Review: No need for extensions! - Hands down the best mascara I've ever used. I saw a brand on Instagram but I don't buy from IG links. So I came over to desertcart and typed in the brand I saw on IG and this popped up. Same packaging. Same description. Just different brand name. They're all the same. I wish i could wear individual extensions but too many of yall are walking around with bald eyelids. And I refuse! So now I wear this daily and it's everything!!! And it does NOT SMUDGE! I suffer from dry eyes so it was difficult for me to wear mascara at all bc I'd rub my eyes throughout the day and it would burn or get smudged. I no longer have that problem with this mascara which is why I can wear it every single day. Total game changer! I even sleep in it sometimes. And I know we shouldn't but I read somewhere that it offers 72 hour wear and they're not lying! I'm living proof. Lol So some nights I do sleep it in and add more in the morning. It's buildable so my lashes just get longer and longer. (Side note: I do wash my face and clean my eyes morning and night so don't come for me. I'm just gentle around my eyes when I want to keep the mascara on...but thats rare.) I get sooo many compliments on my lashes. This mascara gives me the look of extensions but without my natural lashes falling out. 🙌🏾 Lowkey I said I was going to check the ingredients bc i feel like my lashes are now fuller than they were before. I wouldn't be surprised if there's a growth oil in this mascara. Seriously! Love this mascara! Also I read some negative reviews about clumping. That's got to be user error bc I'm on my 4th tube and not a clump in sight. Any mascara will clump if you don't know what you're doing. Brush wand thru lashes slowly to avoid clumping. I'm telling you, this is the one! I need to become an influencer bc I've given this link to sooo many ppl. I need a link of my own. User tip: you must remove mascara with warm water. Sit a wet towel on lashes before removing mascara. It comes off so easily but they must be wet. Or else it will pull out your lashes. Update: I came back to add to my review. I did not check the ingredients like I said I would but my mother just asked me if I've been using a lash serum bc my lashes look longer and fuller. This validates what I said before. I'm not using a serum. I've only worn this mascara every day for the last 3 months and my lashes are indeed growing! If I find pics to make a side by side, I will post another update.
Review: This mascara works! - I love this mascara. It lengthens and thickens my sparse eyelashes. You can actually see them! The seller is very responsive. I had one tube that was not working correctly and they sent me a replacement before I even had sent back the defective tube. Kudos on the product and customer service.

Mascara is great no flaking if I fall asleep with it on still on the next morning, but comes off great with regular makeup remover. And the sparkly tube is added bonus!
