    "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.

    Very Good

    It's great for what it is, but it would be great if there are some additional active ingredients that works well with Vitamin C.

    Sticks to skin and does not spread

    This product is very disappointing, when I put it on my skin it immediately turns into a paste that is impossible to evenly spread over face, it collects in clumps, impossible to layer with other products and pills on its own even without anything on top.

    Thank you so much for taking the time to share your honest feedback about our Vitamin C Serum, Oksana.

    We're truly sorry to hear about your experience with our product, this is absolutely not the experience we want any of our customers to have. We completely understand your frustration with the texture issues you experienced - the clumping, difficulty spreading, and pilling problems you described must have been particularly disappointing when trying to incorporate the serum into your skincare routine.

    While many customers use our Vitamin C Serum without issue, we understand that product texture and application performance are fundamental to delivering the quality experience our customers expect and deserve. We recognise how frustrating it must have been to deal with a product that wouldn't spread evenly or layer properly with your other skincare products, especially when you're trying to achieve the best results from your routine.

    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 🖤

    My skin couldn’t handle it

    Unfortunately, this serum just isn’t for me. It feels a bit too harsh on my skin, leaving it irritated and itchy. I’m sure it might work for others.

    My skin can easily tolerate 0,1% tazarotene every night, but this serum is simply too much

    Thank you so much for taking the time to share your honest feedback about our Vitamin C Serum, Sara.

    We're truly sorry to hear about your experience with our product, this is absolutely not the experience we want any of our customers to have. We completely understand your frustration with the irritation and itchiness you experienced - this must have been particularly disappointing, especially given your skin's tolerance to other active ingredients like tazarotene.

    While many customers use our Vitamin C Serum without issue, we understand that everyone's skin can react differently to skincare formulations, and sensitivity can vary greatly from person to person. Vitamin C can sometimes be more reactive for certain skin types, even when the skin handles other actives well, and we completely understand your decision to discontinue use after experiencing these issues.

    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 🖤
