Brightening and Spot Fading:
Nonapeptide-1 effectively reduces pigmentation caused by sun exposure, pregnancy, or certain diseases, lightens spots and freckles, and evens out skin tone.
Onset Periods:
Studies show that using cosmetics containing nonapeptide-1 continuously for 28 days (one skin metabolism cycle) can significantly improve dullness; some clinical tests show that a more even skin tone can be seen in just 14 days.
Recommended dosage level:
The suggested concentration of nonapeptide-1 in skincare formulations is usually 0.05% - 0.2%.
