Speaking of sun protection: what is SPF?
Understand what this acronym means and what to consider when choosing the best one for you.
When buying sunscreen, have you ever stopped to wonder what SPF means and how truly important it is? Well, SPF stands for Sun Protection Factor.
This factor indicates the level of protection that the product offers against UVB rays — the main cause of sunburn, premature ageing, and even skin cancer. In other words: the higher the SPF, the greater the protection!
How to choose the ideal SPF for you
The choice of SPF will depend on a few factors, such as your skin type, sun exposure, and, of course, your daily activities.
For the face
It’s recommended to use sunscreen with a high SPF, above 30. If your skin is sensitive or you’re the type who’s often exposed to the sun, it’s best to opt for a product with a higher SPF.
At Ollie, you’ll find sunscreens with very high protection levels — SPF 50+ — such as the Tinted Stick, 3-in-1. Suitable for all skin types, the sticks also offer everyday practicality and, depending on the product, some makeup coverage.
For the body
Generally, SPF 30 is enough for most daily activities, but people with fairer skin or those who spend long periods outdoors may prefer SPF 50+, for example.
What’s the difference between the factors?
The main difference between SPF ratings is the level of protection against UVB rays:
-
SPF 30: blocks approximately 97% of UVB rays
-
SPF 50: blocks around 98% of UVB rays
-
SPF 50+: offers even greater protection, blocking about 99%
Although these numbers may seem close, that difference can make a real impact on daily protection, especially for those with sensitive skin or specific conditions.
Does SPF 30 sunscreen protect?
Yes! An SPF 30 sunscreen provides good protection for most people on a daily basis — as long as it’s applied properly and reapplied every two hours, or after water exposure or sweating.
Why use the recommended SPF?
Using the right SPF is essential to prevent sunburn, premature ageing, and more serious skin problems. Sun protection also helps keep your skin healthy, beautiful, and shielded from the sun’s harmful effects.
The importance of reapplication
Even when using high-SPF sunscreen, its effectiveness decreases over time. That’s why the Brazilian Society of Dermatology (SBD) recommends reapplying the product every two hours — especially during intense heat, sweating, or after contact with water.
In summary
Want to keep your skin well protected?
Choose a sunscreen with a high SPF, stick to trusted brands (and don’t forget to consult your dermatologist), and always remember to reapply whenever necessary!
