What do Priyanka Chopra, Kate Bosworth and Victoria Beckham have in common? They all have been known to use a science-backed skincare product so revered for its results that I just had to try out for myself. Meet Augustinus Bader The Rich Cream (from $96; $77), the creamy moisturizer (and viral TikTok product) with a typically hefty price tag. I recently had the opportunity to test this cream extensively—here's why I recommend snagging the holy grail product for yourself, especially while you can get it on *rare* sale!

Developed by Professor Augustinus Bader, one of the world’s leading experts in stem cell research, The Rich Cream is 30+ years in the making. Bader spent the past three decades researching the body’s capacity for self-healing and stem cell regeneration to create his heavily praised skincare line, and based on the brand's clinical trials, it delivers serious results (97 percent of users said it "dramatically transformed" their skin tone and texture). With that in mind, the up-to-$300 non-sale price almost doesn't seem too bad.

But regardless of a discount, it’s not lost on me that The Rich Cream costs more than most skincare products in the average person’s routine. But it’s not just the cult status that makes it worth dropping a huge chunk of change on—it actually provides the results to back up Bader’s 30 years of research.

Upon trying it for myself, my first impression was, wow this product is beautiful. It comes in the chicest royal blue-speckled bottle with a magnetic cap. The packaging sure does feel fancy on my vanity.

Then, there’s the product itself. True to its name, it’s rich. If you’ve ever tried Weleda Skin Food ($19; $15), it’s almost as thick as that, which led me to believe that it might not be great for someone with naturally oily skin. However, when I applied two pumps (in upward motions), my combination skin drank it right up, and left an instant glow that even my mother noticed right away.

I read that it only takes four days to notice a change in your skin, and having tried hundreds of beauty products, I assumed it was a placebo effect if anything. But much to my amazement, my skin was radiant, blemish-free and so much more hydrated after just a few days of use. I even noticed my dark spots fading before my eyes. I have never seen results this quickly from any product I've tested, period—including other pricey serums and treatments I quickly regretted buying.
