I applied this serum daily for like 2 months—skipped a few nights here and there, I’ll admit—but I still didn’t see much change. Maybe it needs more time or works better if you’re consistent… which I clearly wasn’t.

the overall appearance of my skin has improved!! It’s a bit pricey, but I appreciate the science-backed approach.

My skin feels firmer and healthier after just a few weeks of use.

It’s a good serum, but it’s hard to say if it’s really helping with fine lines or other skin concerns.

I didn’t see significant anti-aging results after a month of use.

My sister gave me the OS-01 Face Cream for my birthday, and I’ve been using it every night. It’s lightweight and leaves my skin feeling soft, but I haven’t noticed the anti-aging results she raved about. It’s nice, but I don’t think I’d buy it myself.

The OS-01 Face Cream is hydrating and leaves skin feeling soft, but the anti-aging claims didn’t show noticeable results for me. It’s a nice moisturizer but feels overpriced for the benefits.

Hydrating and light, but no dramatic changes
