What I didn’t like:
– not waterproof

Sleek Makeup is one of my go-to brands for eyeshadows and blushes, but mascaras? Not really. Well, that may be about to change. The British drugstore brand has just released a new mascara that lengthens and thickens your lashes while taking care of them. And it’s pretty awesome.

Two coats of I’m Conditional (what a cool name is that?) gives my lashes some volume and lots of length. I didn’t try a third because I thought the mascara made them long enough already. The black colour is very intense too, giving your lashes that naturally dramatic look that gets them noticed in a good, not over-the-top way.

The formula has just the right consistency. It’s not runny, but not thick either, doesn’t clump, and leaves lashes soft. It contains biotinoyl tripeptide-1, a peptide made by Sederma that can, according to the company, condition lashes, stimulate hair growth, and strengthen hair. There is only very little of it here, but it’s better than nothing. With regular use, it may help your lashes grow and make them stronger.

The double bristle, medium-sized, brush easily captures even the tiniest of lashes, making application a breeze. Once on, the mascara lasts for about 9 hours on my lashes. I didn’t experience any flaking but, because the mascara isn’t waterproof, it will smudge if you cry. But at least this makes it easier to remove at the end of the day. You don’t want to spend ages tugging at your lashes to take off every bit of it, do you?

Sleek Makeup I’m Conditional Mascara adds lots of length and some volume to your lashes for a naturally dramatic look. The medium-sized, double bristle brush easily reaches each lash, coating them with a black pigment that lasts for 8 hours. However, it is not waterproof and will smudge if you shed a tear or two.

Looks great, I think we could all just benefit from some extra length:)

I doubt I’ve ever heard a mascara whose formula includes Biotinoyl Tripeptide-1. It is present in a fair few other beauty products such as Beauticontrol’s Replenishing Conditioner for Eyelashes and Brow. My experience with this conditioner has been relatively positive despite it’s funky smell, it did manage to stimulate and maintain healthy eyelashes. I’ll have to give this mascara a go – out of curiosity.

Iram, I think you may like this then. This peptide is not present in a very high amount but could still help lashes grow and make them stronger. In any case, the look the mascara gives lashes is very pretty too.

It really does add a dramatic volume to the lashes but slightly clumps! Very nicely reviewed. 🙂

Gio September 30, 2014 - 7:12 pm

Tips and Beauty, I think the clumps are more due to my inability to apply mascara than to the mascara itself. In any case, combing lashes will eliminate them. 🙂
