    Post-Retinization, skin will look younger, and the appearance of fine lines, wrinkles, and dark spots may fade and diminish.

    • Slow Release Retinol and Bakuchiol work to make skin look more youthful and supple, decreasing the appearance of fine lines and wrinkles.
    • Tepezcohuite extract provides antioxidant benefits and some studies show it increases wound healing to help protect skin during the retinization process.

I enjoy it.

I got this product at a nice discount when I met one of the founder's in person. I told them I was in the market for a Retinol Serum, and they offered me this. I was a little hesitant because last time I had a microcaps Vitamin A serum it felt a little bit powdery and I could feel it rubbing on my skin. Wasn't the biggest fan of that. But this went on really smooth, felt nice, and it not only has .5% active Retinol but also bakuchiol at 1% and Niacinamide and Yeast Extract. I love that combo. Plus my skin didn't seem to be retinized or anything, but I've only been using it for about 2 weeks so we'll see, I guess. Really enjoying it so far!

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.
