Just something that’s Good to know…

As the sun peeks out from behind the clouds, inviting us to step outside, we find ourselves facing an old debate about sunscreens. On one side, there's the appeal of chemical sunscreens, boasting easy application and nearly invisible protection. But hidden concerns about potential harm to our health and the environment linger in the background. On the other side, natural sunscreens stand strong, relying on minerals and plants to shield us from the sun's rays. With promises of gentle care and eco-friendly ingredients, they suggest a more wholesome approach to sun protection. As these opposing views clash, each vies for our trust, leaving us to wonder: which one will we choose for our sunny adventures?

Practical tips and considerations for choosing the most suitable sunscreen based on individual needs, preferences, and skin types

Let’s get right to it and explore the main differences between natural and chemical sunscreens, which, by the end of this blog, should give you a better idea of what direction you may want to consider for your sunscreen needs. To begin, the primary difference between natural sunscreen and chemical-based sunscreen lies in their active ingredients and how they work to protect the skin from the sun's harmful UV rays.

Natural sunscreens, also known as physical or mineral sunscreens, contain active mineral ingredients such as zinc oxide and titanium dioxide. These minerals create a physical barrier on the skin's surface that reflects and scatters UV rays away from the skin. Essentially, they act as a shield, providing broad-spectrum protection against both UVA and UVB rays.

Chemical-based sunscreens contain organic (carbon-based) compounds such as avobenzone, octocrylene, homosalate, Octinoxate (Octyl Methoxycinnamate), Oxybenzone (Benzophenone-3), Octisalate (Octyl Salicylate) among others. These chemicals work by absorbing UV radiation and converting it into heat, which is then released from the skin. Chemical sunscreens typically need to be absorbed into the skin to be effective.

Natural sunscreens and chemical-based sunscreens both have their own set of advantages and disadvantages. Here's a breakdown:

Natural Sunscreens:

Pros:

1. Gentler on the Skin: Natural sunscreens often contain mineral ingredients like zinc oxide and titanium dioxide, which sit on the skin's surface and reflect or scatter UV rays away from the skin. These ingredients are less likely to cause irritation or allergic reactions compared to some chemical filters.

2. Broad Spectrum Protection: Many natural sunscreens provide broad-spectrum protection against both UVA and UVB rays. They work by reflecting and scattering UV radiation away from the skin, acting as physical barriers.

3. Environmentally Friendly: Mineral-based sunscreens are generally considered more environmentally friendly because they don't contain certain chemicals like oxybenzone and octinoxate, which have been found to harm coral reefs. They are biodegradable and do not contribute to coral bleaching or harm marine ecosystems when washed off into the ocean.

4. Immediate Effectiveness: Natural sunscreens typically start protecting the skin as soon as they are applied, unlike some chemical sunscreens that require a waiting period before becoming effective.

5. Non-Comedogenic: Zinc oxide and titanium dioxide are non-comedogenic, meaning they are less likely to clog pores or exacerbate acne-prone skin. They are suitable for use on the face and body without causing breakouts.

6. Long-Lasting Protection: Mineral sunscreens tend to provide longer-lasting protection compared to some chemical sunscreens, as they are not as prone to breaking down or degrading upon sun exposure.

7. Stable Formulation: Zinc oxide and titanium dioxide are photostable, meaning they do not degrade when exposed to sunlight. This stability ensures that the sunscreen remains effective for longer periods, even during prolonged sun exposure.

8. No Hormone Disruption: Unlike some chemical sunscreen ingredients like oxybenzone and octinoxate, zinc oxide and titanium dioxide do not interfere with hormone levels in the body. They are considered safer alternatives for individuals concerned about endocrine disruption.
   

Cons:

1. White Residue: Some natural sunscreens leave a white residue on the skin due to the mineral ingredients. While newer formulations have improved in this regard, it can still be a concern for some users, especially those with darker skin tones.

2. Thicker Consistency: Mineral sunscreens tend to have a thicker consistency, which can feel heavy or greasy on the skin.

3. Water Resistance: Natural sunscreens may be less water-resistant compared to some chemical sunscreens, requiring more frequent reapplication, especially after swimming or sweating.

4. Limited SPF Options: Natural sunscreens may have limited options in terms of SPF levels compared to chemical sunscreens.
   

Chemical-Based Sunscreens:

Pros:

1. Lightweight Consistency: Chemical sunscreens often have a lighter consistency compared to mineral sunscreens, making them more comfortable to wear, especially for daily use.

