Welcome to the ultimate guide to better sunscreen
Winter’s fading… and the sun is making a comeback. Before you know it, those long-lost sunny days will be here — and with them, the need for a sunscreen you can truly trust.
But let’s be honest: not all sunscreens are created equal. Between chemical vs. physical filters, SPF 30 or 50, and labels that promise the world, choosing the right one for you and your family is a bit overwhelming — especially if you’re looking for something that has it all: effective, biodegradable, and truly safe.
That’s why we’ve created the ultimate guide for Spring 2025 — so you can feel confident and protected in the sun. From understanding filters to knowing what ingredients to avoid, here’s everything you need to know to find your perfect sunscreen match.
Physical vs. Chemical Filters: Which is Better?
When it comes to choosing the right sunscreen, one of the biggest questions is: should you go for physical mineral or chemical filters? The answer depends on your skin type, lifestyle, and what you’re looking to avoid.
- Physical (or mineral) filters work by creating a natural barrier that reflects UV rays from the moment of application. They don’t degrade with sun exposure, making them a more stable and long-lasting option. Dermatologists often recommend mineral filters for sensitive skin, allergy-prone skin, and children, thanks to their gentle and reliable protection.
- Chemical filters, on the other hand, absorb UV radiation and transform it into heat. Their effectiveness depends on the wavelength of the light, meaning some parts of your skin may remain partially unprotected. These filters often contain controversial ingredients and are not biodegradable, which is a concern for both your skin and the environment.
So, which one should you choose? If you’re looking for safe, eco-conscious, and skin-friendly sun protection, mineral filters are the way to go — especially for daily facial use, kids, and anyone with reactive skin.
The Hidden Gem of Sunscreen: Biological Filters
You’ve heard of physical and chemical filters — but there’s a third player in the sun protection game that deserves the spotlight: biological filters.
These are powerful antioxidant ingredients that work behind the scenes to neutralize free radicals — the unstable molecules that accelerate skin aging and cellular damage after sun exposure. While they don’t block UV rays directly, they enhance the overall effectiveness of your sunscreen by supporting your skin’s own defense systems.
Biological filters are never used alone. Instead, they’re added to physical or chemical filters to create a more complete shield — one that not only protects, but also repairs and strengthens your skin.
Think of them as your sunscreen’s secret weapon: boosting protection, calming inflammation, and helping your skin recover from the oxidative stress caused by the sun.
SPF 30 vs. SPF 50: How Long Does It Last and Which One Do You Really Need?
All sunscreens will protect your skin from UVB rays, meaning the type of ultraviolet radiation responsible for sunburn and direct skin damage. And when it comes to UVB protection, the math is simple: the higher the SPF (Sun Protection Factor), the more UVB rays are filtered out.
The SPF number gives you an idea of how long you can stay in the sun as compared to unprotected skin. For example, SPF 30 means your skin takes 30 times longer to redden than if you weren’t wearing any sunscreen at all. This is how it goes:
- SPF 30 blocks about 97% of UVB rays. This is a great option for daily sunscreen use, moderate sun exposure, or if you prefer a more breathable texture.
- SPF 50 blocks around 98% of UVB rays. Ideal for fair or reactive skin or those longer days in the sun.
- SPF 50+ offers up to 99% protection. Often recommended for very sensitive skin, sun allergies, or sun protection for babies and young children.
But Wait — What About UVA Rays?
UVB isn’t the whole story. There’s also UVA radiation, which penetrates deeper into the skin and is a major contributor to skin cancer. Unlike UVB, UVA protection isn’t reflected in the SPF number, so it’s important to look for a “broad-spectrum” sunscreen that shields you from both.
Tip: If you're concerned about hyperpigmentation, melasma, or dark spots, using a high-SPF, broad-spectrum sunscreen and reapplying it consistently is key. Even minimal exposure can trigger pigmentation — so protecting your skin every day is essential for keeping your tone even and healthy.
Tinted or Untinted Sunscreen: Which One Is Right for You?
Before you decide, here’s the most important thing to know: both tinted and untinted sunscreens offer the same level of sun protection. It’s SPF what determines your defense from UV rays , no the color. So now you know, and can choose what you like best. Here is what we recommend:
- Tinted Sunscreen / CC Cream: Worried about white cast? Our tinted mineral sunscreen is your go-to if you want a natural glow and an even skin tone — no makeup needed. Perfect for everyday use, it helps blur imperfections, balance your complexion, and leaves you with that fresh, “your skin but better” finish.
