When choosing sunscreen, it is recommended to check the following indices as well.
- SPF: An index indicating the effectiveness of blocking UVB rays. Indicated as 2 to 50+.
SPF 50 or higher is indicated as '50+', and the higher the number, the greater the blocking effect.
- PA: An index indicating the effectiveness of blocking UVA rays. It is represented by +, ++, or +++. The more plus signs, the greater the blocking effect.
It is recommended to apply sunscreen with SPF 20–30/PA +~++ for daily life and SPF 30–50/PA ++~+++ for outdoor activities.
