Everything You Need to Know About Sunscreen

If you apply only one product to your skin every day, let it be face sunscreen. Why? Because premature skin aging is caused by the sun. Why it's necessary to use sunscreen, how to check if its ingredients are effective and safe, whether sunscreens enter the bloodstream, and if they harm coral reefs, is further discussed in the article.
How to pick the sunscreen

Why the Sun is Dangerous for the Skin

UVA rays lead to premature aging by deeply penetrating and breaking down collagen. UVB rays affect the upper layers of the skin, causing sunburn. Both types of rays can cause tanning, and both have the potential, in the long term, to lead to skin cancer.

Furthermore, the sun is a cause of visible signs of premature aging (wrinkles, dark spots, and loss of elasticity). 80% of all signs of skin aging are caused by its effects. Therefore, a daily application of broad-spectrum SPF 30 should be an essential part of any anti-aging skincare routine. HydroPeptide Solar Defense SPF 30 is an excellent choice, offering protection against both UVA and UVB rays. Its lightweight, non-greasy formula also hydrates the skin, making it perfect for daily use.

Is Sunscreen Considered Necessary in Skincare?

Absolutely. Sunscreen is an essential component of any skincare routine. Its primary function is to protect the skin from harmful UV radiation, which not only prevents sunburn and skin cancer but also delays signs of aging. Dermatologists recommend using face sunscreen daily, regardless of weather conditions, as UV rays can penetrate through clouds and windows, causing skin damage over time. For those seeking reliable protection, Face Reality Ultimate Protection SPF 28 is a great option. It provides broad-spectrum defense while being gentle on the skin, making it suitable for daily use and ensuring your skin stays protected and healthy.

Should I Apply Sunscreen When There is No Sun?

Yes, you should apply sunscreen even on cloudy days and during winter. UV radiation is present year-round and can penetrate through clouds. Up to 80% of UV rays can pass through clouds, causing potential skin damage without direct sunlight. Additionally, UV rays can reflect off surfaces like snow, water, and sand, intensifying their impact. For convenient and effective protection, TIZO Mineral Stick Tinted is an excellent choice. This portable stick offers broad-spectrum protection with a natural tint, making it easy to apply and reapply throughout the day, ensuring your skin stays safeguarded no matter the weather.

How to Understand That Sunscreen is Effective?

The effectiveness of face sunscreen is indicated by its Sun Protection Factor (SPF) and its broad-spectrum label. SPF measures the level of protection against UVB rays. An SPF of 30, for example, means it would take 30 times longer for the skin to burn compared to no protection. A broad-spectrum sunscreen protects against both UVA and UVB rays. Additionally, checking for water resistance is crucial, especially for activities involving water or excessive sweating. For those seeking high protection, IMAGE Skincare Daily Prevention Advanced Smartblend Mineral Moisturizer SPF 75 is an excellent option. It offers advanced sun protection with a high SPF and a mineral-based formula, ensuring your skin is well-protected and hydrated throughout the day.

Why is the Texture of Sunscreen Important?

The texture of sunscreen is vital for its application and effectiveness. A sunscreen that feels heavy, greasy, or sticky may discourage regular use. On the other hand, lightweight, non-greasy formulas are more pleasant to apply and wear, ensuring consistent use. The right texture also ensures even application, which is critical for effective protection. Different skin types may prefer different textures; for example, those with oily skin might opt for a mattifying formula, while those with dry skin might prefer a more hydrating sunscreen.

Which Filters Are Considered the Best?

The best sunscreen filters are those that offer broad-spectrum protection, stability, and minimal skin irritation. Physical (mineral) filters like zinc oxide and titanium dioxide are highly regarded for their safety and effectiveness. They work by reflecting UV rays away from the skin. Chemical filters such as avobenzone, octocrylene, and octinoxate absorb UV radiation and convert it into heat, which is then released from the skin. A combination of physical and chemical filters often provides comprehensive protection.

Are Sunscreens Harming the World's Oceans?

Some chemical filters in sunscreens, like oxybenzone and octinoxate, have been found to harm marine life, particularly coral reefs. These chemicals can contribute to coral bleaching, which weakens the coral and disrupts marine ecosystems. As a result, some regions have banned sunscreens containing these ingredients. Mineral sunscreens with non-nano zinc oxide or titanium dioxide are considered safer for marine life.

For those seeking an eco-friendly option, Murad City Skin Age Defense Broad Spectrum SPF 50 is a great choice. This sunscreen uses mineral filters like zinc oxide and titanium dioxide, which are reef-safe and do not harm coral reefs or marine life. Additionally, it provides broad-spectrum protection against UVA and UVB rays while being environmentally conscious. This makes it an excellent option for those who want effective sun protection without contributing to marine pollution.

What Sun Filters Are There?

Sun filters are broadly categorized into physical and chemical filters. Physical filters, like zinc oxide and titanium dioxide, sit on the skin's surface and reflect UV rays. Chemical filters, such as avobenzone, octocrylene, and homosalate, absorb UV radiation and dissipate it as heat. Each type has its advantages and disadvantages, and many sunscreens combine both types to maximize protection and user comfort.

Which Chemical Filters Have a Good Reputation?

Dermalogica Powerbright Moisturizer SPF50 utilizes a blend of advanced chemical filters to ensure comprehensive sun protection. Among these filters, Avobenzone stands out for its ability to shield against UVA rays effectively, while Octocrylene contributes to stabilizing the formula and adds UVB protection.

Tinosorb S and M are newer filters that provide broad-spectrum protection and are photostable, meaning they don't degrade quickly when exposed to sunlight. These filters are commonly used in European and Asian sunscreens and are gaining popularity worldwide for their superior performance.

What Rules for Using Sunscreen Are Really Relevant?

Key rules for using face sunscreen include:

1. Apply Generously: Use about a teaspoon of sunscreen for the face and a shot glass worth for the body.
2. Reapply Regularly: Reapply every two hours, or immediately after swimming, sweating, or towel drying.
3. Apply Evenly: Ensure even coverage to avoid missed spots.
4. Include All Exposed Areas: Don’t forget ears, neck, hands, and feet. When it comes to protecting the rest of your body, body sunscreens are equally important.
5. Use Year-Round: Apply sunscreen daily, regardless of the season or weather.
6. Check Expiry Dates: Ensure the sunscreen is not expired, as its effectiveness can diminish over time.

In conclusion, sunscreen is an indispensable part of skincare, providing essential protection against harmful UV radiation. By understanding the different types of face sunscreens, their ingredients, and how to use them effectively, individuals can make informed choices that benefit their skin health and the environment.
