Sample excerpts from currently available source material used in this product analysis.
"THE best Vit C Serum yet. I've tried out a lot of Vit C serums and find this one super powerful - its NOT FOR SENSITIVE SKIN in my opinion. You can feel the acid nip on application its got a whacking 30%. This removes dead skin, encourages..."
"I have very sensitive skin and thought I'd try this. Have had to stop using as it feels like I've rubbed nettles into my face leaving me with painful stinging. I'm not sure why as I use the other products with no problem at all."

How does The INKEY List 30% Vitamin C Serum to... score?
Detailed score breakdown and key findings from our analysis of 15 reviews across 1 source.
Pros
- +Anhydrous silicone suspension prevents L-ascorbic acid oxidation, keeping the vitamin C active and shelf-stable
- +Effective brightening and skin-tone evening reported by users who can tolerate the concentration
- +Fragrance-free and cruelty-free
- +Budget-friendly price point compared to high-concentration LAA competitors
- +Non-greasy, non-oily finish on skin for those compatible with silicone bases
Cons
- -30% L-ascorbic acid exceeds the clinically optimal range (15–25%) and significantly increases irritation risk without added benefit
- -Silicone (dimethicone) base causes pilling when layered with other products and leaves a slimy texture many find unpleasant
- -Consistent reports of chalky/gritty texture, metallic odour, and product congealing on skin
- -Packaging poorly designed — prone to air ingress (accelerating oxidation) and difficult to dispense consistently, leading to wastage
Best For
Watch Out
- !Not suitable for sensitive, reactive, or rosacea-prone skin — 30% LAA causes significant stinging and barrier disruption
- !Dimethicone base pills under most moisturisers and SPFs — use on completely bare skin or test layering carefully
- !Metallic/chemical odour is inherent to the formulation and not a sign of spoilage, but many find it off-putting
- !Increased photosensitivity — SPF is non-negotiable when using this product
- !Hands may temporarily discolour orange if excess product contacts them — a sign of oxidation on contact with air
