Ingredient review
Melittin
INCI: MELITTIN
Melittin is a bee venom peptide with promising lab research, but it's a strong irritant and not well-studied in cosmetic use—caution is advised.
In plain English
Melittin is a protein found in bee venom. In a lab, it can calm inflammation and fight certain bacteria, but it's also what makes a bee sting hurt and swell. In skincare, it's used in tiny amounts, but even then it can irritate sensitive skin. Think of it as a very strong ingredient that needs careful handling.

Quick decision guide
Read the cautions before using
Melittin can be useful, but watch for high irritation potential.
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 Melittin.
- 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
highMore likely to cause dryness, stinging, peeling, or reactivity if used too aggressively.
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
Melittin is the main active component of bee venom, making up about 50% of the venom's dry weight. It is a small peptide (a chain of amino acids) that can interact with cell membranes.
How it works
In a cosmetic product, melittin is thought to stimulate blood flow and immune response in the skin, which may temporarily plump or firm the skin. It also has antimicrobial properties that could help with acne-causing bacteria. However, these effects are based on limited research, and the irritation risk is significant.
Pros
Promising lab research
Studies show melittin can reduce inflammation and fight certain bacteria, which could benefit acne or aging skin if proven in humans.
Novel ingredient appeal
For skincare enthusiasts seeking cutting-edge ingredients, melittin offers a unique mechanism that differs from common peptides.
Cons and cautions
High irritation risk
Melittin is a known irritant that can cause redness, swelling, and stinging, especially for sensitive or reactive skin types.
Limited cosmetic evidence
Most research is lab-based or on wounds, not on cosmetic use for healthy skin. Long-term safety and efficacy are not established.
Best for
- People with resilient, non-sensitive skin looking for experimental ingredients
- Those who have used bee venom products before without reaction
Use caution if
- Anyone with bee sting allergies or sensitive skin
- Pregnant or breastfeeding individuals due to lack of safety data
Usage tips
Safety summary
Melittin has potential benefits but carries a high risk of irritation and allergic reactions. It is not suitable for sensitive skin or those with bee allergies. More research is needed to confirm its safety and effectiveness in everyday skincare.
Research notes
Research on melittin is mostly preclinical, showing anti-inflammatory and antimicrobial effects in cell and animal studies. Human studies on cosmetic use are scarce, so the evidence level is considered emerging.
Common label clues
- Typical concentration
- Very low (typically under 0.001%)
- Regulatory status
- Melittin is not specifically regulated by the FDA for cosmetics, but bee venom is generally considered safe in low concentrations. However, it is not recommended for use on broken or irritated skin.
- Common uses
- Serums, Anti-aging creams
- Environmental note
- Harvesting bee venom can stress bee colonies if not done sustainably. Look for brands that source from ethical, bee-friendly suppliers.
Good to know
- Melittin is often listed as 'Bee Venom' on product labels, but the concentration is usually very low.
- Products with melittin may cause a temporary tingling or warming sensation, which is normal but should not be painful.
