You might have heard from many to use sunscreen daily whether you go outside or staying inside. Even when you visit your skin specialist or dermatologists for consulting about sun burns or dark patches they firstly suggest you sunscreen along with some medication. So, if you are missing out this step, then incorporate it in your daily skin care regimen.
Excessive exposure to harmful ultraviolet rays from the sun has increased the risk of getting many skin problems. The immediate or direct exposure of the skin causes sunburn. The sunburns are the damaged cells and blood vessels and the repetitive damage starts with various skin sufferings like inflammation, dryness, pigmentation and uneven skin tone.
The biggest problem that most of us is facing is pre-mature aging. And don’t be shocked, if we say that ultraviolet exposure is one of the cruel reason behind it. By applying sunscreen daily will help you to delay aging. It not only helps you look youthful but also slows down the process of wrinkle formation.
Sunscreen evens the skin tone by preventing it from brown spots and skin discoloration. It also helps in preventing tanning. The ones who love sunbathing, you also allow harsh UVB rays to penetrate and damage your skin. So whenever you plan to have sunbath just make sure that you apply sunscreen as well.
Sunscreen also enhances the skin health while protecting all the vital proteins of the skin like collagen, keratin and elastin that keeps the skin soft, smooth, supple and healthy. The UV ray spectrum contains two types of rays - UVA and UVB. Both kinds of rays affect our skin based on how they are absorbed by the skin’s molecules (chromophores). UVB rays are responsible for sunburns and UVA rays cause tanning, carcinogenesis and ageing and even skin cancer. Sunscreens protect us from both the UV rays.
Do you know what SPF is?
You all search out for sunscreens on internet and what you see foremost is SPF. So what is this SPF?
It stands for Sun Protection Factor is a number that states how well a sunscreen will protect the skin from UV rays. This factor is calculated by dividing how much sun’s ultraviolet exposure is needed to cause the skin redness when sunscreen is used to how much exposure is needed to cause the redness with the sunscreen. (i.e.)
SPF = sunburn radiation dose with sunscreen / sunburn radiation dose without sunscreen
What is best for you?
Simply applying any sunscreen won’t help. It is important to choose the sunscreen which is best for you. As it determines how well you are protected. With uncountable options available, it is necessary to choose wisely while considering all the following points:
If you have a sensitive skin that gets sunburned in just 10 mins of exposure to the sun, applying a sunscreen with SPF 15 will protect you from skin redness and sunburns for about 150 mins. For best results, apply 2mg of sunscreen per square centimetre of your skin or 30 grams for full-body coverage, every two hrs.
- According to your skin type
If you have acne-prone skin, use only non-comedogenic formula sunscreen lotion. If you are allergic, avoid sunscreens that can contain preservatives, fragrances or alcohol. For the dry skin types, it is beneficial to use moisturizing sunscreens. However, some sunscreens are generic and can be used by anyone. So, if you want to use a single one for the entire family, it is better to opt for sunscreen that is best for all age groups and all skin types.
- Should be water proof
Always keep in mind that no sunscreen is waterproof. So, don’t fall for the products that say waterproof. If the label says that the sunscreen is water-resistant or sweat-resistant, look for how long it lasts. However, it is always advisable to apply sunscreen every 2 hrs especially when you are swimming.
