incredible product
ant83 — 5 out of 5 stars
After two months of consistent use, I can confidently say the NIOD Copper Amino Isolate Serum (CAIS 3 1:1) is worth the investment, but you have to be patient. Because it has a completely watery, bright blue texture, it sinks into the skin instantly as a first step without any stickiness, though it took about six weeks before I noticed real structural results. While it didn't erase deep wrinkles overnight, it has completely transformed my skin barrier, rapidly calming down any redness and irritation while giving my complexion a plump, bouncy, and incredibly healthy look. The only downside is navigating the routine restrictions since you can't mix copper peptides with strong acids or Vitamin C but the overall improvement in my skin's tone, clarity and resilience makes the extra planning 100% worth it.
