeup and then again the next day before reapplying your makeup! I will be buying again and again for sure

Great product!
I have been using this product for three years and I love it. I use it at night after cleansing with micellar water and before moisturizing my face. I don't think it has an odor, or maybe I am just used to it. I never had any sensitivity to this product and a small amount on a cleaning pad covers face and neck. I am happy with my purchase.
