In plain English

This ingredient is a man-made chemical that absorbs ultraviolet (UV) light from the sun, preventing it from reaching and damaging your skin. It's used in sunscreens and some makeup products to provide sun protection. Think of it as a tiny sponge that soaks up UV rays before they can cause sunburn or long-term skin aging.

Quick decision guide

Useful, but context matters

Methoxyphenylamino Phenylpyrazole 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Methoxyphenylamino Phenylpyrazole.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic organic compound belonging to the phenylpyrazole family, designed to absorb UV radiation, particularly in the UVA range.

How it works

It works by absorbing UV light energy and converting it into harmless heat, which is then released from the skin. This prevents the UV rays from penetrating deeper and causing cellular damage.

Pros

Effective UVA protection

Helps shield skin from UVA rays, which are linked to premature aging and skin damage.

Good photostability

Remains effective longer under sunlight compared to some other chemical filters, reducing the need for frequent reapplication.

Cons and cautions

Limited market presence

Not approved in all countries, so you may have difficulty finding products containing it outside certain regions.

Less research available

Compared to common filters like avobenzone or zinc oxide, there is less published safety and efficacy data for this specific compound.

Best for

  • People looking for broad-spectrum sun protection
  • Those with sensitive skin who tolerate synthetic filters well

Use caution if

  • Individuals with known allergies to phenylpyrazole compounds
  • Those seeking purely mineral (physical) sunscreens

Usage tips

Apply sunscreen generously 15 minutes before sun exposure
Reapply every two hours or after swimming/sweating
Use as part of a complete sun protection routine including shade and protective clothing

Safety summary

Generally considered safe for topical use at approved concentrations. Rare reports of skin irritation or allergy exist, but it is well-tolerated by most users.

Research notes

Moderate evidence supports its efficacy as a UV filter. More long-term human and environmental studies are needed to fully assess its safety profile.

Common label clues

Typical concentration
Up to 3% in leave-on products
Regulatory status
Approved for use in sunscreens in some regions (e.g., Japan, Korea) but not currently approved by the FDA in the United States. Always check local regulations.
Common uses
Sunscreens, Tinted moisturizers, BB creams
Environmental note
Synthetic UV filters have been detected in aquatic environments; however, the environmental impact of this specific compound is not well-studied.

Good to know

  • This ingredient is often combined with other UV filters for broader protection
  • It is not a physical blocker like zinc oxide, so it won't leave a white cast
