[Beauty Tip] Does a high SPF cause skin problems?

Sunscreens are classified into physical sunscreens, which physically scatter light rays, and chemical sunscreens, which chemically absorb and neutralize them. Since chemical sunscreens can cause contact allergic dermatitis, their formulation limits are regulated by country; consequently, to increase the SPF, physical sunscreens are formulated to offer superior protection while containing fewer allergy-causing ingredients.

Therefore, it can be said that the composition is more important than the index.
