What the gurus are saying

Gurus are consistently enthusiastic about Lash Clash, praising its ability to deliver intense volume and curl, especially when layered or paired with a lash primer. The brush and formula are highlighted for creating visible fiber and oomph rather than a subtle effect. The product is noted as a top seller and beloved by repeat users for its performance on difficult-to-curl lashes.

"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'm going to use my intense lash combo starting with the Dior lash primer and then we're going to go in with the YSL Lash Clash mascara. I'm going to really layer this up."

"I'm going to follow that up with the YSL Lash Clash mascara. This duo just really packs a punch so I want something really intense today."
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."

"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."
