Gentle, refreshing, and doesn’t dry my skin out!
Size: 8 Fl Oz (Pack of 1)
It’s great for everyday use, especially if you have sensitive or dry skin. The texture is smooth, it rinses off easily, and the scent is light and pleasant. I’ve noticed my skin looks clearer and more even since I started using it. Definitely a great option if you want something simple, gentle, and effective for daily cleansing!

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.

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.
