UnverifiedSPF值越高防护越强但肤感越厚重、致敏概率越高；SPF30已能阻挡约97%的UVB，SPF50约98%，从30到50提升有限，日常没必要盲目追高90% similarUnverifiedSPF50与SPF30的实际防护差异仅约1.3%（分别阻挡98%和96.7%的UVB），SPF50并非好一倍，防护关键在于足量涂抹和补涂86% similarUnverifiedSPF值超过50对UVB防护提升边际效应极小（SPF50阻挡约98%，SPF100约99%），不必为高数值支付溢价，反而高浓度化学防晒剂刺激性更强85% similarUnverified日常遮阳选SPF30~50即可，SPF50以上防护提升有限（SPF30阻挡约97%UVB，SPF50约98%），但配方更厚重、白残留更明显，反而降低涂抹意愿83% similarUnverifiedSPF数值与防护率非线性: SPF15阻挡约93%UVB，SPF30约97%，SPF50约98%，从30升到50提升仅约1%，日常通勤SPF30已足够，追求更高数值意义有限反而增加油腻感83% similar
