In just a few weeks, my skin looks younger. Apply nightly, wake up with soft, smooth skin. No irritation. Paraben & fragrance-free is a plus.

I've tried many anti-aging serums, but this Kiehl's one stands out. The micro-dose of retinol is genius. It's gentle enough for daily use, and I've seen a visible reduction in wrinkles. My skin tone is more even now, and it has a healthy glow. The addition of ceramides really helps with keeping my skin hydrated. I'll definitely repurchase.

I started using this serum a few weeks ago, and I can already see a difference. My skin is more hydrated, and the fine lines around my eyes are less noticeable. I like that it's suitable for all skin types. I have normal skin, and it works great for me. I'm looking forward to seeing more results with continued use.

The Micro-Dose Retinol Serum has made my skin look younger in just a few weeks. I apply it every night after cleansing, and in the morning, my skin feels soft and smooth. It doesn't cause any irritation, which is great. I also like that it's paraben-free and fragrance-free. It's a high-quality product that delivers on its promises.
