    The SkinPeptide Stack

    Three peptides. Three mechanisms. One clear picture of how modern skin repair, regeneration, and radiance actually work — grounded in the same protocols PepPal's assistant is built on.

    01
    Anti-Inflammatory Tripeptide

    KPV

    What it is

    KPV is a tiny calming peptide. On skin, it quickly reduces redness, puffiness, and irritation — think fewer flare-ups, less angry-looking breakouts, and a smoother, calmer complexion.

    How it functions

    It flips off the skin's main 'inflammation switch,' so your skin stops overreacting. That means less redness from acne, rosacea, eczema, or general sensitivity, and a more even, calm look.

    Copper Regeneration Peptide

    GHK-Cu

    What it is

    GHK-Cu is a skin repair signal. It helps firm up loose skin, smooth fine lines, fade scars, and speed up healing — basically turning back the clock on damage.

    How it functions

    It wakes up the cells that make your skin strong and stretchy, while delivering copper to help repair damage from aging, sun, and scarring. The result is firmer, smoother, healthier-looking skin over time.

    The Master Antioxidant

    L-Glutathione

    What it is

    Glutathione is like a shield for your skin. It helps fade dark spots, brighten a dull or tired complexion, and give skin a clearer, more even glow.

    How it functions

    Think of it as a cleanup crew for your skin. It helps clear away the buildup that makes skin look tired and patchy, while quietly fading the spots that make tone uneven.

    Brightens and evens skin tone
    Fades dark spots and post-acne marks
    Helps skin recover from daily stress
    Supports a clearer, healthier glow
