# Matta 2020 — Sunscreen Active Ingredients Absorption Study

## Quick Summary

Matta 2020 measured plasma concentrations of additional sunscreen active ingredients after sunscreen application.

## What Studied

Randomized clinical trial evaluating systemic absorption of several active ingredients found in sunscreen products.

## Main Findings

The study reported measurable plasma concentrations for multiple filters, including avobenzone, oxybenzone, octocrylene, homosalate, octisalate, and octinoxate.

## Why It Matters

It helps explain why regulators requested more data while keeping the page from overstating what absorption studies prove.
