About this sunscreen
St. Barth Roucou Tanning Oil SPF 50 is a chemical sunscreen oil using modern filters: Tinosorb S, Uvinul A Plus, and Uvinul T 150. The oil format gives a dewy, glossy finish with low white cast and stays lightweight, and it is generally gentle with low sting risk. Breakout risk is low, so it tends to work for skin that tolerates oils well. Scoring 86.4 with good protection, it is a strong choice for a glowy, sun-protective body or face oil.
