Safety Warning For external use only Review: Calms my acne/blemish, great delivery - Bought this from cult beauty previously so I knew what to expect, though this time I bought it from desertcart since it was a tad cheaper when taking CB’s shipping fees into account. It’s a great serum that does last a long time. Surprisingly, I also saw a difference the day after I used it - it was honestly a gamechanger and now I’m hooked on it. If you also struggle with regular acne, this might be great for your skin too. It doesn’t necessarily get rid of it but it does calm it down although you may want to do a patch test before using it all over your face. I used a cosmetic analyser to see if there were any harmful ingredients inside and I didn’t spot anything damaging unlike most skincare products so this was an easy repeat purchase. It came packaged well and in its original packaging, nothing leaking or faulty so delivery was great. Highly rec Review: Works super well but can dry you out - My blemishes/red spots calm right down the morning after I used it. Have used it on several nights now and it works! The downside is that I can be quite drying so I would only use it as targeted treatment areas, or as an alternate day regime. Great value for money. I have combination skin and have breakouts on my T-zone and cheeks ## Features - TARGETS BREAKOUTS - This overnight gel treatment targets breakouts, unclogs pores and reduces the appearance of redness by morning - POWERFUL INGREDIENTS - Its powerful combination of Vitamin C and Vitamin E helps reduce the bacteria count on your skin, helping prevent and reduce blemishes; 2% Salicylic Acid also helps to exfoliate and unclog pores, while Lotus Extract helps to balance oil - FOR ALL SKIN TYPES - Suitable for those with oily skin, it is cruelty-free and fragrance-free - HOW TO USE - To be used in the PM as your last step before sleep; Follow your usual skincare routine, but replace your moisturiser step with this night treatment to help reduce and prevent breakouts; Apply a thin layer to the face and neck; It can also be used on other blemish-prone areas, including your back and chest; Once absorbed leave to work overnight and wash off the next morning ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Y5VF1Y7 | | Active Ingredients | glycerin,phenoxyethanol,propanediol,salicylic acid,sodium hydroxide,sunflower seed oil,tocopherol,vitamin c,vitamin e | | Benefits | Anti-Acne, Even Toning, Redness Removal | | Best Sellers Rank | 22,655 in Beauty ( See Top 100 in Beauty ) 277 in Face Treatments & Masks | | Brand | The INKEY List | | Brand Name | The INKEY List | | Customer Reviews | 4.4 out of 5 stars 582 Reviews | | Global Trade Identification Number | 05060422296592, 05060422297292, 05060879822528, 05060879822580, 05060879822597 | | Item Form | Oil | | Item Type Name | The INKEY List C-50 Blemish Night Treatment to Reduce Breakouts and Blemishes 30ml | | Item Volume | 30 Millilitres | | Manufacturer | Be for Beauty | | Manufacturer Part Number | BE00407 | | Material Features | Cruelty Free RAW, Fragrance Free | | Material Type Free | Fragrance free | | Model Number | BE00407 | | Number of Items | 1 | | Product benefits | Anti-Acne, Even Toning, Redness Removal | | Recommended Uses For Product | Pores | | Scent | Fragrance free | | Scent Name | Fragrance free | | Skin Tone | All | | Skin Type | All | | Skin type | All | | Special Ingredients | Salicylic Acid | | Special ingredients | Salicylic Acid | | Target Use Body Part | Face | | Unit Count | 30.0 millilitre | | Use for | Face | ## Product Details - **Brand:** The INKEY List - **Item form:** Oil - **Material Type Free:** Fragrance free - **Material feature:** Cruelty Free RAW, Fragrance Free - **Product benefits:** Anti-Acne, Even Toning, Redness Removal - **Scent:** Fragrance free - **Skin type:** All - **Special ingredients:** Salicylic Acid - **Use for:** Face ## Images ![C-50 Serum 30ml, Blemish Night Treatment, Unclogs Pores, Fragrance Free, Suitable For All Oily Skin - Image 1](https://m.media-amazon.com/images/I/61J4+qka3TL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the vitamin C percentage?** A: Hello... 5% STAY-C 50: Prevents and reduces the look of blemishes and breakouts. 2% Salicylic Acid: Gently exfoliates removing dead skin cells and unclogging the appearance of pores.
