Blue light is emitted from electronic devices and is a major source of skin damage, leading to premature aging and increased risk of skin cancer. That’s why it’s important to choose the right blue light sunscreen for your skin. This ultimate guide to blue light sunscreen will provide you with all the information you need to make an informed decision. You’ll learn about the different types of blue light sunscreen, the active ingredients to look for, and the best ways to apply it. With this guide, you’ll be able to find the perfect blue light sunscreen for your skin and enjoy the benefits of protection from harmful blue light.
What is blue light?
Blue light is part of the visible light spectrum that reaches the earth. This type of light is produced by the sun and by artificial light, such as from your computer screen. Blue light is considered harmful because it’s higher in energy (i.e. it has more power) and more effective at penetrating our skin and causing damage compared to other light wavelengths. When UV rays (from the sun and artificial light) reach the skin, they’re absorbed by certain molecules that create reactive oxygen species (or ROS). These ROS can damage the DNA in our cells, leading to skin aging and increasing the risk of skin cancer. The molecules that absorb UV rays and create ROS are called photosensitizers. Blue light is particularly effective at penetrating the skin and triggering these photosensitizers, resulting in greater ROS production and damage to the skin.
The dangers of blue light
Blue light is harmful for the skin in many ways. Exposure to blue light leads to premature aging of the skin, and it can also cause hyperpigmentation and wrinkles. It causes these signs of aging because it triggers an inflammatory process in the skin that leads to an increase in ROS and inflammation. Blue light can also lead to DNA damage and increase the risk of skin cancer. Research has shown that blue light has the potential to induce oxidative damage in both the skin and the corneal epithelium (the cells on the surface of the eye). This can lead to cataracts and other degenerative eye conditions. Blue light can also disrupt the circadian rhythm, increasing your risk of sleep disorders, mood disorders, and other health issues.
Types of blue light sunscreen
There are two main types of blue light sunscreen: chemical and physical. Both types of blue light sunscreen use active ingredients to block the harmful blue light from reaching your skin and causing damage. Chemical blue light sunscreen uses molecules to block blue light, while physical blue light sunscreen uses minerals to reflect blue light away from the skin. – Chemical blue light sunscreen: Chemical blue light sunscreen uses molecules like avobenzone and octocrylene to absorb blue light and prevent it from reaching your skin. Chemical blue light sunscreen is generally easier to apply and less messy than physical blue light sunscreen. However, chemical blue light sunscreen offers less protection against blue light than physical blue light sunscreen. – Physical blue light sunscreen: Physical blue light sunscreen uses minerals like zinc oxide and titanium dioxide to reflect blue light away from the skin. This type of blue light sunscreen is usually thicker and more difficult to apply than chemical blue light sunscreen. However, it offers better protection against blue light than chemical blue light sunscreen.
Active ingredients to look for
There are many different active ingredients used in blue light sunscreen, and each provides a different level of protection from blue light. Choosing a blue light sunscreen with a high-quality active ingredient can help reduce the risk of skin damage and protect your skin from premature aging. Avobenzone: This is a high-quality blue light sunscreen that can be found in both chemical and physical blue light sunscreen. Avobenzone is the most effective blue light sunscreen ingredient and can reduce the amount of blue light reaching the skin by up to 90%. Octocrylene: Octocrylene is another high-quality blue light sunscreen that can be found in both chemical and physical blue light sunscreen. It’s highly effective at blocking blue light, and research has shown that it can reduce the amount of blue light reaching the skin by up to 99%. Mexoryl SX: Mexoryl SX is a high-quality blue light sunscreen that can be found in both chemical and physical blue light sunscreen. It’s less effective than avobenzone and octocrylene, but it’s more stable in sunlight. That means it’s less likely to break down when exposed to UV rays.
Best ways to apply it
You should apply blue light sunscreen every time you go outside, even if it’s overcast. The harmful blue light from the sun can still penetrate through clouds and haze, and it can also be reflected off surfaces like water, sand, pavement, and concrete. You should also apply blue light sunscreen when you’re at home, because most electronic devices emit blue light in varying degrees. When you’re applying blue light sunscreen, it’s important to use enough. Most experts recommend using about one teaspoon of sunscreen for each limb. That’s about two tablespoons for your face and neck, two tablespoons for your torso, two tablespoons for each leg, and one tablespoon for each arm. You should also apply blue light sunscreen 30 minutes before you go outside and re-apply every two hours, or after sweating, swimming, or doing anything that might cause your skin to rub against clothing.
How to choose the right sunscreen for your skin
Before choosing a blue light sunscreen, you’ll first need to determine what type of skin you have. There are three basic skin types: dry, oily, and normal. You can also determine your skin type by looking at the condition of your skin. People with dry skin have scaly, rough patches, whereas people with oily skin have an oily shine on their skin. Most people have normal skin, which has a combination of these two qualities. Once you know your skin type, you can select a blue light sunscreen based on the ingredients it contains. For example, if you have dry skin, you might want to select a blue light sunscreen with hygrocentrogene or sodium hyaluronate because they have moisturizing properties. Similarly, if you have oily skin, you can select a blue light sunscreen without those ingredients.
Benefits of using blue light sunscreen
Blue light sunscreen is one of the best ways to protect your skin against blue light, and it comes with many benefits. First, it will protect your skin from premature aging, which is one of the main signs of blue light damage. Blue light can also cause hyperpigmentation and wrinkles, so blue light sunscreen can also help reduce these issues. Blue light can also lead to DNA damage and increase your risk of skin cancer, so wearing blue light sunscreen can help reduce those risks. Finally, blue light can also disrupt your circadian rhythm, which can increase your risk of sleep disorders, mood disorders, and other health issues. Blue light sunscreen can help reduce these issues by blocking the harmful blue light.
Common sunscreen mistakes to avoid
The best way to ensure you’re using blue light sunscreen correctly is to avoid making common mistakes. One mistake people often make is using the wrong sunscreen. You should always wear blue light sunscreen when you go outside, even if the sun isn’t visible. Even if the sun isn’t out, harmful blue light can still reach your skin and cause damage. Another common mistake is not applying enough sunscreen. You should apply about two tablespoons of sunscreen for your face and neck and two tablespoons for your chest, back, legs, and each arm. You should also wear sunscreen when you’re indoors and near electronic devices (especially computers) that emit blue light, even if you’re wearing sunglasses. It’s also important to re-apply blue light sunscreen every two hours, or after sweating, swimming, or anything that can cause your skin to rub against clothing.
