Review: A powerful Retin-A alternative that my sensitive, post-menopausal skin can actually tolerate - I’m 52 with post-menopausal mature skin, and while I’ve used prescription Retin-A in the past, it always ended up being too irritating for me. I eventually switched to Arazlo (which is amazing), but my insurance stopped covering it — and paying hundreds of dollars out of pocket just isn’t realistic. So I decided to try Medik8 Crystal Retinal, and I went straight for the strongest version (20), since it’s considered just one step below prescription-strength retinoic acid. I honestly wasn’t sure what to expect, but I’ve been pleasantly surprised. First, the tolerance: Even at level 20, I’m experiencing no irritation — no peeling, no redness, no dryness. The formula feels creamy and elegant, not harsh or stripping, which makes it worlds easier to incorporate consistently. Second, the results: After consistent nightly use, my skin looks noticeably smoother and more refined. Fine lines look softer, the overall texture looks more even, and everything just feels firmer and more resilient. It truly performs like a high-strength retinoid without the usual misery. The only downside: The color is VERY yellow — almost startling at first. The higher the concentration, the deeper the color, so level 20 is intense. But since it’s a nighttime product, it really doesn’t matter, and it hasn’t transferred to my pillow. If you’ve struggled with irritation from Retin-A or can’t justify the cost of prescription options like Arazlo, this is an excellent alternative. Strong, effective, and surprisingly gentle on sensitive, mature, post-menopausal skin. I’m genuinely impressed.
Review: Great product. - I have used other creams and they were either harsh or did nothing. This one, so far, is fantastic. It is light, soft, smooth, absorbs quickly, and there's no scent. I've been cleansing my face, applying the cream and following the directions. You can feel and see the difference within weeks. Your skin feels and looks tighter, firmer, evens complexion and leaves your skin soft, it helps to minimize fine lines in a few weeks. Highly recommended.

### ⭐⭐⭐⭐⭐ A powerful Retin-A alternative that my sensitive, post-menopausal skin can actually tolerate

### ⭐⭐⭐⭐⭐ great
*by H***F on December 30, 2025*

tret 0.05% was too harsh on my skin (even altreno, which people said was gentler). turned to this instead. it made my skin soooo nice - clear, even, smooth. i'm using this mostly preventatively (early 30s, light wrinkles) so can't say much about anti-wrinkle effect, but it helps with the random blemishes i still get. i can go make-up free thanks to this