- No color sunscreen: Prefer something invisible? Our untinted mineral sunscreen is 100% recommended if you’re doing sports, have sensitive skin, or need a formula that won’t stain your clothes. If you go for DHYVANA we combine our minerals to leave minimal white cast

Bonus: If your sunscreen contains biological filters in addition to physical ones, you’ll get extra benefits beyond UV protection. Depending on the ingredients, they can offer antioxidant, hydrating, and soothing properties, helping to strengthen your skin’s long-term health.
What Are Biological Filters and Why Are They Key to Your Sun Protection?
We promised you a hidden gem: biological filters can make all the difference when it comes to your skin’s long-term health.
We are talking about antioxidant-rich ingredients that enhance sun protection by helping to neutralize free radicals generated by sun exposure. When included in sunscreen formulas, they strengthen your skin’s natural defense mechanisms and offer added benefits beyond just UV protection.
Sounds good? Find out which ones we are using and why:
- Our SPF 30 Mineral Facial Sunscreen is ideal for everyday use. It contains Raspberry Seed Oil, a powerful antioxidant that helps prevent free radical damage, keeps the skin hydrated, and protects against premature aging.
- The SPF 50 Mineral Facial Sunscreen is designed for higher sun exposure. Our formula includes botanical extracts with anti-inflammatory properties, perfect for preventing cellular damage and shielding the skin during intense sun and heat.
- Our unique SPF 50+ Mineral Sunscreen for Babies and Children offers the highest level of protection for sensitive skin. It features Calendula Oil and other soothing botanical extracts, providing extra softness and care for the most delicate skin — including babies and little ones.
All DHYVANA sunscreens are enriched with Hyaluronic Acid and Aloe Vera, which hydrate, regenerate, and strengthen the skin barrier — supporting a healthy microbiome and balanced skin.
Are Biological Filters the Same as Biodegradable Filters?
Not quite — they might sound similar, but they refer to two very different things. Both are important when it comes to choosing a healthier, more eco-conscious sunscreen, but they serve distinct purposes:
- Biological filters are natural antioxidant ingredients (plant-based extracts) that help neutralize free radicals, reinforce the skin’s natural defenses, and support long-term skin health. They help neutralize free radicals support the skin’s natural defenses and promote healthier, more resilient skin — especially after sun exposure. Think of them as your sunscreen’s inner support system.
- Biodegradable filters are typically formulated with mineral (or physical) filters such as non-nano zinc oxide and titanium dioxide. This means they don’t penetrate the skin or accumulate in marine organisms — making them a much safer choice for both your body and the environment. Unlike many chemical filters, which have been linked to coral bleaching and water pollution, non-nano mineral filters remain on the skin’s surface and don’t create toxic residues. As a result, biodegradable sunscreens help preserve coral reefs, protect marine biodiversity, and reduce the contamination of rivers, seas, and coastal ecosystems.

Sun Protection for Children and Babies
Children’s skin is thinner and more sensitive, which makes it less equipped to defend itself against UV radiation. On top of that, excessive sun exposure during childhood can increase the risk of long-term skin damage.
That’s why dermatologists recommend using sunscreens with physical (mineral) filters for babies and children. These create a natural barrier on the skin’s surface without being absorbed — offering safe, gentle, and effective protection from the very first day at the beach (or the park!).
What Is the Most Recommended Sunscreen by Dermatologists?
Dermatologists agree: the best sunscreen is the one that offers maximum protection against both UVB and UVA rays — without compromising your skin’s health. And if you go one step further and choose a natural formula, you’re also doing the planet a favor. Win-win.
- Broad-spectrum protection – Shields your skin from both UVA and UVB rays.
- Biodegradable and environmentally safe – Free from chemical filters and nanoparticles.
- Lightweight, fast-absorbing texture – Essential for daily wear and comfort.
- No fragrance or irritating ingredients – Especially important for sensitive or allergy-prone skin.
- Hydrating and antioxidant-rich – With ingredients like Hyaluronic Acid and botanical extracts that nourish and protect.
- Water- and sweat-resistant – Ideal for outdoor activities and long sun exposure.
If you’re looking for the best protection for your skin, choose a sunscreen that truly cares for you. Opt for a mineral formula, free from harsh chemicals and packed with natural ingredients — one that not only shields you from the sun but also nourishes and hydrates your skin, day after day.
