When it comes to sun protection, it’s easy to think the higher the SPF, the better. But here at Skyrah Beauty, where we genuinely care about educating our clients and offering honest skincare advice, we like to dig a little deeper.
Because the truth is — more isn’t always more when it comes to sun cream.
We’re proud to work with Environ, a brand we trust completely. They recommend an SPF of 15 — and we know that might surprise a few people, especially when SPF 30 and 50 are plastered all over the shops. But once you understand why, it really makes sense.
There are three types of ultraviolet (UV) rays that reach us from the sun:
UVA – “A” for Ageing These rays go deep into the dermis (the second layer of skin), damaging collagen and elastin. They’re responsible for fine lines, wrinkles, and premature ageing. They’re present all year around — even on cloudy days — and can pass through glass.
UVB – “B” for Burning These rays affect the epidermis (the top layer of skin) and are the ones that cause sunburn. They’re strongest during the sunnier months, especially between 11am and 3pm, when the sun is at its highest and most damaging.
UVC – “C” for Cancer (and fortunately Blocked) These are the most dangerous rays, but the ozone layer blocks them completely. No sunscreen is designed to protect against UVC — which is why protecting the ozone (and your skin) really does matter.
Not many people realise this — but UVA rays can actually destroy Vitamin D in the skin, while UVB helps our bodies produce it naturally.
If we block too much sun exposure with very high SPFs or avoid the sun altogether, we could end up with reduced Vitamin D levels, which are vital for healthy skin, bones, and immune function.
This is the part that surprises most people:
The difference between SPF 15 and 50 is just 4.7% more protection. But to get that tiny extra bit of coverage, we often end up using a lot more chemical filters — which isn’t always the best option for sensitive, reactive, or compromised skin.
Environ believes in working with the skin, not against it. That’s why they created RAD SPF 15 and RAD Shield Mineral SPF 15 — two fantastic options, depending on what your skin needs.
A light, creamy formula that combines chemical and physical filters with antioxidant power.
Key ingredients and benefits:
A lightweight mineral sunscreen ideal for sensitive or acne-prone skin, offering broad-spectrum protection without any chemical filters.
Both formulas are designed to work with your skin, not overload it, supporting your skin barrier while protecting from environmental aggressors.
We love helping our clients understand why we recommend what we do. It’s not just about selling products — it’s about giving you honest, evidence-based advice that supports your skin long-term.
