Love the Strong Acid, my skin definitely glows after using it. Don't love the smell though. . . . . . it stinks a bit like vinegar! Also, why does it have to be in such a heavy bottle, that isn't transparent so I've no idea how much is left and when to order the next one!!

I’m loving the strong acid. I was a bit hesitant as I’ve been a control acid user for a long time and thought it may be too much. It’s certainly strong, it gives a tingle and even smells strong (?) but my skin is loving it. No turning back now!

Been an acid user for years so this was my natural progression. Have not had any irritation from this product, having introduced to my routine 2-3 nights per week. Immediately upon using my face glows. My skin is looking fresher and feels smoother. Excellent service as always from SR!
