SPF is one of the most important steps in any skincare routine, yet also one of the most misunderstood.
Recent controversy surrounding sunscreen recalls and products failing to meet their labelled protection has raised understandable concern among consumers.
With so much confusion around what SPF ratings really mean, how much to apply, and which formulas offer the most dependable protection, it’s worth returning to the basics of what makes an SPF effective and trustworthy.
What SPF Actually Measures
SPF, or “Sun Protection Factor,” refers to protection against UVB rays: the type responsible for sunburn and contributing to long-term skin damage. SPF does not provide complete protection unless the product is also labelled as broad-spectrum, meaning it defends against UVA as well.
UVA rays penetrate deeper into the skin and are present all year round. They play a significant role in premature skin ageing and pigmentation concerns. A reliable sunscreen must provide protection against both UVA and UVB.
How Much SPF to Use (and Why It Matters)
Many SPF controversies stem not from the product itself, but from application. Sunscreen testing is done using a specific amount, and any less reduces the protection significantly.
For the face and neck, aim for roughly half a teaspoon. For the body, around a shot-glass equivalent is recommended. It’s also important to reapply every two hours during ongoing exposure, and after towel drying, sweating or swimming.
Daily application is essential even on cloudy days. UVA rays penetrate clouds, glass and windows, and accumulate over time.
Mineral vs Chemical: Is One Better?
There are two primary categories of sunscreen filters:
-
Mineral (physical)
These sit on the skin’s surface and reflect UV rays. They often feel more matte and can suit sensitive skin.
-
Chemical filters
These absorb UV rays and convert them into heat. They typically feel lighter and blend more seamlessly.
Neither option is inherently better; the right choice depends on your skin type, texture preference and how it fits into your routine. The best SPF is the one you will wear every single day.
