What does it do?
AHK-Cu is used in cosmetic skincare for regeneration in a single drop. In Seralune, it is the featured active rather than one ingredient hidden inside a crowded blend.
How do I use it?
Apply 2-3 drops to clean skin morning and night, before heavier creams or oils. Patch test first. Finish daytime routines with SPF.
What should I expect?
Expect a gradual cosmetic change: skin that looks smoother, clearer, plumper, or better supported depending on the category. Most people judge a serum after 4-8 weeks of consistent use.
Who is it for?
It is for people who want regeneration and copper peptides and prefer a fragrance-free routine with one active doing one clear job.

FAQ
Can I use AHK-Cu with other serums?
Yes, but start with one active at a time. Layer watery serums before creams and separate stronger exfoliating steps if your skin is sensitive.
Is AHK-Cu medical skincare?
No. Seralune products are cosmetic serums for the appearance of skin and are not intended to diagnose, treat, cure, or prevent disease.
How long does AHK-Cu take to work?
Hydrating serums can look plumping quickly. Peptides and tone-focused actives are usually judged after 4-8 weeks of consistent use.
