What is Sunscreen?

Blocks UVA/UVB to prevent skin aging and pigmentation

Divided into physical (mineral) and chemical (organic) types; daily use is recommended.

Key properties & actions

Sunscreen is a product that helps protect the skin from UVA and UVB, which cause skin aging and pigmentation. Inorganic (physical) sunscreens reflect and scatter UV, while organic (chemical) sunscreens are understood to work by absorbing UV and releasing it as heat. SPF indicates the degree of UVB protection, and PA indicates the degree of UVA protection.

How to manage

Applying a generous recommended amount (about the size of a coin for the face) 15–30 minutes before going out, and reapplying every 2–3 hours during outdoor activity, is generally recommended. It is best to use it daily even on cloudy days and indoors. If eye-area irritation or breakouts persist, try changing the formula or consult a professional.

Good to know alongside

It is used at the very last step of basic skincare and is emphasized together with the use of ingredients that can increase photosensitivity, such as vitamin C and retinol. Formulas blending inorganic and organic filters are also commonly used.

Everyday care tips

When reapplication is inconvenient, carrying a sun stick or sun cushion to lightly top up over makeup can help maintain sun protection.
