Chemical Sunscreens vs. Mineral Sunscreens

There are two types of UV rays we need to protect against:

1. UVA rays: These harmful rays penetrate deep into the skin and cause premature aging and skin damage.

2. UVB rays: These affect the outer layer of skin and are the primary cause of sunburn.

   
   

Both chemical and mineral sunscreens protect against these harmful rays, but they work in different ways.

Chemical Sunscreens: The Absorbers

Chemical sunscreens work by absorbing UV radiation. They contain organic (carbon-based) compounds that undergo a chemical reaction when exposed to UV light. This reaction transforms the UV radiation into heat, which is then released from the skin.

Common ingredients in chemical sunscreens include:

• Oxybenzone

• Avobenzone

• Octisalate

• Octocrylene

• Homosalate

• Octinoxate

The active ingredients in mineral sunscreens are:

• Zinc Oxide

• Titanium Dioxide

Humans have used these inorganic compounds for sun protection for thousands of years.

Pros of Mineral Sunscreens

• Immediate protection: Unlike chemical sunscreens, mineral sunscreens start working immediately.

• Less irritation: Mineral sunscreens are generally better for sensitive skin as they're less likely to cause irritation or allergic reactions.

• Longer shelf life: Mineral sunscreens' inorganic ingredients are more stable and less likely to degrade over time.

• Broad-Spectrum protection: Both zinc oxide and titanium dioxide protect against UVA and UVB rays.

• Reef-safe: Mineral sunscreens are safe for coral reefs and marine life, making them a more eco-friendly choice.

Cons of Mineral Sunscreens

• White cast: Traditional mineral sunscreens can leave a white tint on the skin, particularly on darker skin tones.

• Thicker texture: Mineral sunscreens are thicker and can feel heavier on the skin. But our Botanical Facial Cleanser can wash away a full face of sunscreen after a day in the sun!

• Can be drying: Some mineral sunscreens have a drying effect, which may not be ideal for dry or mature skin.

• May transfer onto clothes: Mineral sunscreens can sometimes rub off clothing because they sit on top of the skin.

Making the Right Choice for Your Skin

So, which type of sunscreen should you choose? The answer depends on various factors:

• Skin type: Mineral sunscreens might be your best option if you have sensitive skin or are prone to reactions.

• Activity level: If you're active outdoors or going swimming (in a pool!), you might prefer a water-resistant chemical sunscreen.

• Daily use: You may find chemical sunscreens more appealing for everyday wear under makeup.

• Environmental concerns: If you're worried about the impact on marine life, opt for reef-safe mineral sunscreens.

• Skin tone: If you have a darker skin tone and are concerned about a white cast, consider chemical sunscreens or look for specially formulated mineral options.

The Future of Sun Protection

As we look toward the future, the line between chemical and mineral sunscreens may start to blur. We're seeing more hybrid formulas combining both active ingredients to maximize protection and minimize drawbacks.

At Eavara, we're excited about the potential of natural ingredients to boost the efficacy of mineral sunscreens. Ingredients like red algae, which has natural UV-protective properties, or green tea extract, known for its antioxidant benefits, can complement the protection offered by zinc oxide.

We're also keeping a close eye on emerging technologies like DNA repair enzymes, which may be able to help reverse sun damage, and oral sunscreen supplements, which aim to boost the body's natural defense against UV radiation from the inside out.
