The numbers do not lie
Research shows that up to 80 to 90% of visible signs of skin aging. Wrinkles, pigmentation, loss of firmness are caused by UV radiation. Not by age itself, but by the cumulative exposure to the sun over the years. Scientists call this 'photoaging'.
That also means: the best anti-aging investment you can make has nothing to do with the most expensive serum or the latest technology. It is consistently using sun protection every day, all year round.
UVA vs UVB. The difference that matters
UV radiation consists of two types of wavelengths, each with a different effect on the skin. UVB rays are the 'burning' rays responsible for sunburn. They play a role in skin cancer but do not penetrate glass and are stronger in summer. UVA rays are the 'aging' rays. They penetrate deeper into the skin, damage collagen and elastin, and are equally strong all year round. They also penetrate windows and clouds.
That is why SPF is important even on cloudy days and indoors. The SPF number on a product primarily protects against UVB. For UVA protection, look for 'broad spectrum' on the packaging, which is exactly what our SPF 50 Sunscreen Stick provides.
Mineral vs chemical. What is the difference?
There are two types of sun protection: chemical filters and mineral filters. Chemical filters absorb UV radiation and convert it into heat. Mineral filters, such as zinc oxide and titanium dioxide, reflect UV radiation like a mirror. Mineral filters are gentler on the skin, less taxing on the environment and suitable for sensitive skin.
The SESE SPF 50 Sunscreen Stick works exclusively with mineral filters. Reef-friendly. No white cast thanks to the fine formulation. Safe for children from age 3.
Why a stick and not a cream?
The stick format is compact, easy to carry and convenient for reapplication throughout the day, even over makeup. No mess, quick and targeted application. Ideal for the eye area, nose and lips. Zones that are particularly vulnerable but often forgotten during regular SPF application.
✦ Apply SPF as the last step of your morning routine, after your day cream.
✦ Reapply every two hours during prolonged sun exposure.
✦ Use it in winter too: UVA radiation is active all year round.
The simplest anti-aging habit you can start today
You do not need to follow a complicated regime. If you add one thing to your routine today, let it be SPF. It is the most evidence-based, most effective protection that exists. And at SESE, we made it as easy as possible to take that step every single day.
