Tamilnadu test House provides comprehensive in vivo & in vitro Sunscreen testing services including SPF testing, water resistance, and UVA protection studies, which are tailored to meet your unique regulatory requirements and support your marketing claims.
SPF is a measure of how much solar energy (UV radiation) is required to produce sunburn on protected skin (i.e., in the presence of sunscreen) relative to the amount of solar energy required to produce sunburn on unprotected skin. As the SPF value increases, sunburn protection increases.
