What the gurus are saying

This mascara earns consistent praise for delivering serious volume and curl, especially when layered or paired with a lash primer beforehand. The brush is notably large, which creators love for reaching and separating lashes but note can feel a bit messy in application. One dermatologist uses it as a base layer under black mascara rather than alone. Most who reach for it do so precisely because they want dramatic, statement lashes, not a subtle finish.

"This is from YSL. It's a little travel size of Lash Clash. I've loved Lash Clash forever. Isn't this mascara so good by the way? Look at that. I was so happy to get this. This was like in one of my Sephora orders and I was like yes. I love a travel size. I love bringing it back. Reminding me why I love YSL Lash Clash so much."

"I always start off with YSL's Lash Clash in the number four blue. I look a bit whackadoo because I'm too pale to use it, so then I go in with a black mascara on top."

"The YSL Lash Clash Mascara is a beefy mascara. The wand is so huge so it can get a little messy, but it's the combo I'm wearing on my lashes today, paired with the Dior lash primer. It was one of my favorite combo discoveries thanks to Nikki and Lisa, and I'm so glad I picked it up."

What I Bought at Sephora... Uh oh 😬
"The lash primer is on now we'll apply that same mascara. Wow, my lashes feel so curled. I'm pretty sure it was the primer that kind of set the stage but wow, my lashes feel very very curled."

Full Face of NOTHING NEW: GRWM!! 😘
"I'm going to layer up the YSL Lash Clash Mascara. With all this eyeliner I wanted quite a bit of mascara, so a voluminous mascara too, and I felt like this one would be perfect especially when paired with the lash primer."

"This is YSL Lash Clash. I like the brush. I like that it gives you fibers and oomph. I need oomph. I don't want discreet mild lashes. What is the point?"

"I'm YSL Lash Clash. I want full, as we would say up north, I want full slag lashes."

"YSL Lash Clash, as always. These are both dried up, I wouldn't be surprised if the Sahara Desert fell out of this. I need volume and bristle. I don't want just a sleek mascara. My eyelashes are like shop shutters. I need them curled, and then I need to go in quickly with waterproof. I love both of these. I use them all the time."
Chats with C: Suzy Griffin Dunne - Founder of Hildun Beauty | Caroline Hirons
"Probably the YSL Lash Clash Mascara, on my lashes as we speak, waterproof, and it's the number one seller in YSL and Harrods generally. I'll go to the beauty counters and my first question is always what's your number one seller, and she said Lash Clash, yeah, can't keep it in stock."
