Mineral vs Chemical Sunscreen: How They Differ & Which Is Better

Sunscreen this, sunscreen that! We bet by now you must have understood that not wearing sunscreen is seen as a crime in the skincare world. And why shouldn’t it be? Sunscreen is one powerful skincare product for women that can reduce dark spots, hyperpigmentation, and fine lines by protecting the skin from harmful ultraviolet (UV) rays of the sun. 

The benefits of sunscreen on face are undeniable. But, when it comes to picking the right one for yourself, you get overwhelmed. Well, we don’t blame you! With so many options available it does get difficult, especially between mineral (also referred to as physical) or chemical sunscreen. If you are also wondering what’s the difference between physical and chemical sunscreen then we’ve got you covered. Below we have delved deeper into physical vs chemical sunscreen, which one is better, its benefits, and its ingredients. 

Mineral VS Chemical Sunscreen: Does It Matter Which One I Use?

Yes, it does matter. Mineral sunscreens contain physical blockers like zinc oxide or titanium dioxide and sit on the skin’s surface. These types of sunscreens are also commonly known as physical sunscreen. Chemical sunscreens, on the other hand, absorb UV rays, convert them into heat, and then release the heat from the skin. Both provide protection, but some may prefer mineral sunscreens for sensitive skin, as they often cause less irritation.

That said, the choice between physical or chemical sunscreen depends on personal preference, skin type, and any specific sensitivities or concerns you may have. It’s crucial to use sunscreen for face and other body parts regularly and reapply it for effective protection.

How Do Chemical & Mineral Sunscreens Work?

We know both types of sunscreen are essential. But how do they work? 

Mineral Sunscreens 

These sunscreens typically contain zinc oxide, titanium dioxide, or both. These minerals sit on the skin’s surface and act as a physical barrier, reflecting and scattering UV rays, hence the name physical sunscreen. It provides broad-spectrum protection against both UVA and UVB rays and is ideal for sensitive skin as they are likely to cause less irritation. 

Chemical Sunscreens

It has compounds like avobenzone, octocrylene, or oxybenzone. Chemical sunscreens absorb UV rays, convert them into heat, and then release the heat from the skin. Just like mineral sunscreen, it offers broad-spectrum protection but may need to be reapplied more frequently as it can break down over time. People who prefer a lightweight feel often go for chemical sunscreens as they are often thinner and easier to apply.

What Is A Mineral Sunscreen?

If you are still wondering what mineral sunscreen is and why mineral sunscreen is called a physical sunscreen then you’ve come to the right place. Mineral sunscreens have active ingredients, typically zinc oxide or titanium dioxide, that act as physical blockers. as their active ingredients. These minerals create a protective layer on the skin’s surface that reflects and scatters ultraviolet (UV) rays from the sun, thus the name physical sunscreen.  

Pros Of Mineral Sunscreen

Here are some pros of mineral sunscreen –

1. Mineral sunscreens protect against both UVA and UVB rays. This makes them effective as sunscreen for sunburn and long-term skin damage.

2. Zinc oxide and titanium dioxide, the main ingredients in mineral sunscreens, are less likely to irritate. This makes them suitable for sensitive or allergy-prone skin.

3. Mineral sunscreens start protecting the skin as soon as they are applied

4. Mineral sunscreens are photostable, meaning they do not degrade or lose effectiveness when exposed to sunlight. 

5. Mineral sunscreens do surface do not penetrate deeply into the skin. This potentially reduces the risk of skin irritation or systemic absorption.

6. Due to their gentle nature, mineral sunscreens are often recommended for children and individuals with delicate skin.

7. Mineral sunscreens typically have a longer shelf life compared to some chemical sunscreens, maintaining their effectiveness over time.

Cons Of Mineral Sunscreen

While mineral sunscreens have several benefits, they also come with some drawbacks:

1. Mineral sunscreens can leave a noticeable white cast on the skin, which may not be aesthetically pleasing.

2. Some people find that mineral sunscreens have a thicker consistency and can feel heavier on the skin compared to chemical sunscreens.

3. Some people might tend to struggle with achieving an even application of mineral sunscreen.

4. Mineral sunscreens might be less water-resistant compared to certain chemical sunscreens, which can be a concern during water-related activities.

5. Zinc oxide in sunscreen offers good UVA protection, titanium dioxide may be less effective against some UVA rays. 

6. While mineral sunscreens are generally well-tolerated, some individuals may still experience skin sensitivity or allergies to the mineral ingredients.

Active Ingredients In Mineral Sunscreen

Mineral sunscreens have two active ingredients, zinc oxide and titanium dioxide. Zinc oxide is a white, powdery mineral that is effective against both UVA and UVB rays. It sits on the skin and forms a physical barrier, preventing the rays from penetrating. Titanium dioxide in sunscreen, on the other hand, works similarly to zinc oxide sunscreen. It’s also effective against UVB rays but may need additional coating or formulation for optimal UVA protection. 

