Gentle Fragrance free Non-greasy Gel Cleanser
Size: 8 Fl Oz (Pack of 1)
I bought this for my two teenage sons. I tend to lean towards more natural products. It's challenging to find affordable effective products that not loaded with all the additives and chemicals. While all the ingredients may not be completely "all natural" it is gentle and effective.
My oldest has been using this for about 6 months and has had great results so far. He has already went through an entire bottle and asked for more. It does help keep his face well balanced and his break outs under control.
It is a fragrance-free non greasy gel cleanser with a thin consistency. I got a good discount by purchasing two which is a great value for this product since it is already a decent price for what you get. My family also uses the Thayers witch hazel, milky cleanser, and milky toner and they are all great. We have some sensitive skin types in our family and Thayers does well with sensitive skin types including this Ph balancing cleanser.

Soo good!
Size: 8 Fl Oz (Pack of 1)
Love this product! Im so greatful to have found this through Nina Pool (thank u Nina!) After trying multiple different face washes that left my sensitive skin feeling tight and irritated, im so glad to have tried this one. It's a gel like consistancy thats gentle, hydrating and leaves my face feeling softer and cleaner than any other product ive tried. Ive ordered this product many times. I hope they never discontinue this.

Best Facewash
Size: 8 Fl Oz (Pack of 1)
Favorite face wash ever. No harsh smells or 'chemically' feel. Creates a nice bit of suds and leaves your skin feeling soft and really clean. Compared to other face washes, it is not too expensive for a great product.

Been using this cleanser for over a year now and I love it that it doesn’t strip my skin while leaving it still clean! Super gentle and no fragrance.
