The sun protection factor (SPF) refers to the ability of sunscreen products to protect against UV damage. There is a common misconception that higher SPF sunscreen products are always better. However, the reality is that different occasions require different levels of SPF protection. So, what SPF is appropriate?
What SPF is appropriate?
The SPF indicates the effectiveness of a sunscreen product in defending against UV rays. The appropriate SPF for sunscreen products depends on factors such as individual skin type, occasion of use, sweating conditions, etc. Generally, the SPF range for sunscreen products is between 15 and 80.
SPF 30 is suitable for East Asians
East Asians typically have yellow-toned skin, and an SPF around 30 is suitable for them. If the skin is yellowish and fair, using SPF 30 sunscreen products on a daily basis can help reduce skin spots and tanning. If the skin is yellowish and dark, choosing an SPF below 30 can still provide daily protection.
SPF 50+ is suitable for prolonged outdoor exposure
If you need to stay outdoors for a long time, it is best to choose sunscreen products with an SPF of 50 or higher. This can effectively protect against intense UV rays, especially for those who need to be outdoors between 10 am and 3 pm. A low SPF may not provide effective sun protection during this time period.
SPF 15 is suitable for prolonged indoor exposure
If you are an office worker and only encounter UV rays during your commute, using SPF 15 sunscreen products can help protect against sun damage and also provide a barrier against pollutants and dust. It is important for this group to focus on facial sun protection.
SPF 30 is suitable for heavy sweating
If you sweat heavily, it is best to choose waterproof sunscreen products. Excessive sweating can easily wash away sunscreen, rendering it ineffective. Waterproof and sweat-resistant sunscreen products can maintain their sun protection capabilities. Generally, an SPF of around 30 is sufficient.
