SPF50: Simple sun protection

SPF50: simple sun protection

The sun is appealing, it feels good, and it lifts your mood. But it's also the biggest factor in aging the skin and, in the short term, the reason you end up looking like a lobster after the first rays. So far, nothing new.

Today we're going to try to tell you at least one thing you don't know about the only invention that prevents all of that: sunscreens.

WHAT DOES SPF MEAN?

The SPF (Sun Protection Factor) measures protection against UVB rays, which cause sunburn (B for “Burn”) 🔥).

The number next to it indicates how much longer it takes to burn using sunscreen compared to not using it. For example: if you have very pale skin, like a scared vampire, and without protection you burn in 1 minute; with SPF 20 it would take approximately 20 times longer (20 minutes).

But there are two important nuances here:

SPF does not measure protection against UVA rays, Those that age the skin (A for Aging). That's why, beyond the number, there's a key word you should always look for: “broad spectrum”. This is what ensures protection against UVA + UVB rays.
It is calculated under laboratory conditions, not in your day-to-day life.

SPF IN THE LABORATORY VS SPF IN 'REAL LIFE'

In order for a product to be able to indicate SPF30 or SPF50+, it must pass a test in an independent laboratory.

The problem is that this test takes place under fairly controlled conditions: no sweating, no touching your face, no showering, no constant movement. In real life, all of that does happen. That's why dermatologists insist so much on reapplication: it's not just a whim, it's because the protection wears off over time.

This is where many protectors fall short: they perform well in the lab, but don't fit into real-world routines.

THE CHALLENGE: A PLEASANT PROTECTION

Formulating a high SPF isn't just about "increasing the number." It needs to be done without the experience becoming a chore, especially if you have to reapply it several times a day.

As of today, the options can be summarized as follows:

You use filters

MINERALS (PHYSICAL)

CHEMICALS

COMBINED

WHAT IT CONTRIBUTES

Easy to formulate, tolerated by most skin types

Lightweight textures, invisible finish.

Balance between protection and sensory experience.

WEAK POINT

They leave your face white and a feeling of mass on your face.

They may be more reactive on sensitive skin.

They require more formulation work.

WHAT TO LOOK FOR IN A GOOD SPF50+

There are several points that do make a difference:

Broad spectrum protection (UVA + UVB). Undisputed.
A texture that suits you, that matches what you already use and know you'll use again.
A finish that doesn't detract aesthetically. And if it improves the appearance of the skin, even better.
Additional benefits, such as niacinamide or antioxidants, that add up in the long term.

THE SIWON APPROACH: PROTECTION THAT ADDS UP

In our case, when we formulate a sunscreen, the goal is not only to meet SPF requirements, but to do so in a formula that fits into your daily life.

Therefore, in the new Handsomefyer Sun SPF50 We have worked on:

Broad spectrum and reinforced protection.
Optimized combination of filters.
Light texture, no mask effect.
A finish that instantly improves the appearance of the skin.
Ingredients such as niacinamide, hyaluronic acid or ginseng

The idea is simple: if you like how it looks and how it feels, it's much easier to use it every day.

TL;DR (FOR FUNCTIONALLY LAZY PEOPLE)

SPF50 protects against UVB, but it's not everything.
Always look for a “broad spectrum”.
Laboratory ≠ real life.
Texture matters more than it seems.
The best protector is the one you use and repeat without thinking twice.
If you're not too lazy to put it on, you're doing well.

P.D. : This week's blog post is sponsored by the restock of Handsomefyer SUN. He's back, with reinforced filters, and he passed the tests with flying colors. Both the theoretical (the lab test) and the practical (the real-life test).
