Updated: Jun 21, 2023

Sunscreen is an essential component of a healthy skincare routine. It helps protect our skin from harmful ultraviolet (UV) rays, which can cause sunburn, premature aging, and increase the risk of skin cancer.


In this article, we will discuss:

  • Who should use sunscreen?

  • The different types available

  • When and where to apply it?

  • How much to use?

  • Reasons why sunscreen is crucial for maintaining healthy skin?

  • Are mineral sunscreens better?

  • Sunscreen VS Sunblock

Who should use sunscreen?

In short, everyone should use sunscreen, regardless of their age, gender, or skin color. UV rays can damage the skin and lead to various health concerns. Even individuals with darker skin tones, who are less prone to sunburn, are still at risk of developing sun-related issues. Therefore, it is crucial for everyone to make sunscreen a part of their daily skincare routine.

What type of sunscreen should I use?

When choosing a sunscreen, there are two main types to consider: chemical sunscreens and mineral sunscreens. Chemical sunscreens work by absorbing UV rays, while physical sunscreens create a barrier on the skin's surface to reflect and scatter the rays. Both types offer effective protection, but individuals with sensitive skin may prefer physical sunscreens, as they are less likely to cause irritation.

It is also important to select a broad-spectrum sunscreen that protects against both UVA and UVB rays and has a sun protection factor (SPF) of 30 or higher.

Choosing the Right Sunscreen for Your Skin:

When selecting a sunscreen, it is important to consider factors such as your skin type and sensitivity.

  • For oily or acne-prone skin, opt for oil-free or non-comedogenic formulas.

  • Dry skin benefits from sunscreens with moisturizing properties.

  • Those with sensitive skin should choose sunscreens labeled "hypoallergenic" or "fragrance-free."

Additionally, consider your lifestyle and choose a sunscreen that suits your activities, whether you need water-resistant or sweat-resistant formulations.

When should I apply sunscreen?

To ensure maximum protection, it is recommended to apply sunscreen at least 15 to 30 minutes before going outdoors. This allows the sunscreen to be absorbed into the skin and create a protective barrier. Additionally, sunscreen should be reapplied every two hours or immediately after swimming or excessive sweating. Even on cloudy or overcast days, UV rays can still penetrate through the clouds, so sunscreen application is necessary.

Where should I apply sunscreen?

Sunscreen should be applied to all exposed areas of the body. It is important not to forget commonly overlooked areas such as the ears, back of the neck, lips, and the tops of the feet. Don't neglect the delicate skin on your face and apply sunscreen generously to ensure comprehensive coverage.

How much sunscreen should I use?

The general guideline is to use about one ounce (30 milliliters) of sunscreen, which is equivalent to a shot glass full, to cover the entire body. However, the amount may vary depending on the individual's body size. It is crucial to apply a sufficient amount to achieve the desired level of protection.


Why should I use sunscreen?

Using sunscreen offers numerous benefits for your skin and overall health:

1. Protection against sunburn: Sunburn is not only painful but also increases the risk of skin cancer. Sunscreen helps prevent sunburn by shielding the skin from harmful UV rays. 2. Reduced risk of skin cancer: Prolonged exposure to the sun without protection can lead to skin cancer. Regular sunscreen use can significantly lower the risk of developing various forms of skin cancer, including melanoma, the most dangerous type. 3. Prevention of premature aging: UV rays contribute to premature aging signs such as wrinkles, fine lines, and age spots. By using sunscreen daily, you can help maintain youthful-looking skin and prevent the visible signs of aging. 4. Protection against UV-induced skin damage: UV rays can cause DNA damage in the skin cells, leading to long-term effects such as weakened immunity and impaired skin barrier function. Sunscreen acts as a barrier, minimizing the damage caused by UV radiation.

Are mineral sunscreens better?

If you have sensitive skin or frequently experience reactions to skincare products, mineral sunscreen might be a better choice for you. Some individuals find that chemical sunscreens can cause stinging or irritation.

Sunscreen VS Sunblock

Sunscreen and sunblock, though sometimes used interchangeably, have slight differences in their mechanisms of action. Sunscreen works by absorbing or scattering UV rays, utilizing organic or inorganic compounds as filters to reduce the penetration of radiation into the skin. It allows some UV radiation to reach the skin but diminishes its harmful effects.

Sunblock, on the other hand, physically blocks the sun's rays using mineral compounds like titanium dioxide and zinc oxide, creating a barrier on the skin's surface that reflects and scatters UV radiation. Sunblock provides immediate and complete protection by physically blocking the sun.

Ultimately, both sunscreen and sunblock play vital roles in shielding the skin from UV radiation, and the choice between the two depends on personal preference and specific needs.

Sunscreen is an essential tool for protecting your skin from the harmful effects of UV rays. Regardless of your skin tone or the weather conditions, incorporating sunscreen into your daily routine is crucial. By choosing the right type of sunscreen.
