Questions & Answers

Everything you need to know

PEPTiPEN is a precision peptide delivery system that uses a micro-channel applicator to deposit bioactive peptides directly into the dermis. Unlike conventional creams that sit on the skin surface, PEPTiPEN bypasses the epidermal barrier for deeper, faster results - without needles or downtime.
All four PEPTiPEN formulas (RETA, NAD+, GLOW, KLOW) are dermatologist-tested and validated for sensitive, dry, oily, and combination skin. Our Peptide Fit Score™ helps you identify the formula with the highest compatibility for your specific skin profile. If you have known allergies, consult our expert board before starting.
The Peptide Fit Score™ is a proprietary 0-100 rating that evaluates any skincare formula across three scientifically-grounded dimensions: ingredient safety, bioactive peptide efficacy, and individual skin-type suitability. Scores are calculated by our algorithm and validated by our 7-member Medical Board of qualified scientific reviewers and cosmetic chemists.
  • RETA - Retatrutide research compound. Studied for metabolic receptor activity in preclinical models.
  • NAD+ - Cellular energy & NAD+ boosting peptides. Best for fatigue, dullness and barrier repair.
  • GLOW - Radiance & brightening peptides. Best for uneven tone, pigmentation and luminosity.
  • KLOW - Calming & anti-sensitivity peptides. Best for redness, reactivity and sensitive skin.
PEPTiPEN is an independent skincare brand. Our Medical Board members serve in an advisory capacity and represent their own professional expertise. Their endorsement does not imply affiliation with any hospital, clinic, or academic institution unless explicitly stated in their individual biographies.
