Thanks to Amazon I can order my stuff and get delivery on time and fast 👍👍👍 ### ⭐⭐⭐⭐⭐ Product review *by A***H on 22 May 2026* This serum is very good. It actually hydrates your skin, and one application is enough for the whole day. ### ⭐⭐⭐⭐⭐ "Serum with a smooth texture and light feel — worth every penny! 🌙✨" *by R***W on 21 April 2025* 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. ## Frequently Bought Together - Dot & Key Blueberry Hydrate 12% Barrier Boost Serum with 7 Ceramides Niacinamide Hyaluronic Acid, Reduces Dark Spots, Brightens Skin, Provides Intense Hydration Repairs Skin 30ml - Dot & Key Strawberry Dew Tinted Sunscreen SPF 50+ Pa++++ - 01 Porcelain | Protection Against UA/UB | Broad Spectrum, Water & Sweat resistant | For All Skin Types | 50ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/771694827-blueberry-hydrate-12-barrier-boost-serum-with-7-ceramides-niacinamide](https://www.desertcart.tn/products/771694827-blueberry-hydrate-12-barrier-boost-serum-with-7-ceramides-niacinamide) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
