Great results when used carefully
This is a strong exfoliating peel, and it definitely works. The milk texture spreads easily and feels controlled, but you can tell right away that this is not a beginner exfoliant. At 15% glycolic acid, it delivers noticeable smoothing and brightness when used carefully. I started slowly and kept my routine very simple afterward, focusing on hydration and barrier support. Used this way, it helped refine texture and made my skin look clearer and more even. When I increased usage too quickly, I noticed dryness, which was a good reminder that this peel needs to be respected. I would recommend this to experienced skincare users who are comfortable with chemical exfoliation and understand the importance of spacing treatments and supporting the skin barrier. It’s effective, but not something to rush or overuse. I used less than the recommended amount and it was still a little spicy for me.

Restored my glow and smoothness in ONE use!
Restored my glow and smoothness in ONE use! I am 47, and I’ve really started to notice my skin losing its natural glow and becoming a bit dull. I decided to try the Prequel Multi-Acid Milk, and I am honestly obsessed. The results were immediate—literally after one use, my skin felt incredibly soft and hydrated. I’ve been using it twice a week, and the difference is night and day. My skin looks much younger, smoother, and that healthy radiance is finally back. If you struggle with any kind of roughness or uneven texture, this is the solution. It completely clears it up. It’s rare to find a product that delivers such fast results without being harsh. If you're on the fence, definitely give it a try!

Excellent product
It’s amazing. Not too harsh but does the trick. I love this product. My face flushes a little but is normal by in the morning. My skin glows like it never did before. It took about a week for me to see an obvious difference in my complexion. I am sold on continuing to use this daily. It’s not as expensive as a face peel or microdermabrasion.

Perfect Statue
Color: Venus - Large Antique, Color: Venus - Large Antique
This Venus De Milo statue is gorgeous. It is very sturdy but not too heavy…….. it appears heavier than it is which I adore since it is a statue. It has an “aged” coloring around the facial features and intricate details which makes it more authentic looking. I love Greek mythology and this piece is a perfect addition to my living room decor. Definitely worth the price.
