A solid vitamin c

Having tied a few different brands of vitamin c this is definitely one of the better products I’ve used. A little goes a long way. And you definitely notice an improvement in the skin looking more radiant and glowing

Beautiful Serum

I brought this on the recommendation from an aesthetic doctor and it doesn’t disappoint. Beautiful consistency and absorbs well.

Takes ages to absorb.

I'm disappointed with this as it leaves my skin greasy. I think it's probably best to use this on a night, but I can't as I use retinol. (Don't mix too many actives ladies!) The search for a non greasy vitamin C serum continues.

great for the price!

The price is amazing for a Vitamin C, I really enjoy using it and I don't know if it is placebo but I already see that my face is brighter. I love using vit C in my routine and I think I would definitely repurchase this. It does smell quite funky but that is normal and to be expected, unless there are added scents to mask it, and I'm glad this one doesn't have added scents. It definitely doesn't linger anyways, the scent is gone within a second of putting it on your face. I suspect with the high concentration of ascorbic acid in here, this will go bad fairly quickly in 2 months or so, but that is always the caveat with potent vit C serums unfortunately. It says to keep in the fridge and honestly after a few days I just gave up on that, because I kept forgetting to use it instead haha. Seems to be doing fine now, but hopefully doesn't degrade in a month :)

Serum has a slightly oil texture but absorbs very quickly and a little goes along way. Pleased with is product definitely smoother skin and evens skin tone.
