Ingredient review
Myrcene
INCI: MYRCENE
Myrcene is a plant-derived terpene with antioxidant potential, but its primary role in skincare is often as a fragrance component, and it may cause irritation in sensitive individuals.
In plain English
Myrcene is a natural compound found in plants like hops, lemongrass, and cannabis. In skincare, it's mainly used to add a pleasant scent and to help protect the skin from damage caused by free radicals (unstable molecules that can harm skin cells). However, because it's a strong-smelling essential oil component, it can sometimes irritate sensitive skin or cause allergic reactions.
Quick decision guide
Useful, but context matters
Myrcene can be useful, but watch for some 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 Myrcene.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
Myrcene is a monoterpene, a type of volatile organic compound produced by many plants. It is a key component of essential oils from hops, lemongrass, bay leaves, and cannabis, and is often extracted for use in cosmetics and fragrances.
How it works
In skincare products, myrcene acts primarily as a fragrance ingredient, providing a pleasant, earthy, or citrusy scent. It also has antioxidant properties, meaning it can help neutralize free radicals that contribute to skin aging and damage. However, its volatility means it can evaporate quickly, and its potential for skin sensitization limits its concentration in leave-on products.
Pros
Natural antioxidant
Myrcene can help neutralize free radicals, potentially reducing oxidative stress on the skin from pollution and UV exposure.
Pleasant natural scent
It provides an earthy, slightly citrusy aroma that can make skincare products more enjoyable to use without synthetic fragrances.
Cons and cautions
Potential skin irritant
As a terpene, myrcene can cause redness, itching, or stinging, especially for those with sensitive skin or fragrance allergies.
Limited functional benefit
In most skincare products, myrcene is used at very low levels primarily for scent, so its antioxidant effects are minimal compared to dedicated antioxidants like vitamin C or E.
Best for
- Those with normal to oily skin looking for a natural-scented antioxidant product
- Individuals who tolerate essential oils well and want a plant-based fragrance option
Use caution if
- People with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to terpenes or essential oils
Usage tips
Safety summary
Myrcene is considered safe for most people when used in low concentrations in cosmetics. However, it is a known skin sensitizer and can cause allergic reactions or irritation, particularly in those with sensitive skin or fragrance allergies. Regulatory bodies like IFRA recommend usage restrictions to minimize risk.
Research notes
Research on myrcene's topical effects is limited. Most studies focus on its antioxidant and anti-inflammatory properties in vitro or in animal models. Human studies on its efficacy in skincare are sparse, and its primary function in commercial products remains as a fragrance component.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to its strong scent and potential for irritation.
- Regulatory status
- Myrcene is generally recognized as safe (GRAS) by the U.S. FDA for use as a food additive. In cosmetics, it is regulated as a fragrance ingredient and must be listed on the label. The International Fragrance Association (IFRA) sets usage limits to minimize skin sensitization.
- Common uses
- Facial serums, Moisturizers, Body lotions
- Environmental note
- Myrcene is naturally derived from renewable plant sources, but its extraction and distillation processes can have environmental impacts. Sustainable sourcing practices are important.
Good to know
- Myrcene is often found alongside other terpenes like limonene and linalool in essential oil blends.
- It is also used as a flavoring agent in foods and beverages.
