Sun Protection Factor (SPF) is a number that indicates the sunscreen's level of protection against UV (ultraviolet) B rays. The higher the number on the sunscreen packaging label, the greater the protection.

For daily use, what is the best SPF level for your skin?

Which is Better, SPF 30, SPF 50, or SPF 100?

The higher the SPF level, the more expensive the sunscreen will be. However, you should know that the increase in price of higher SPF sunscreens is not always proportional to the increase in protection provided.

For example, SPF 30 is often considered the breakpoint because it protects against about 97% of UVB rays, while higher SPFs only have a small incremental increase in protection.

When it comes to sunscreen, many factors affect the effectiveness of sunscreen, including proper application, skin type, time of sun exposure, and what activities are being performed. To determine which SPF level is better, you must consider these factors.

SPF 30 is generally considered the best option for most people with normal skin in daily use. The 97% UVB protection it provides can provide adequate protection when reapplied every 2 hours and after swimming or sweating.

SPF 50 provides slightly higher protection, around 98%. Sunscreens with SPF 50 levels tend to be better for sensitive skin types or when you have to spend longer in intense sunlight. You will still need to reapply sunscreen with SPF 50 regularly.

SPF 100 has a protection level of about 99%. Sunscreens with SPF this high may be an option for individuals with very sensitive skin, or prone to sunburn. Just like any other type of sunscreen, sunscreens with this SPF content should also be reapplied regularly.

So, the key to choosing a sunscreen is not the higher SPF number, but rather your needs, skin condition, and activities. A sunscreen with SPF 30 may be the most suitable for daily use if you have a normal skin type. You should consider higher SPF levels if you have sensitive skin or need to stay in the sun longer.
