Ingredient review
RH-Polypeptide-62
INCI: RH-Polypeptide-62
RH-Polypeptide-62 is a lab-made peptide that may help support collagen and improve skin firmness, but research is still early.
In plain English
RH-Polypeptide-62 is a synthetic peptide, which is a short chain of amino acids (the building blocks of proteins). In skincare, it's used to signal skin cells to behave more youthfully, potentially boosting collagen production and improving firmness. Because it's made in a lab, it's consistent and stable, but it's a newer ingredient so long-term studies are limited.

Quick decision guide
Useful, but context matters
RH-Polypeptide-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.
- Step 1Start with the score, then check the irritation and clogging risk before judging RH-Polypeptide-62.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide engineered to mimic a fragment of human collagen or signaling proteins, intended to communicate with skin cells to support repair and renewal processes.
How it works
When applied topically, RH-Polypeptide-62 is thought to bind to receptors on skin cells, triggering signals that encourage collagen synthesis and reduce the breakdown of existing collagen. This can lead to firmer, smoother skin over time.
Pros
Low irritation potential
RH-Polypeptide-62 is generally gentle on the skin, making it suitable for sensitive skin types when formulated properly.
Targeted anti-aging action
It works by signaling skin cells to produce more collagen, which can help improve firmness and reduce fine lines over consistent use.
Cons and cautions
Limited research
As a newer peptide, there are fewer peer-reviewed studies and long-term safety data compared to well-established peptides.
Variable efficacy
Results depend heavily on the formulation, concentration, and delivery system; not all products will deliver noticeable benefits.
Best for
- People looking for anti-aging support with minimal irritation
- Those who want to incorporate peptides into their routine
Use caution if
- Anyone with known allergies to synthetic peptides (rare)
- Those expecting instant results—peptides take time
Usage tips
Safety summary
RH-Polypeptide-62 is considered safe for topical cosmetic use at typical concentrations. Irritation and allergy are rare, but patch testing is recommended for new users.
Research notes
Evidence is primarily based on in vitro studies and limited clinical trials. More robust human studies are needed to confirm efficacy and long-term benefits.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- Approved for cosmetic use in most regions including the EU and US, as long as it meets purity and safety standards.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic ingredient, it does not rely on plant harvesting, but its production involves chemical synthesis which has an environmental footprint.
Good to know
- Peptides are fragile and can be destabilized by very low or high pH; look for products with a balanced pH.
- RH-Polypeptide-62 is often combined with other peptides or antioxidants for enhanced effects.