2. No White Residue: Chemical sunscreens typically do not leave a white residue on the skin, making them more aesthetically appealing, particularly for people with darker skin tones.

3. High SPF Options: Chemical sunscreens offer a wide range of SPF options, including high SPF levels for extended sun protection.

4. Water Resistance: Many chemical sunscreens are formulated to be water-resistant, providing longer-lasting protection during activities like swimming or exercising.

5. Ease of Application: Chemical sunscreens tend to spread more easily and evenly on the skin, requiring less effort during application compared to some mineral sunscreens which can be thicker and may require more rubbing to blend in.

6. Fast Absorption: Chemical sunscreens are typically absorbed quickly into the skin, allowing for faster application and absorption, which can be advantageous for those with busy lifestyles.

Cons:

1. Potential Skin Irritation: Chemical filters, such as oxybenzone and octinoxate, may cause skin irritation or allergic reactions in sensitive individuals.

2. Absorption Concerns: Chemical filters have raised concerns about potential absorption into the bloodstream and their potential impact on hormone levels and overall health.

3. Environmental Impact: Certain chemical filters, like oxybenzone and octinoxate, have been found to be harmful to coral reefs and marine life, leading to bans or restrictions in some regions.

4. Time to Effectiveness: Chemical sunscreens may need to be applied 15-30 minutes before sun exposure to allow the filters to fully activate and provide protection.

You're probably asking, "What ingredients should I look for when buying a natural sunscreen and what ingredients should I avoid?"

When shopping for a natural sunscreen, here are some key ingredients to look for and ones to avoid:

Ingredients to Look For:

Zinc Oxide: Provides broad-spectrum protection against UVA and UVB rays. Look for sunscreens with zinc oxide as the active ingredient, preferably in non-nanoparticle form.

Titanium Dioxide: Another mineral sunscreen ingredient that offers broad-spectrum protection. Like zinc oxide, it is effective against both UVA and UVB rays.

Natural Oils: Ingredients like coconut oil, jojoba oil, shea butter, and avocado oil can provide moisturizing properties and help nourish the skin.

Botanical Extracts: Look for natural extracts such as green tea extract, aloe vera, chamomile, or calendula, which may offer additional antioxidant or soothing benefits for the skin.

Beeswax: Helps to create a protective barrier on the skin and can provide water resistance.

Non-GMO Ingredients: Opt for sunscreens made with non-genetically modified organisms (GMOs) to ensure a more natural and environmentally friendly product.

Mineral-Based Preservatives: Look for natural preservatives such as tocopherol (vitamin E) or plant-derived extracts, which can help extend the shelf life of the sunscreen without the use of synthetic chemicals.

Ingredients to Avoid:

Oxybenzone: A chemical sunscreen ingredient that has been linked to hormone disruption and allergic reactions. Avoid sunscreens containing oxybenzone, especially if you have sensitive skin or hormone-related concerns.

Octinoxate (Octyl Methoxycinnamate): Another chemical sunscreen ingredient that may disrupt hormone function and cause skin irritation. Look for alternatives to octinoxate in natural sunscreens.

Homosalate, Octisalate, and Octocrylene: These chemical sunscreen ingredients have been associated with potential hormone disruption and skin irritation. Choose sunscreens without these ingredients if possible.

Parabens: Synthetic preservatives like methylparaben, ethylparaben, propylparaben, and butylparaben are best avoided due to concerns about potential health risks and hormone disruption.

Fragrance: Synthetic fragrances can contain phthalates and other harmful chemicals that may irritate the skin or cause allergic reactions. Opt for fragrance-free or naturally scented sunscreens.

PEGs (Polyethylene Glycols): These petroleum-derived compounds can be found in some sunscreens and may be contaminated with potentially harmful impurities. Look for PEG-free alternatives.

Nanoparticles: While zinc oxide and titanium dioxide are generally considered safe sunscreen ingredients, some people prefer to avoid nanoparticle formulations due to concerns about potential skin penetration and health risks. Look for non-nanoparticle versions of these ingredients if you have such concerns.

Overall, zinc oxide and titanium dioxide offer effective and safe protection against the sun's harmful rays while being gentle on the skin and the environment. Choosing a natural sunscreen helps protect both your skin and the environment while reducing exposure to potentially harmful chemicals. They are suitable choices for individuals seeking broad-spectrum sun protection without the potential risks associated with some chemical sunscreen ingredients.

Ultimately, the choice between natural and chemical-based sunscreens depends on individual preferences, skin sensitivities, environmental concerns, and desired sunscreen characteristics such as texture and water resistance.
