This mascara is perfect, the wand is so tiny but still places mascara effortlessly on the tiniest bottom lashes. I also noticed my lower lashes don’t stick to my extensions on my top lashes like some I have used so. If you have lash extensions and want nice lower lashes you need this! ### ⭐⭐⭐⭐⭐ Great mascara *by L***A on June 23, 2026* It doesn't clump, it lasts the application wand is way better than normal B ones. Excellent product ### ⭐⭐⭐⭐⭐ A must read! *by S***I on January 28, 2026* I am 52 years old and I had been searching for a good mascara since forever. Yes this one is a bit pricy but it is so worth the money. You will not be disappointed! The wand gets every individual eyelash and does not clump or flake. I was playing around with it and put 3 coats on just to see if it would clump or flake and it did not. I can actually get my bottom lashes easily without getting it all over my skin. I can go on and on about this mascara but you get the point. I will forever and always buy this kind as long as it’s available. 💯❤️ ## Frequently Bought Together - IT Cosmetics Tightline 3-In-1 Lash Primer, Eyeliner & Black Mascara - Lengthens & Conditions Lashes - Ultra-Skinny Wand - Infused With Collagen, Biotin, Peptides & Antioxidants - 0.12 fl oz - IT Cosmetics Superhero No-Tug Retractable Eyeliner - All-Day Wear, Waterproof Formula Won’t Smudge - With Avocado Oil, Chamomile Extract, Vitamin E & Carnauba Wax - 0.008 oz - IT Cosmetics Brow Power Eyebrow Pencil - Universal Shades - Long-Lasting, Budge-Proof Formula - With Biotin - Natural-Looking Brows - Built-in Spoolie Brush --- ## 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.sn/products/1678381-it-cosmetics-tightline-3-in-1-black-eyeliner-primer-lengthening](https://www.desertcart.sn/products/1678381-it-cosmetics-tightline-3-in-1-black-eyeliner-primer-lengthening) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-27*
