Kypris Moonlight Catalyst Review

Kypris Moonlight Catalyst Review

I mentioned the Kypris Moonlight Catalyst in my post about powerful, pregnancy-safe beauty products, but since then I’ve given it an even more thorough testing and I must say that the results are very convincing.

It’s a lightweight, watery serum (nothing like the rich, creamy serum I reviewed in my previous post) that absorbs quickly and completely into the skin, and despite the name (and packaging) suggesting a product that might be a bit on the “gentle and dreamy” side, it’s actually a very effective exfoliant.

The big player in the Moonlight Catalyst is the enzymatic exfoliant, which is pumpkin-derived. (One of my favourite fast-acting face masks also stars this exfoliant – Peter Thomas Roth’s Pumpkin Enzyme Mask, see review here.) The exfoliant smooths and brightens the skin (great if you’re continually knackered and grey-hued) without the harsh, abrasive action of a manual face scrub, but the serum has also been formulated with some powerful anti-oxidants, skin-reparing vitamins and moisture-boosters so that your skin gets one almighty big overhaul while you’re sleeping.

Now I’m no stranger to acid exfoliants, but never have I been able to tolerate one this effective whilst pregnant – usually if they’re strong enough to make a visible difference, they’re too strong for my skin and I get redness around my nose or on my chin, or I get breakouts. Kypris Moonlight Catalyst didn’t leave any redness, there were no breakouts and, in fact, my skin felt and looked calmer and more balanced. No tightness or uncomfortable stinging sensation, just really bright and fresh skin the following morning. It was a bit of a trouble-shooter, a few times, magically sorting out spots and dry patches and dullness all at the same time!

I’m afraid this is another pricey serum, though you do get almost 50ml rather than the 30ml offered up in most serum bottles. Moonlight Catalyst is £74 at Cult Beauty here* – it’s actually far cheaper, millilitre-for-millilitre, than Sunday Riley’s Good Genes, though not nearly as eye-wateringly potent. I can’t touch Good Genes when I’m pregnant or breastfeeding, even with someone else’s bargepole, not least because hormones make it smell like stale cat’s wee.

Moonlight Catalyst, then: great for those who want renewed, rejuvenated skin overnight, who want effective ingredients that repair and protect as well as brighten and who perhaps want the hit of a serious “anti-ageing” product without worrying about the retinol/pregnancy issue. (Read about that here.) Also a nice alternative to the glycolic acid-based exfoliants out there, if you don’t get on so well with those.

If you’re after that exfoliant hit but without the luxury budget then take a look at the Peter Thomas Roth mask* mentioned earlier; the huge tub lasts an absolute age and the mask works very quickly, so no hanging about in tepid bathwater waiting to rinse it off…

    My skin is playing up at the moment so, I for sure will be checking this out!

    I have been meaning to get this ever since I saw the bottle, I am relieved to hear that it is not only the packaging that convinces.

    So interesting. I have this serum and want to love it so badly. However, whenever I use it I get breakouts. Might be that I am using too much, glad to hear you had a good experience!

    This is a great review! Ruth, have you tried the Vitner’s Daughter serum that ITG and Stephanie Nicole really love, it’s also supposed to be an “active” serum oil that’s more natural and I’d love to hear your thoughts on it. I lean more natural when it comes to my moisturizers, but not really serums. I’ve also been looking at the Yuli Cell Perfecto PM which is an active night oil that’s from a niche organic brand in America, but that one may be hard for you to source. It’s on a lot of organic American blogs!

    How often do you recommend using a leave on exfoliant?

    • April 8, 2017 / 8:43 pm

      I’ve been using this twice a week. I think you could get away with slightly more, on this one – some people use them every other day, or even every day, but I find this too much. x

    Have not tried an exfoliating serum yet but I think I should. This brand though is not available near my place. Great review.

    This seems like an excellent product for days you don’t want to use something more potent. I’d also like to know your opinion on Vintner’s Daughter and the Yuli Liquid Courage if you ever come across them. I keep reading about them everywhere!

    On a side note, I can’t believe you manage to blog with two babies. I’d probably be passed out all the time. x

    I wish it wasn’t so expensive! It sounds lovely!

    I am obsessed with exfoliating products but haven’t tried something like exfoliating serum, will surely do now.

    This looks like a great product specially for those flaky skin types, but little expensive for some.
