Rated 5 out of 5 by from Relaxing Before Bed I received this as a gift and have used it a few times, i have to say I am really impressed, you just put a small amount into the bath and it dissolves quickly releasing a really nice relaxing scent. I tend to use this in a bath in the evening to help relax me before going bed.

Rated 5 out of 5 by from Heaven in a tub I was hooked on the shower gel after getting a small bottle in a M&S advent calendar and have used it ever since. I have now started buying directly from REN and tried this scrub. As I said it is bliss in a tub. Will not use anything else now. One of the best

Rated 5 out of 5 by from SUPER HEALTHY AND DISSOLVES QUICKLY! I've just started taking baths and I wasn't expecting much from this product, but I definitely enjoyed it a lot. The salts dissolve in warm water pretty quickly and I feel very relaxed afterward. I've used it only two times so far, so I can't tell how effective it is but my skin definitely feels better and I was able to enjoy the overall bathing experience a lot.

Rated 5 out of 5 by from Great for a relaxing bath These were a birthday present which I've just got round to trying as the weather is getting cooler and it's time for long soaks again. I don't like a heavily scented bath product or bath oils so this was ideal for me. The salts dissolve quickly and completely to give a relaxing treat.

Rated 5 out of 5 by from This works! I was given the advice to start using bath salts with magnesium by my physician to calm down the muscle tension. And this worked! I use it as prescribed (2-3 handfuls are enough) after a workout or a long-distance walk and feel how my body relaxes... Amazing product, I will definitely be repurchasing it.
