Vitamin C: How long do the crystals last?
« on: April 26, 2012, 07:04:53 AM »

I ordered the vitamin C crystals as pre-treatment for needling and dermarolling stretch marks on my hips. I haven't needled for over a year and would like to start needling again. I have stored the vitamin C crystals under my bed in a box, in the plastic bag they came in when I first recieved the order.

Are the crystals active and effective after over a year of sitting under my bed?

Can I still use the crystals as pre-treatment?

Should I order a new bag?

Thanks in advance

The shelf life of vit. C crystals is three years but in reality they will keep even longer.

Vit. C becomes unstable in a watery solution and that is why the vit. C serum has to be made fresh frequently, whereas the crystals themselves are stable.

You should keep them cool, dry, dark, and in a closed container (close the ziplock bag).
