Extraordinary! Review by BeckyB

At 43 I had resigned myself to large pores. I've used DD's glycolic cleansers, picture porefect and ain't misbehaving for a long time with good results but this toner pushed me into PERFECT skin within 2 days. Absolutely astonishing. Pricey but worth every cent. It has totally changed my self-image. Thanks!

Works wonders! Review by R

I love this product. My skin is visabily smoother and softer. I have very sensitive skin but this product does not irritate me. The best part is that it cleared up blemishes, blackheads and redness and then stopped them from coming back. Definitely worth the price since it lasts so long and actually works! So far im not halfway through one bottle and ive used it daily for two months.

Helps control milia without overdrying Review by Candace C

I am using this product for the milia that I have had all my life, but recently it seems they've gotten worse on my face. They used to be on my upper arms. I wash my face religiously night and morning and use various products for moisturizing that are not heavy or greasy. I think this toner is helping. Regardless of which cleanser I use, I always finish with this toner, and it never leaves my face feeling striped or tight. I've only been using it for a couple of months, but I think it's helping. BTW, I'm 68, so it isn't acne or other conditions associated with puberty or youth.

Love it Review by Mbrewer

I am 30 and still have breakouts. This product is a relief. It has helped control and clear my breakouts in a matter of days. Worth the price!!

Awesome product Review by stacy

I have been using this toner for at least six months and I am still in love. Other products in the past have dried out my skin but I have never had that issue with the Litmus Test replenishing toner. This is a great alternative for adults dealing with hormonal breakouts. I use this in combination with Ain't miss behaving acne serum and the Litmus Test face lotion. What a great combination of products! It may seem pricey but it is well work the money. I also wash my face twice a day religiously and it lasts well over two months.

Love it Review by K
