How to choose sunscreen

PA and SPF ratings indicated on sunscreen?

The PA and SPF indices indicated on sunscreen are units that represent the effectiveness of UV protection. PA indicates the degree of protection against UVA rays, which cause skin aging. The more plus signs there are, the higher the effectiveness in blocking UVA rays.

For autumn or winter, or for indoor use, PA 10/PA+ is sufficient, but for summer or prolonged outdoor activities, it is recommended to choose a product with PA+++ / PA 10 or higher.

 


Inorganic vs. Organic Sunscreen for My Skin?

Mineral sunscreens block UV rays by reflecting sunlight, so they are less irritating to the skin. However, they can leave a white cast and have a stiff texture, so those with dry skin may worry about their skin looking cakey.

On the other hand, organic sunscreens absorb and disperse UV rays, allowing them to penetrate the skin smoothly without leaving a white cast; however, they can be irritating to sensitive skin, so it is important to choose the right product according to your skin condition.

 

Sunscreen Tip!


1. Apply an amount the size of a 500-won coin 30 minutes before going out.
Sunscreen should be applied 30 minutes before going out. This is because it needs to be fully absorbed into the skin in advance to maximize its protective effect.

 
2. Apply frequently rather than a large amount at once.
Since the sunscreen's protective power can decrease during prolonged outings, it is important to reapply it every two hours.

 
3. If you have oily skin? Sun stick recommendations
Since sunscreen itself is oily, the base makeup often smudges when applied over it. In such cases, try using a sun stick to ensure better adhesion.
 

4. When reapplying over makeup, use sun spray or sun cushion!
If you apply cream or stick types over makeup, there is a risk that the makeup will rub off. Use a sun cushion or sun spray with UV protection.
