Skinstitut Vitamin C 100% Questions & Answers

You should not. It contains activated material that may cause harm when expired.

thanx

There's no expiry date. Mine is super old but kept well sealed and is still powder. Says if it clumps break up with a fork. Ingredient list is 100% Ascorbic Acid

Thank you for getting back. :)

You must keep it in a dry cool area, Bathroom is a no no. It will keep in an airtight container. Best way to use is: 20% of the cream amount, Put the Vitamin C on the palm of your hand with the cream and mix with your finger. This way you don't have to keep it in the fridge. It's fresh. I mix mine with Invite vitamin E.

can I jist check....my vitamin c was stored and forgotten about . its a little clumpy and 12 months out of expiry...can I still use it?

Did you make it up yourself? You need to keep it refrigerated and a new batch made fresh every 2 weeks. I assume you have bought it. You are better off making your own, it works out a lot cheaper and fresher. You can buy the powder vit C Ester online. Mix. 3 tsp of pure Aloe Vera, 1 tsp 99% pure vit E cream 1 tsp vit C Ester. Mix thoroughly.

No I did not make it myself I bought it from a salon. It is in a tub and as I said the gradual shave compacted and is very hard to shake out through the holes. It is Skinstitute 100% Vitamen C

you can mix both together. Up to 20% vitamin C ester.20% pure vitamin E cream and 60% pure aloe vera gel.Mix enough to last up to 2 weeks. Definitely keep in fridge. Do not use a clear container. You will have to purchase C ester online. It's the better one!

Good luck!

I found it all tò difficult. The c turned everything yellow. I havent used it again

HI,

you should never use anything over your eyelid as the skin there is very fine and ultra sensitive. I would say it's the Retinol rather than the C.
