Is SPF a Hoax?
The sun, our glowing astrological powerhouse, is something most of us look forward to; whether for its warmth, energy, or mood-boosting effects. But have you ever stopped to wonder what it actually does to us internally? Some argue that the sun is a natural healer, an essential provider of vitamin D. Others warn that UV radiation can wreak havoc on our skin, leading to hyperpigmentation, wrinkles, and long-term damage. The truth? Neither side is entirely wrong.
So, where does that leave SPF? Should we be wearing sunscreen daily, or is SPF just another marketing gimmick? Let’s break it all down, from the science of UV rays to the types of sunscreens available, so you can make an informed decision for your skincare routine.
The Truth About the Sun + UV Rays
The sun emits ultraviolet (UV) radiation every day in two primary forms: UVA and UVB.
- UVA (Aging Rays): These rays penetrate deep into the skin, accelerating premature aging, fine lines, and wrinkles.
- UVB (Burning Rays): These are shorter rays that hit the skin’s surface, causing sunburn and direct cellular damage.
While sunlight has undeniable benefits, excessive UV exposure can contribute to premature aging, skin conditions, and even skin cancer. Protecting your skin, especially delicate areas like your face, is crucial for long-term skin health.
A common myth? That sunscreen is only necessary in the summer. False! The sun shines year-round, and UVA rays are so strong that they penetrate clouds, windows, and even clothing. This means your skin is still exposed even when it’s cloudy or you’re sitting indoors by a window.
What SPF Actually Does (and Doesn’t Do)
SPF stands for Sun Protection Factor, which measures how well a sunscreen protects against UVB rays (the ones responsible for sunburn). SPF levels range from 10 to 100, but here’s a little-known fact: once you go beyond SPF 30, the increase in protection is minimal.. only about 1-2% more effectiveness.
The key? Look for “broad-spectrum” sunscreen, which protects against both UVA and UVB rays.
Choosing the Right SPF for Your Skin
Your skin type (Fitzpatrick type) plays a major role in determining what SPF you need. Here’s why:
- Darker skin tones naturally produce more melanin, offering some built-in sun protection. An SPF 30 is usually sufficient.
- Lighter skin tones have less melanin and are more prone to sunburn. They benefit from SPF 50 and up for extra defense.
Chemical vs Mineral Sunscreens: Which One is Better?
There are two main types of sunscreen:
1. Chemical Sunscreens: These absorb into the skin and neutralize UV radiation before it can cause damage. They often contain added skincare benefits like hydration but may not be ideal for those with an impaired barrier.
These Sunscreens have a type of chemical UV filter with active ingredients like oxybenzone, avobenzone, ocisalate, and more.
My favorite chemical sunscreen is Dynamic Skin Recovery by Dermalogica, it absorbs into the skin nicely with no film left over. Dynamic Skin Recovery works really well for aging skin and dry to normal skin types.
2. Mineral (Physical) Sunscreens: These sit on top of the skin, physically blocking UV rays. They are best for sensitive skin, children, and those looking for more natural ingredients. While traditional formulas leave a white cast, newer versions include tints to blend seamlessly.
These Sunscreens are formulated with two key ingredients, zinc oxide and titanium oxide which are both recognized as safe and effective by the FDA.
My favorite mineral sunscreen is the Clarity RX Physical Skin Defense tinted sunscreen. This is a newer version of the formula so it leaves a nicer seamless finish. Physical Skin Defense works well for normal or sensitive skin types.
So, Is Sunscreen Really Necessary?
Yes, sunscreen is necessary, but not all sunscreens are created equal.
The sun is a beautiful, powerful force that nourishes our planet and plays a key role in our health. But direct and prolonged exposure to UV rays can do more harm than good if we don’t take precautions. Using sunscreen with the right SPF for your skin type, and choosing a formula that works for you, is one of the best ways to protect your skin while still enjoying the benefits of sunlight.
The argument lies in the efficacy of the sunscreens. How much active ingredients can our bodies tolerate? The FDA has banned two chemical UV filters and is still researching safe formulations, so it’s up to you.
