Sunscreen guide for South African skin, all year round
Pretoria, Johannesburg, Bloemfontein and much of the country sit at high altitude with very high year-round UV. Cape Town and Durban add coastal reflection to the picture. Sunscreen in South Africa is not seasonal or optional. This guide walks through SPF, PA ratings, mineral versus chemical filters, and how to build daily sunscreen into a routine that actually gets used.
The South African UV context
South Africa's UV index regularly reaches 11 or higher in summer, which is classified as extreme. Even in winter, UV levels in the interior stay high enough to cause daily photoageing and hyperpigmentation.
Altitude increases UV exposure. Pretoria sits at 1339 metres, Johannesburg at 1753 metres. Every 1000 metres of elevation adds roughly 10 to 12 percent more UV.
SPF and PA explained
SPF measures protection against UVB, the wavelengths that cause burning.
PA ratings measure protection against UVA, the wavelengths that cause ageing and pigmentation. PA+++ or higher is a solid daily benchmark.
Broad-spectrum on the label means the product protects against both. This is the minimum for daily use.
Mineral vs chemical
Mineral sunscreens use zinc oxide and titanium dioxide to reflect and absorb UV. They sit on the surface, start working immediately, and are the safer choice for very sensitive skin. Modern formulas have largely solved the white cast issue.
Chemical sunscreens use organic filters that absorb UV. They feel lighter, blend invisibly, and require 15 to 20 minutes to activate.
Hybrid formulas combine both and are the sweet spot for many people.
How much to apply
Two milligrams per square centimetre of skin is the tested application amount. In practice, that is about a two-finger length of product for the face and neck. Most people apply half that, which delivers roughly half the labelled SPF.
Reapplication reality
Every two hours in direct sun. Every hour after swimming or sweating.
For daily desk work, one solid morning application is usually enough if you are not near a window all day.
Powder or spray reapplication over makeup is better than nothing, but it does not deliver the full labelled SPF.
Where sunscreen fits in your routine
SPF is the last step of the morning routine, applied after moisturiser and before makeup. Mixing SPF into moisturiser dilutes it below the tested value.
Common myths
Higher SPF is not always dramatically better. SPF 30 blocks about 97 percent of UVB, SPF 50 blocks about 98 percent. The bigger factor is application amount and reapplication.
Darker skin also needs sunscreen. Melanin offers some protection but does not prevent UV damage, hyperpigmentation or skin cancer.
Cloudy days still deliver UV. Up to 80 percent of UV passes through cloud cover.

Questions, answered.
What SPF do I need in South Africa?
Broad-spectrum SPF 30 minimum for daily use, SPF 50 for prolonged outdoor time. PA+++ or higher for UVA protection.
Do I need sunscreen in winter?
Yes. South Africa's winter UV is still high, especially at altitude and in the interior. Daily sunscreen is a year-round habit.
Is mineral or chemical sunscreen better?
Both are effective. Mineral is preferable for very sensitive skin. Chemical formulas feel lighter under makeup. Hybrids are a good middle ground.
