Ingredient review
Myricitrin
INCI: MYRICITRIN
A plant-derived antioxidant that may help calm skin and defend against environmental stress, though human studies are limited.
In plain English
Myricitrin is a natural compound found in plants like bayberry and some berries. In skincare, it acts as an antioxidant, meaning it helps neutralize unstable molecules called free radicals that can damage skin cells. It also has soothing properties, which may help reduce redness or irritation. While lab studies show promise, there isn't much research yet on how well it works when applied to human skin in real products.

Quick decision guide
Useful, but context matters
Myricitrin 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 Myricitrin.
- 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
Myricitrin is a flavonoid glycoside, specifically a rhamnoside of myricetin. It is a yellow pigment found in the bark and leaves of plants such as Myrica cerifera (southern wax myrtle) and in some fruits. In cosmetics, it is used as an antioxidant and skin-conditioning agent.
How it works
Myricitrin works primarily by donating electrons to neutralize free radicals, preventing them from causing oxidative stress that can lead to premature aging and dullness. It also appears to inhibit certain enzymes involved in inflammation, which may help calm irritated skin. Additionally, some research suggests it can support collagen integrity by protecting against UV-induced damage.
Pros
Gentle antioxidant
Myricitrin is generally well-tolerated and unlikely to cause irritation, making it suitable for sensitive skin types.
Soothing potential
Early research indicates it may help calm inflammation, which could benefit those with redness or mild irritation.
Cons and cautions
Limited human evidence
Most studies on myricitrin are lab-based or animal studies; there is little clinical data confirming its benefits on human skin.
Less potent than alternatives
Compared to well-established antioxidants like vitamin C or ferulic acid, myricitrin may offer weaker protection against free radicals.
Best for
- Anyone looking for extra antioxidant protection in their routine
- Those with sensitive or easily irritated skin seeking a gentle soothing ingredient
Use caution if
- People with known allergies to plants in the Myrica family should patch-test first
Usage tips
Safety summary
Myricitrin appears safe for topical use with low irritation and allergy risk based on available data. However, comprehensive safety studies on long-term use are lacking.
Research notes
Research on myricitrin is mostly preclinical, showing antioxidant and anti-inflammatory activity in cell and animal models. Human clinical trials are needed to confirm its efficacy in skincare.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
