Caffeoyl Hexapeptide-48

INCI: Caffeoyl Hexapeptide-48

A lab-made peptide that may help firm skin and soften wrinkles, but research is still early and results vary.

In plain English

Caffeoyl Hexapeptide-48 is a man-made ingredient that combines a small protein fragment (a peptide) with a molecule related to coffee (caffeoyl). In skincare, it's added to products like anti-aging serums and firming creams with the goal of encouraging the skin to look tighter and smoother. Think of it as a signal that tells skin cells to act more youthfully, though the evidence is still building and it's not a guaranteed fix.

Quick decision guide

Useful, but context matters

Caffeoyl Hexapeptide-48 is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Caffeoyl Hexapeptide-48.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A synthetic hexapeptide (a chain of six amino acids) that has been chemically linked to a caffeoyl group, which is derived from caffeic acid (found in coffee and plants). It is produced in a lab and used as an active ingredient in anti-aging cosmetics.

How it works

Peptides like this one are thought to work by mimicking natural signaling molecules in the skin. The caffeoyl group may help the peptide penetrate better or provide antioxidant support. Once absorbed, the peptide may signal skin cells to produce more collagen and elastin, which are proteins that keep skin firm and elastic. Over time, this could reduce the look of fine lines and improve skin texture.

Pros

Gentle on skin

Caffeoyl Hexapeptide-48 has a low irritation and comedogenic risk, making it suitable for sensitive or acne-prone skin types.

Targets aging signs

It is specifically formulated to support collagen production, which can help improve skin firmness and reduce the look of fine lines over time.

Cons and cautions

Limited evidence

There are few published human studies on this specific peptide, so its effectiveness is not as well-established as other anti-aging ingredients like retinol or vitamin C.

Subtle results

Improvements in skin texture and firmness are typically gradual and modest, which may not meet the expectations of those seeking dramatic changes.

Best for

  • Adults looking for a gentle anti-aging ingredient
  • Those with sensitive skin who cannot tolerate stronger actives like retinol

Use caution if

  • Anyone expecting fast or dramatic results
  • People on a very tight budget, as peptide products tend to be pricier

Usage tips

Apply a peptide serum to clean, damp skin before heavier creams to enhance absorption.
Use consistently for at least 8–12 weeks to see potential improvements in skin firmness.
Store peptide products away from direct sunlight and heat to maintain stability.

Safety summary

Caffeoyl Hexapeptide-48 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available research or regulatory reviews.

Research notes

Research on Caffeoyl Hexapeptide-48 is limited. Most evidence comes from in vitro (lab) studies and manufacturer data suggesting it can stimulate collagen synthesis. Human clinical trials are scarce, so the evidence level is considered emerging.

Common label clues

Typical concentration
Typically used at 0.1% to 1% in leave-on formulations
Regulatory status
Approved for use in cosmetics in the US, EU, and other major markets. It is not classified as a drug and cannot claim to treat or cure skin diseases.
Common uses
Anti-aging serums, Firming creams, Eye treatments
Environmental note
As a synthetic peptide, it is produced in controlled lab conditions, which reduces the need for plant harvesting. However, its environmental impact is not well-studied.

Good to know

  • Peptides are often listed near the end of ingredient lists because they are effective at low concentrations.
  • Caffeoyl Hexapeptide-48 is not the same as caffeine, though it shares a related chemical group.