What Is A Chemical Sunscreen?

Chemical sunscreens use organic (carbon-based) compounds as their active ingredients to protect the skin from the sun’s ultraviolet (UV) radiation. The active ingredients in chemical sunscreens, such as avobenzone, octocrylene, octinoxate, and oxybenzone, are designed to absorb UV radiation. The main difference between mineral and chemical sunscreen is that in chemical sunscreen the compounds undergo a chemical reaction when exposed to UV rays, transforming the absorbed energy into heat.

Pros Of Chemical Sunscreens

There are several chemical sunscreens and here they are – 

1. Chemical sunscreens often leave no white cast on the skin, unlike most mineral sunscreens. 

2. Chemical sunscreens typically have a lighter and smoother texture, making them easy to apply and blend into the skin.

4. Chemical sunscreens are available in various formulations, including lotions, creams, gels, mists, and sprays, offering tons of options. Sunscreen mists are often useful for applying on the entire body and not just the face.

5. Many chemical sunscreens are formulated to be water-resistant, providing effective protection during water-related activities–an absolutely perfect fit for your monsoon skincare routine. 

6. Chemical sunscreens are absorbed into the skin relatively quickly, allowing for rapid protection after application.

7. Chemical sunscreens are available in a wide range of SPF levels, catering to different sun protection needs.

Cons Of Chemical Sunscreens

Chemical sunscreens have some drawbacks:

1. Some people may experience skin irritation or allergic reactions to the chemical compounds in these sunscreens. 

2. Chemical sunscreens are absorbed into the skin. Now these absorbed compounds can enter the bloodstream, causing long-term issues. 

3. Chemical sunscreens often take some time, usually about 15-30 minutes, to be absorbed into the skin before they become effective. 

4. Typically, the chemical reaction that occurs on the skin to convert UV radiation into heat can sometimes lead to a feeling of warmth on the skin, which may be uncomfortable for some individuals.

5. Individuals with sensitive skin may find that some chemical sunscreens cause irritation, redness, or stinging. In such cases, mineral sunscreens might be a preferred option.

9. Some chemical sunscreens may contain ingredients that can stain clothing.

Active Ingredients In Chemical Sunscreens

Chemical sunscreens contain various active ingredients that absorb UV radiation. Common chemical sunscreen ingredients include avobenzone which is effective against UVA rays, octocrylene which is often used to stabilise avobenzone and contributes to UVB protection, octinoxate (octyl Methoxycinnamate) which primarily absorbs UVB rays, making it a common ingredient in sunscreens to protect against sunburn. It also contains homosalate which offers UVB protection and is often used in combination with other chemical sunscreen ingredients. Octisalate, octocrylene, Mexoryl SX (ecamsule), and Tinosorb S and Tinosorb M, are some other ingredients present in chemical sunscreen.

What’s The Difference Between Mineral And Chemical Sunscreen?

The primary differences between mineral and chemical sunscreens lie in their active ingredients and how they protect the skin from the sun’s ultraviolet (UV) radiation. While mineral sunscreen contains physical blockers like zinc oxide or titanium dioxide, chemical sunscreen contains organic compounds like avobenzone, octocrylene, and oxybenzone. Mineral sunscreen forms a protective barrier on the skin’s surface, reflecting and scattering UV rays whereas Absorbs UV rays and transforms them into heat, releasing it from the skin. Chemical sunscreens are a perfect pick for people with sensitive skin whereas, chemical sunscreens might cause some irritation. Lastly, mineral sunscreens can leave a white cast but chemical sunscreen feels transparent on the skin.

Physical Spf VS Chemical Spf: Which One Should I Use?

Before we delve into physical SPF vs chemical SPF, let’s understand SPF sunscreen meaning first. SPF stands for Sun Protection Factor which measures a sunscreen’s ability to protect the skin from the sun’s harmful UV (ultraviolet) rays. The SPF value indicates the level of protection against UVB rays, which are primarily responsible for causing sunburn.

Now, the choice between a physical SPF and a chemical SPF depends on personal preferences, skin type, and any specific skin conditions. Mineral sunscreen are generally better for sensitive skin, provides immediate protection upon application, and reflects UV rays, suitable for those with heat-sensitive skin. However, it may leave a white cast and can feel heavier on the skin. Chemical SPF is often lighter on the skin and absorbs quickly without leaving a white cast. It may offer broader protection against a range of UV wavelengths. However, some individuals may experience skin sensitivity or irritation and it requires about 20 minutes to become effective after application.

In short, if you have sensitive skin, physical sunscreen might be a good choice. If you prefer a lighter feel, a chemical sunscreen could be suitable. Keep in mind factors like your skin’s response, any allergies, and daily comfort when making your decision.

Conclusion

If you have sensitive skin, a physical sunscreen might be a good choice. If you prefer a lighter feel, a chemical sunscreen could be suitable. But remember, no sunscreen can work for you unless you use it consistently, even on days when you think you don’t require wearing one.
