Absolutely LOVE this toner. My skin is slightly sensitive and this formula NEVER burns my face. Great exfoliation. No tightness or dry areas. Fantastic for the price and just as good or better than name brand or expensive toners. I’m a repeat buyer. Big bottle and lasts a while. I would highly recommend.
