Ingredient review
Dicaffeoyl Lysyl Hexapeptide-65
INCI: Dicaffeoyl Lysyl Hexapeptide-65
A lab-made peptide with antioxidant-like modifications that may help firm skin, but human studies are still limited.
In plain English
This is a man-made peptide—a small chain of amino acids—that has been chemically linked to caffeic acid (a compound found in coffee and plants). In skincare, it's added to products aimed at firming the skin and softening wrinkles. Think of it as a signal molecule that tells skin cells to behave more youthfully, with an extra antioxidant boost from the caffeic acid parts.

Quick decision guide
Useful, but context matters
Dicaffeoyl Lysyl Hexapeptide-65 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 Dicaffeoyl Lysyl Hexapeptide-65.
- 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
Dicaffeoyl Lysyl Hexapeptide-65 is a synthetic peptide engineered by attaching two caffeic acid molecules to a specific hexapeptide sequence. It is not found in nature and is produced in a laboratory for cosmetic use.
How it works
The peptide portion is believed to mimic natural signaling fragments that encourage skin cells to produce more collagen and elastin, which help keep skin firm and plump. The attached caffeic acid groups may provide antioxidant activity, helping to neutralize free radicals that contribute to premature aging. Together, these actions aim to improve skin texture and reduce the look of fine lines over time.
Pros
Antioxidant-enhanced peptide
The caffeic acid groups add antioxidant properties, potentially offering extra protection against environmental damage compared to plain peptides.
Generally well-tolerated
Irritation and comedogenic risks are low, making it suitable for most skin types, including sensitive skin.
Cons and cautions
Limited human evidence
Most supporting data comes from lab or animal studies; robust human clinical trials are scarce, so real-world results may be modest.
Effectiveness depends on formulation
The peptide must be properly stabilized and delivered at an effective concentration; not all products containing it will perform equally.
Best for
- Adults looking to support skin firmness and reduce early signs of aging
- Those with normal to dry skin who want a gentle anti-aging ingredient
Use caution if
- Individuals with known allergies to synthetic peptides (rare)
- Anyone seeking immediate or dramatic wrinkle reduction
Usage tips
Safety summary
Dicaffeoyl Lysyl Hexapeptide-65 is considered safe for topical use in cosmetics at typical concentrations. Irritation and allergy risks are low, but as with any new ingredient, a patch test is recommended for first-time users.
Research notes
Evidence is primarily from in vitro (lab) studies showing collagen-stimulating and antioxidant effects. Human studies are limited, so the ingredient is best viewed as a promising but not yet proven anti-aging option.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- As a synthetic peptide, its production involves chemical synthesis, which has a moderate environmental footprint compared to natural extracts. Biodegradability data is not publicly available.
Good to know
- This ingredient is often listed near the middle or end of an ingredient list, indicating a lower concentration.
- It pairs well with other anti-aging ingredients like retinoids and vitamin C, but avoid using with very low pH formulas that could break down the peptide.
