What Is The Ordinary Vitamin C 30% & What Does It Do?

Deciem´s Simple Explanation

Vitamin C Suspension 30% in Silicone offers a silky texture on the skin despite the suspension format of the formulation. Due to the volatile silicone base, the product does not impart any powdery feel on the skin. A higher 30% concentration ensures direct exposure to the highly potent Vitamin C. Avoiding the short-lived gritty feeling that comes with Vitamin C Suspension 23%, this is a great option for high potency with a smooth finish.

How and when would I use Vitamin C 30%?

You can use this ideally in the PM, especially if you´re using products that conflict in the morning (see below). However some people will use this in the morning if they’re using acids and retinol in the evening.

This product is a suspension that would be applied after your water-based products. If you´re using heavier creams, this is where it may get a little confusing. Sometimes people are told to use as the last step after heavier creams and sometimes as the penultimate step. Deciem have told people they can do as they wish, whatever works for you personally.

Which Products Shouldn´t Be Used With Vitamin C 30%?

You should avoid using this product in the same routine as the following products:

  • Peptides, Buffet, Buffet + Copper, Matrixyl, Argireline, NIOD CAIS, NIOD CAIL, Hylamide Sub Q Skin
  • Niacinamide
  • EUK 134
  • Direct Acids
  • Retinol
  • Whilst it is not listed as a conflict, Deciem do suggest avoiding Vitamin C, Acids and Retinols in the same regimen.
  • Always check the official Deciem page before using.

The Ordinary Vitamin C 30% Reviews

Let’s hear what some of the moderators of the Deciem Chat Room and the Deciem Addicts have to say about this product. Read all the reviews here and feel free to leave your own comments.

Jen @jam.jar.skingeek says: Out of all the vitamin c’s from the offering, this is the one I got on with the least. Being a suspension I found it tricky to work with and encountered oxidation of product in my pores.  I have replaced it with EAA (Ethylated Ascorbic Acid.

LS says: It makes my skin itch, even a small amount of it so my skin is too sensitive to it.

JC says:  Pros. Brightens and lightens dark sun spots. Improves skin texture overall. Suspension containing VitC powder is water free and stable and it breaks down over time on the skin to deliver results.
Cons. It is gritty because of the powder but that does not last long. Can stain fabric but those are easily removed.  
The product is surprisingly strong and needs to be gradually introduced. Would not use this around eyes or any delicate skin.

More reviews

Just tried for first time. It’s rather gritty and has oily texture so don’t love the feel but gonna try to use it for a bit and see what it does. I have normal skin a bit on oily side.

JW says:  Just got it and used it last night after washing my face with CeraVe. I have orange pigmentation around both eyes. Didn’t get it near the eye, but applied thicker above and along cheekbones, then a thinner layer all over my face. I sleep with satin pillowcases washed every few days. Woke up this morning, my skin was smooth, calm, no redness. Hoping it takes the orange away. (Along with the other products I purchased too)

PM says:  I love it and just reordered it as part of my Black Friday order. It definitely brightens and it’s so easy to apply.


Can Vitamin C suspension 30% in silicone and Buffet be used together in the same routine? We suggest avoiding products contain peptides when using pure Vitamin C in your routine.

Can I use the hyaluronic acid 2% + B5 after the Vitamin C suspension 30% in Silicone?  We’d recommend applying HA 2% + B5 before our VC 30% in Silicone for best layering.

Can I use The Ordinary Vitamin C 30% on its own or after a rose toner? Yes and yes
