Acne can be a relentless adversary, leaving behind scars, both physical and emotional. The constant battle to conceal imperfections, the fear of judgment from others, and the toll it takes on your self-esteem – we understand the emotional turmoil that comes with acne.

That's why we've formulated Eurek-A! Our Slow Release Retinol Serum is designed to penetrate deep into the skin, targeting acne. Vitamin A, the key component in retinol, works in tandem with autophagy, the process by which your body cleans up cellular debris that can contribute to acne. Incorporating intermittent fasting and ensuring you get a full 8 hours of sleep can further enhance this process, maximizing the benefits of retinol for your skin.

With every purchase of Eurek-A!, you'll gain access to our Cathartic Care Program. This invaluable subscription provides guidance and support, helping you navigate your skincare journey with confidence.

Don't let acne hold you back any longer.

I’ve been using this retinol serum for a month or so and I love it. My skin is on the drier side since I am in the sun a lot, I also sometimes get blemishes and have large pores in certain areas, this product has helped my skin all around. I’m also a makeup artist so healthy skin is so important to me, and I have even tested this under my makeup and it sat nicely! Try it out! I loveeeee that it’s clean and vegan .
Attached a pic with and without makeup after using!

Lives up to its name :)

I love this retinol serum. I have sensitive skin and have gotten very irritated by other products but this worked like a dream! Fresh and wrinkle free so it’s for me 😊


This retinol serum is my new go to! I'm new to retinol and this was gentle but effective. I had mild peeling which was easily managed with a thick moisturizer. My skin is feeling glowy and healthy, just love it! Thanks Catharsis!

perfect gentle retinol

I LOVE using this retinol as a part of my nightly routine. It's texture is silky, it absorbs quickly, and I've noticed smoother and softer skin just after a few weeks of use. Highly recommend for both new and experienced retinol users!

Fantastic Serum

Gave it a 2 month test drive after looking into the world of Retinol Serum, and this is one of the first I've come across that uses both Retinol and Bakuchiol. I can confidently say after using it for a couple of months as a part of my skin routine (Toner, 2 other serums, Eurek A!, and moisturizer) - my skin definitely feels softer and my lines looked a little tighter.

A Word Of Advice...


Bonus Tips
When using Eurek-A, it's a good idea to follow up with a cream or moisturizer, like Time For Bed.
Use Eureak-A! 2-3 times per week to start with, gradually increasing usage to every night as skin tolerates.

Always use a sunscreen if Eurek-A! is part of your routine!
Remember Your Sunscreen!
Not only does it protect your skin from premature aging, but also cancer and melanoma. No skincare routine is complete without SPF35+.

Yeast Ferment Filtrate

Blended yeast ferment filtrates are filled with antioxidants, amino acids, and nutrients that help maintain skin’s healthy appearance, including that dewy, moisturized skin look. A veritable piñata of skin-revitalizing goodies made just for you.

Brewer's yeast (saccharomyces cerevisiae) is the famous yeast strain that was first recognized to have potential skin benefits.


Niacinamide, also known as vitamin B3, comes with a cornucopia of benefits. One way it helps skin look its best is by diminishing  the appearance of dark spots. It's always great to take your vitamins!

Niacinamide is found in many places, including the human body, vegetables, and grains.
