Insufficient sun protection factor and UVA coverage limit the efficacy of topical barriers. Enhancing photoprotective capacity ensures reliable prevention of radiation-induced skin damage.

Low efficacy in blocking UV rays leads to inadequate skin protection and product failure. Enhancing the sun protection factor ensures safety and regulatory compliance.

Solidification or precipitation of active ingredients in liquid formulations reduces photoprotective efficacy. Preventing phase separation ensures long-term product homogeneity and skin coverage.
