## Description

Product Description

Review: "Serum with a smooth texture and light feel — worth every penny! 🌙✨" - I’ve bought almost all the Dot & Key products from the Cica range, Watermelon range, Vitamin C, and now this one too. The serum works well, but you really need to have a toner from the same range to make absorption easier. I apply it at night and use a jade roller or gua sha with it. No side effects so far — I did get a pimple, but that's because of delayed periods. The packaging is a glass bottle, which is nice, but the quantity is a bit low. The texture is milky. I don’t think it provides skin protection, and I don’t use sunscreen with it either. Overall, the product is worth every penny. It’s fragrance-free and very light.
Review: It works. - Absolutely love it. You can feel the change in a week.

Absolutely love it. You can feel the change in a week.

### ⭐⭐⭐⭐ A good barrier repairing serum
*by B***V on 8 November 2025*

Good product. I had a damaged nd weak skin barrier from using a lot of actives. I was using lot of actives like retinol nd benzoyl peroxide to treat my acne but bcz I had weakened skin barrier, none of them were working nd I had more acne. After I started using this product, my skin calmed down nd reduced acne forming just with 4 uses within 4 days. My skin is a lot more less oily and is becoming better. It's very moisturizing, no oiliness when applied, doesn't clog pores, no scent or fragrance nd doesn't irritate your skin. Overall a good product
