Sunscreen Essentials: Choosing and Using the Right SPF and PA Products
Understanding and correctly using sunscreen is essential for effective skin protection. This guide will help you choose the right SPF and PA-rated Plustem products and explain how to use them for maximum benefit.
Understanding SPF:
SPF (Sun Protection Factor) indicates how long sunscreen will protect you from UVB rays, the primary cause of sunburn. A higher SPF number offers more protection.
SPF Table for Reference:
- SPF 15: Blocks ~93% of UVB rays - Short daily exposure, minimal outdoor activities
- SPF 30: Blocks ~97% of UVB rays - Fair skin, outdoor activities, moderate exposure
- SPF 50: Blocks ~98% of UVB rays - Very fair skin, intense sun exposure, high-altitude activities
PA Ratings: Understanding UVA Protection:
The PA rating system, originating in Japan, measures UVA protection. UVA rays, unlike UVB, penetrate deep into the skin, causing aging and long-term damage.
PA Ratings Explained:
- PA+: Some UVA protection - Ideal for indoor exposure or brief outdoor activities
- PA++: Moderate UVA protection - Suitable for regular daily activities
- PA+++: High UVA protection - Recommended for prolonged outdoor exposure
Applying Sunscreen Effectively:
Quantity Matters: Apply about half a teaspoon of sunscreen to your face. For the body, use an amount roughly the size of a shot glass. Read more on effective sunscreen application in winter.
Timing is Key: Apply sunscreen 30 minutes before going outdoors. Reapplication: Reapply every two hours, or more frequently if swimming or sweating.
How SPF Protects Your Skin:
SPF works by absorbing, reflecting, or scattering sunlight. It prevents UVB rays from burning the skin and minimizes damage caused by UV radiation.
Do You Need Sunscreen Indoors?
While UVB rays are mostly blocked by windows, UVA rays can still penetrate glass, posing a risk of aging and long-term skin damage. Furthermore, indoor environments often expose us to blue light from digital devices and NIR, both of which can affect skin health. Wearing sunscreen indoors, especially one that offers blue light and NIR protection like Plustem products, can be beneficial in safeguarding your skin against these diverse light sources.
