How to Measure Your Dosage Most AHK-CU serums come with a dropper or a spray, which makes this easy
Its ability to improve skin health makes it an essential addition to any skincare routine
Face serums and creams: Clinical standard: 1-3% concentration Maximum typically used: 4% concentration Application: Once or twice daily Duration: Minimum 8-12 weeks for visible results Eye area products: Concentration: 1-2% (lower for sensitive periorbital skin) Application: Once daily, typically evening Amount: Pea-sized for both eyes Scalp solutions for hair: Concentration: 0.5% solution common Application: 1-2ml to affected areas once or twice daily Duration: 3-6 months minimum for meaningful changes Higher concentrations do not always mean better results with topicals
If you have sensitive skin, start every other day and increase only if your skin tolerates it
The exact formulation is determined by your skin type, pigment depth & skin sensitivities
A 12-week trial in 71 women with photoaging showed measurable increases in skin density and thickness, reduced laxity, and improved fine line and wrinkle depth with GHK-Cu
