Ingredient review
Diglycosyl Hexapeptide-2
INCI: Diglycosyl Hexapeptide-2
A sugar-modified peptide that may help firm skin and soften fine lines with low irritation potential.
In plain English
Diglycosyl Hexapeptide-2 is a lab-made peptide (a small protein fragment) that has been attached to sugar molecules. This sugar modification helps the ingredient stick to the skin better and may improve its anti-aging effects. In skincare, it is used to support the skin's natural structure, potentially making it feel firmer and look smoother over time. It is generally well-tolerated and unlikely to clog pores or cause irritation.

Quick decision guide
Useful, but context matters
Diglycosyl Hexapeptide-2 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 Diglycosyl Hexapeptide-2.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic hexapeptide (a chain of six amino acids) that has been chemically linked to sugar groups (diglycosyl). This modification is designed to enhance the peptide's stability and its ability to bind to skin cells, potentially boosting its anti-aging activity.
How it works
The peptide portion is thought to signal skin cells to produce more collagen and other structural proteins, which can help improve skin firmness and elasticity. The sugar groups may help the peptide adhere to the skin's surface longer, allowing for better delivery and sustained activity. Over time, this can lead to a reduction in the appearance of fine lines and wrinkles.
Pros
Gentle on skin
Has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Supports skin structure
May stimulate collagen production, helping to improve skin firmness and elasticity over time.
Cons and cautions
Slow results
Visible improvements in firmness and wrinkles typically require consistent use for several weeks to months.
Limited research
There is less independent clinical data for this specific peptide compared to more widely studied anti-aging peptides.
Best for
- Anyone looking to improve skin firmness and reduce early signs of aging
- People with sensitive skin who want a gentle anti-aging option
Use caution if
- Those seeking immediate or dramatic wrinkle reduction (results are subtle and gradual)
- Individuals with known allergies to synthetic peptides (rare)
Usage tips
Safety summary
Diglycosyl Hexapeptide-2 has a strong safety profile with low irritation and comedogenic potential. It is well-tolerated by most skin types, including sensitive skin. No significant safety concerns have been reported in cosmetic use.
Research notes
Peptides in general have moderate evidence supporting their anti-aging benefits, particularly for collagen stimulation. While specific studies on Diglycosyl Hexapeptide-2 are limited, its mechanism is consistent with other well-studied peptides. More independent research would strengthen the evidence base.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on formulations
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used at typical concentrations. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced in a lab, which reduces the need for natural resource extraction. Its environmental impact is considered low at typical usage levels.
Good to know
- The sugar modification (diglycosyl) is intended to improve the peptide's stability and skin adhesion.
- This ingredient is often found in anti-aging serums and eye creams targeting firmness and fine lines.
