Cosmetic efficacy testing provides scientific evidence that skin care, hair care, scalp care, sunscreen, and makeup products deliver their claimed benefits. Brands use cosmetic claim substantiation studies to support marketing claims, comply with cosmetic regulations, and demonstrate measurable product performance.

Whether for skin care, hair care, or personal care products, companies must demonstrate that their formulations deliver visible, measurable, and reliable results. Robust efficacy testing helps support product claims, build consumer trust, and meet regulatory expectations across global markets

CIRS offers comprehensive cosmetic efficacy testing services, including in vivo studies, in vitro testing, consumer perception research, and clinical evaluations to support claim substantiation and global regulatory compliance.
