Why SPF & UVA Testing Is Mandatory for Sunscreen and Cosmetic Products
Sun Protection Factor (SPF) testing scientifically evaluates a product’s ability to protect human skin from harmful ultraviolet radiation:
- UVB (290–320 nm)
Responsible for sunburn, erythema, and acute skin damage - UVA (320–400 nm)
Responsible for photoaging, pigmentation, and long-term skin damage
Modern cosmetic regulations require both SPF and UVA protection assessment to substantiate Broad Spectrum claims. Reliable SPF testing is essential for:
- Regulatory approvals under CDSCO and BIS (India)
- Compliance with EU Cosmetic Regulation (EC No. 1223/2009)
- SPF label claim substantiation (SPF 15 / 30 / 50 / 50+)
- Water resistance and UVA logo eligibility
- Consumer safety, transparency, and brand credibility
- Export documentation and international cosmetic dossiers
