Producto perfecto que cumple sus expectativas

Nicht grade das günstigste Retinal, dafür 100% wirksam. Nutze schon seit 15 Monate und mittlerweile jeden Abend. Meine Haut liebt die Textur, Wirksamkeit und das Gefühl am nächsten Morgen:)

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.

Excellent!
