We all know that sunscreen is only for outdoors. In this article, we will also discuss sunscreen using tips. But dermatologists say that to keep your skin healthy, you need to wear sunscreen indoors too. This is because not only the harmful rays of the sun but also the light from the screens of various electronic devices can damage the skin. Knowing how to apply sunscreen, which sunscreen is safe for the skin, and how much to apply can prevent signs of aging, wrinkles, and dark spots caused by harmful rays.
Many of us are familiar with the word sunscreen. No professional help is needed to use it. However, today we will discuss how important sunscreen is in our daily lives and sunscreen using tips.
Sunscreen creates a protective layer for the skin. It doesn’t just protect you from the sun’s rays; its job is to shield your skin from harmful ultraviolet (UV) rays. Additionally, it is effective when you spend a long time in front of screens—like working on a laptop or using a mobile phone. It even provides protection against the heat from a cooking stove. Sunscreen is especially important for those who have melasma or facial pigmentation issues.
SPF refers to the level of protection it provides against UV rays. SPF starts at 15. For people in our subcontinent, who generally have darker skin tones, an SPF of 15–30 is usually sufficient. Fair or very fair-skinned individuals who experience a burning sensation when exposed to sunlight should use SPF 45–90. If you want to select a standard SPF for our population, SPF 30–45 is a good choice. However, if you are exposed to intense sunlight, doing a lot of outdoor cooking, or similar activities, you should opt for SPF 45 or higher.
There are many types of sunscreens available. It is commonly mentioned that while both UVA and UVB rays affect the skin, UVA rays are more harmful. Therefore, when choosing a sunscreen, ensure it offers broad-spectrum protection, meaning it prevents damage from both UVA and UVB rays.
Now, let’s discuss formulations. Sunscreens come in two types of formulations: physical sunscreen and chemical sunscreen. In recent times, Korean cosmetic products, especially Korean sunscreens, have become very popular. When asked why they prefer Korean sunscreens, many young girls mention that these products don’t make their face oily or sweaty. However, the primary purpose of sunscreen is to provide protection.
Think of sunscreen like a sweater in winter. The sweater protects you from the cold weather, and while it keeps you warm, you might feel hot inside. Similarly, sunscreen protects your skin from the sun. If your sunscreen provides proper protection, some oiliness is normal; a lack of it is unusual.
Between physical and chemical sunscreens, physical sunscreens contain FDA-approved ingredients—typically 16–17 approved components—that make them highly effective. These sunscreens are especially recommended for individuals with conditions like melasma or similar skin issues. Physical sunscreens are less likely to cause an oily sensation, offer excellent protection, and are often used as medicinal products.
On the other hand, if you’re looking for an affordable sunscreen that provides decent protection without a heavy layer, chemical sunscreens can be a good choice. A high-quality chemical sunscreen should contain zinc oxide for effective protection.
Zinc oxide-based sunscreens are often more affordable. When you use them, they may create a white layer on your skin. The main difference between physical and chemical formulations lies here: physical sunscreens usually do not cause excessive sweating or oiliness, nor do they leave a white cast. On the other hand, chemical sunscreens can make your face appear white and may give a slightly sweaty sensation.
You can choose either type based on your preference and budget. Zinc oxide-based sunscreens are a good option if you’re looking for something cost-effective. Additionally, if you need prolonged sun exposure, using a sunscreen with zinc oxide is highly recommended.
Which sunscreen is suitable for you depends on your skin type. If you have oily skin, opt for a gel-based sunscreen. Previously, pharmaceutical or cosmetic companies primarily produced cream-based sunscreens. However, now they manufacture specialized sunscreens for kids and adults. For your body, especially if you’re traveling to sunny locations like Cox’s Bazar or Saint Martin, use body sunscreens.
Proper sunscreen using tips:
When using sunscreen, remember it doesn’t just protect your skin; it also forms a layer that shields you from UV damage. Extended sun exposure can accelerate the aging process by breaking down collagen in your skin. Therefore, using sunscreen with anti-aging benefits is essential. We have to follow sunscreen using tips.
Apply sunscreen 30–40 minutes before going outdoors or at least 15–20 minutes prior. Sunscreen layers don’t last long, especially chemical formulations and mineral-based sunscreens, which tend to wear off after some time. If your face becomes wet, wipe it with a tissue before reapplying.
If you’re exposed to the sun for extended periods (e.g., cooking, working outdoors, or during travel), reapplying sunscreen every 2 hours is essential to maintain its protective effects. Try to avoid direct sun exposure between 10 AM and 4 PM, especially if you have sensitive or burn-prone skin. While sunlight is good for vitamin D, prolonged exposure during this time can be harmful.
Lastly, if you’re near windows or traveling by bus for long hours, remember that UV rays can penetrate glass. Using sunscreen in such situations is equally important.
I hope this helps clarify how to choose and use sunscreen effectively. Often, we forget or fail to use it properly, which reduces its benefits.
