Sun Protection Factor or SPF measures the ability of the sunscreen to protect the skin from UVB rays. These rays cause sunburn and can cause skin cancer. An SPF of 30 means that it will take 30 times longer for the skin to burn than if there was no sunscreen protection in place.
Specifically, SPF 30 blocks around 97% of UVB rays, while SPF50 blocks 98% and SPF 15 blocks 93%. The numbers are references not the duration of protection, but the level of UVB filtering. These differences may be small, but the difference is massive, especially for those with sensitive skin.

Importantly, sunscreen needs to be reapplied throughout the day (typically every two hours especially if you’ve been sweating, swimming or drying yourself) and does not offer 100% protection. Really though, you should look at broad-spectrum sunscreens as these also protect from UVA as well. UVA rays can penetrate through windows and also contribute to ageing and hyperpigmentation, which is why it’s important to consider indoor use as well.
Choosing a sunscreen carefully is important. Make sure you select one that is water-resistant, and matches your skin type so that you consider oily vs dry. You should also think about the benefits of mineral versus chemical filters, though this depends on each individual and their needs.
Choosing the right sunscreen is essential if you want to protect your skin. When you choose a sunscreen, consider your age, skin tone and skin condition before picking which one you want to use. This means considering whether you have acne, sensitivity to some ingredients or have melasma. You should also consider the sun exposure frequency to determine the strength you need.
For instance, children have delicate skin and are more sensitive to UV damage than adults are. From an early age, sunscreen is essential, but not all can be used on children, especially babies. Under 6 months, no sunscreen should be used as their skin is too sensitive. Instead, avoid going out in the sun and use clothing for protection. Children over 6 months should be using SPF 30 or higher and should use a mineral filter like zinc oxide. This is less likely to irritate the skin. Use cream or sticks for optimal coverage rather than a spray.
For adults looking for daily use, then SPF 30 is enough. If prolonged sun exposure is expected, or you have sensitive skin, then use SPF 50. Depending on your lifestyle, consider changing things up.
Commuting, running short errands, or being indoors, then SPF 15-30 is fine. Being outdoors or at the beach means considering SPF 50 PA+++ or ensuring its water resistant. Contrary to popular belief, all skin tones need sunscreen as melanin, while offering some protection, does not shield against UVA. Darker tones should use broad-spectrum formulas to prevent pigmentation.
With all this in mind, it’s essential to invest in high-quality sunscreen. This aids in effectiveness, but also for long-term skin health. Sunscreen is always expensive, and premium brands come at an even higher cost.

Daily sunscreen is a must, even during cloudy weather and living indoors. There are some application practices you should consider too, such as applying 15 minutes before going outsides, covering all exposed skin making sure to do overlooked areas such as the ears and back of the neck.
You should always be generous in your usage, and make sure to check the expiration date (usually 3 years). Many users under-apply, which reduces protection and efficacy. Sunscreen is not just a beach item, but is a major part of a solid skincare regimen, preventing ageing, pigmentation and other health risks. Explore the sunscreen options out there, talk to a dermatologist, and use sunscreen on a daily basis.
