    "So I must tell you my skin used to look really dull and highly pigmented. I came across your products specially having acne scars and spots I thought of going with Retinol Serum and Vitamin C Serum, and now I can't believe how my skin looks. It just boosted my confidence and makes me feel sooo good. Thank you!"

Reviews Summary
Customers say this product has a unique, thick texture that divides opinion. Many reviews mention it feels more like a cream than a serum, with some appreciating its mattifying effect while others find it difficult to spread. Reviews are mixed on skin comfort - some report a smooth finish, while others note stinging sensations. Common feedback includes issues with pilling when layered with other products. Users with oily skin particularly praise its mattifying properties. The texture tends to dry quickly on application, with some noting it leaves a residue. While several reviewers appreciate the skin-smoothing effects, others mention challenges with the product's consistency and application.

    Seems very nice

    This is very thick and hard to blend on its own but with hyaluronic acid serum goes on beautifully. I saw my skin getting better and brighter after about two weeks of using this. Tingles a little if you apply this over broken skin, pimples etc. And tastes very strong and bad if it gets near your mouth. Still, results are so good Im going to keep using this for sure.

    Springs, extremely fatty, does not react well with sunscreen

    I've been using Tretinoin, azelaic acid, and lower concentration vitamin c, but this is my first 30% vitamin c. I have rather tough skin, didn't have negative reaction to Tretinoin or azelaic acid, but this stung on application the whole month I tried it. I accepted this as "no pain, no gain", but other issues made me bin this before the tube was finished: 1. It's extremely "fatty". Not oily, or even greasy. 2. When I applied it and sunscreen over it, it combined to make something so fatty and tough that "chunks" formed that I literally had to scrape off my face, no way to wash it off. Soon after this I had some pimples, which is unusual for me.

    Thank you so much for taking the time to share your detailed feedback, Andre.

    We're truly sorry to hear about your experience with our Vitamin C Serum. This is absolutely not the experience we want any of our customers to have. While many customers use our Vitamin C Serum without issue, we understand that everyone's skin can react differently to high-concentration vitamin C formulations, and tolerance can vary greatly from person to person, even for those with experience using other active ingredients like tretinoin and azelaic acid. The texture and layering concerns you've described are particularly valuable feedback for us. We take your experience very seriously, and we'd love for you to reach out to our askINKEY Team, as we would greatly appreciate the opportunity to understand your experience further and explore how we can support 🖤

    Pills no matter what I do

    Originally tried this to add Vit C to my routine but found it pilled very badly, I tried using it in a different order to my other products but this didn't seem to help. I instead purchased The Inkey List's Vitamin C + EGF Serum instead and found that works a LOT better with no pilling. Maybe this product could be changed to mimic the texture of the other one.

    I'm sure the ingredients etc would work well as the alternative serum does but I just couldn't get it to stay on my skin!

    Hello Hannah,

    Thank you for taking the time to share your feedback about our Vitamin C Serum. We're truly sorry to hear about your experience with the pilling, especially when you were hoping to incorporate vitamin C into your routine. We understand how incredibly frustrating it must be when a product won't stay on your skin properly, no matter how you adjust your application order or routine. This isn't the experience we want for our customers, and we completely understand how disappointing it must have been to struggle with the texture when you were looking forward to the benefits of vitamin C in your skincare routine. We're pleased to hear that our 15% Vitamin C + EGF Serum has worked much better for you without the pilling issues, and we really appreciate your constructive feedback about the texture differences between our formulations. While many customers have experienced smooth application with this formula, we recognise that skincare layering can be highly personal, and different vitamin C formulations may interact differently with various products and individual skin types. We would be grateful if you could reach out to our askINKEY Team if we can support you further with your experience 🖤
