Questions
Asked and answered.
Why is Bleu blue?
The color is the copper. GHK-Cu carries a Cu²⁺ ion that tints the serum naturally — no dye added.
How do I use it?
Two to four drops at night on clean, dry skin. Press into face and neck, follow with moisturizer, SPF in the morning.
Will it fit my existing routine?
Yes. One step, at night, before moisturizer. Everything else stays as it is.
How long does one bottle last?
30 nights at the nightly dose. The guarantee runs the full ninety.
When should I expect visible results?
Texture and radiance typically read first around weeks three to four. Appearance claims only — cosmetic, not a drug.
Is it fragrance-free?
Yes — fragrance-free and dye-free, with the complete INCI printed on every carton and bottle beside the batch date.
Is this a subscription? Can I cancel?
