Vitamin C Suspension 23% + HA Spheres 2%

Has used it for years: a backlit glow no other vitamin C gives them, oxidises less easily and moisturises, but it's potent and not for beginners.

“It makes my skin glow like the setting sun. I have used it for years”

Finds The Ordinary's vitamin C suspension awful and gritty.

“Only thing is I think their vitamin C suspension is awwwful, avoid that. It’s gritty, like someone mixed Emergen-C into moisturizer.”

The Vitamin C Suspension 23% seems to work fine but leaves residue on their hands that won't wash off for hours.

“The product seems to work just fine, but then it leaves residue on my hands that I can't wash off.”

Stronger than The Ordinary's gentler option but works well.

“Vitamin C Suspension 23% + HA Spheres 2% — this one is stronger, but works well.”

They absolutely love the Vitamin C Suspension 23% at night: skin feels brighter almost right away; it stung badly at first, so they mixed it with CeraVe cream.

“I love this product. I hear a lot of bad stuff about it but I absolutely love it.”

TO's vitamin C suspension pilled on them, so they stopped using it.

“I had the same issue with TO’s vitamin c piling and I stopped using it a few years ago.”

The Vitamin C Suspension 23% constantly pills all over their face, whatever amount or layering they try.

“I've been using the Vitamin C Suspension 23% and no matter what I do, it constantly pills up all over my face.”

TO Vitamin C 23% worked well and improved their skin, but the oily, greasy, slow-absorbing texture was so off-putting they didn't repurchase.

“I used TO Vitamin C 23% last year, and I hate to admit that it worked well.”

Mixing TO's 23% vitamin C with Resveratrol/Ferulic a few times a week is really effective for brightening and fading patches, though very grainy and needs rinsing off in the morning.

“I use TO Vit C + Resveratol/Ferulic a few times a week (on non-retinol nights) and find it really effective.”

Under makeup, the TO 23% suspension made their foundation oxidise orange much more; they switched to ethylated ascorbic acid.

“I also felt like the TO 23% suspension when worn under makeup was causing my foundation to oxidize orange a lot more.”

Having built up from a 12% derivative, the 23% L-AA suspension is now no more than tingly for them.

“now find the L-AA 23% to be no more than tingly”

Their new Vitamin C Suspension 23% isn't gritty at all, possibly reformulated, though still a bit greasy.

“I just received the 23% in HA on Monday and it's not gritty at all!”

They like the 23% vitamin C mixed with a drop of aloe gel to dissolve the grit, then blot off the shine before moisturiser.

“I like the 23% vit C. I mix a drop of it with a drop of aloe gel”

The 23% vitamin C makes them look and feel really oily and stings on application, so they use it only at night under rosehip oil and cream.

“I haven't tried the 30%, but I found the 23% makes me look and feel really oily.”

A few weeks into the Vitamin C Suspension 23%: the packaging squirts, and it feels slightly gritty and a little oily going on.

“It does have a very slight gritty feel as you smooth it on, and it feels a little oily.”
