Tetrapeptide-62

INCI: Tetrapeptide-62

Tetrapeptide-62 is a lab-made peptide that may help support collagen production and improve skin firmness, but research is still early.

In plain English

Tetrapeptide-62 is a short chain of four amino acids (the building blocks of protein) created in a lab. In skincare, it's added to products like serums and creams with the goal of encouraging your skin to produce more collagen and elastin, which can help reduce the appearance of fine lines and sagging. Think of it as a tiny signal that tells your skin cells to get to work repairing and firming up. Because it's a synthetic peptide, it's designed to be stable and effective in formulas, but it's still a newer ingredient with limited independent studies.

Quick decision guide

Useful, but context matters

Tetrapeptide-62 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 Tetrapeptide-62.
  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

Tetrapeptide-62 is a synthetic peptide composed of four specific amino acids. It belongs to a class of signaling peptides that are engineered to mimic natural peptide fragments in the skin, potentially triggering collagen synthesis and other repair processes.

How it works

When applied topically, Tetrapeptide-62 is thought to penetrate the outer layer of skin and bind to receptors on fibroblasts (the cells that produce collagen). This binding may send a signal to ramp up production of collagen and other structural proteins, helping to strengthen the skin's support network and reduce visible signs of aging.

Pros

Low irritation risk

Tetrapeptide-62 is generally very gentle on the skin, making it suitable for sensitive skin types that may react to stronger anti-aging actives like retinol or acids.

Targeted collagen support

As a signaling peptide, it directly encourages your skin's own collagen production, which can lead to firmer, more resilient skin over time without harsh side effects.

Cons and cautions

Limited research

Compared to well-studied peptides like Matrixyl, Tetrapeptide-62 has fewer independent clinical trials, so the evidence for its effectiveness is still emerging.

Subtle results

Peptides generally work slowly and subtly. You may not see dramatic changes, and consistent daily use over several months is typically needed for any visible improvement.

Best for

  • Adults looking for a gentle anti-aging ingredient to support collagen
  • Those with sensitive skin who want a low-irritation peptide option

Use caution if

  • Anyone with a known allergy or sensitivity to synthetic peptides (rare)

Usage tips

Apply Tetrapeptide-62 products after cleansing and before heavier creams to allow better absorption.
Use consistently twice daily for at least 8–12 weeks to evaluate results.
Pair with a broad-spectrum sunscreen during the day to protect the collagen you're trying to build.

Safety summary

Tetrapeptide-62 is considered safe for cosmetic use at typical concentrations. It has a low irritation and comedogenic profile, making it suitable for most skin types. As with any new ingredient, a patch test is recommended for those with very sensitive skin or allergies.

Research notes

Research on Tetrapeptide-62 is still in early stages. While the mechanism of signaling peptides is well understood, specific clinical data for this exact peptide is limited. Most evidence comes from manufacturer studies rather than independent peer-reviewed journals.

Common label clues

Typical concentration
Typically used at 0.1% to 1% in leave-on products
Regulatory status
Tetrapeptide-62 is a cosmetic ingredient regulated as a cosmetic raw material. It is not classified as a drug and is not intended to treat or prevent disease. Always follow product usage directions.
Common uses
Anti-aging serums, Firming creams, Eye treatments
Environmental note
As a synthetic peptide, Tetrapeptide-62 is produced in controlled laboratory conditions, which reduces the environmental impact associated with harvesting natural ingredients. However, its biodegradability and long-term ecological effects are not well documented.

Good to know

  • Tetrapeptide-62 is often combined with other peptides or antioxidants in formulas for a synergistic anti-aging effect.
  • It is water-soluble and typically found in the water phase of a formulation, so it layers well under moisturizers.
