Jennir review for Pure Vitamin C21.5% Advanced Serum

This is absolutely my favorite vitamin c product I have tried so far (and I’ve tried the super popular Klair’s vitamin c serum, which I liked but not as much as this one). It has a water-like texture and absorbs pretty quickly. I’ve almost finished my first bottle and it is hands down one of the only products that has visibly, dramatically improved my acne scarring. For instance, I have some fairly old scarring on my upper arms that I thought would never go away (and I was ready to wear long sleeves for the rest of my life lmao) but this serum has made the scarring almost completely disappear—yeah, I was shook too. Overall this product has evened out my complexion so much! I’m for sure repurchasing this again and again.  Recommendations. I think anyone looking for a way to diminish their pigmentation issues and even-out their complexion would see great results using this. I feel like a vitamin c product is a staple in most people’s skincare routines for good reason. This is probably one of the lightest and most affordable formulas you’ll find out there with equally amazing results as something much more expensive. Some warnings though. This is a very concentrated vitamin c product so it can be irritating, like it might cause a tingling sensation or slightly warm burning feeling on first applying it. But this wasn’t a big deal to me as it went away once my skin got used to the product and I think it’s normal with something like this. I personally use this in the morning, usually everyday if I’m not exfoliating or using some other product/ingredient that should not be used with vitamin c (do your research!). I don’t use this at night because I use a retinoid, which you should not use at the same time as vitamin c. If you get any unusual amount of irritation from using this vitamin c serum, check what other ingredients you used at the same time because a lot of ingredients (e.g. ahas/bhas, retinoids, niacinamide) should not be used with vitamin c. Not only will using these things at once probably obliterate the effectiveness of the vitamin c serum, you’ll likely irritate your skin. Also, keep this in the fridge or a cool, dark place and don’t leave it out, sitting open for too long. If she’s left out in the sun or air too long, she’ll oxidize (becoming yellow/orange) and lose potency (aka become less effective). If you can see from my photos, the serum should be clear!
