What is SPF in Sunscreen? – Understanding SPF 30, SPF 50, and SPF 70

Thursday, March 21, 2024

As global temperatures rise and the threat of global warming is more real, the sun has become harsher around the world. Apart from the effect the sun rays have on the polar ice caps, the effect they have on your skin is also very real. It is important to remember that our skin is very delicate and is always exposed to the outside environment. Exposure to harsh sun rays for longer periods of time can also lead to skin cancer and other complications. 

Therefore, it becomes very necessary to wear sunscreen and other sun protection items if you are going out. Even when you are indoors, you should use sunscreen. Sunscreens come with SPF benefits, and they should be used not only on your face but also on your body. In this article, you will learn about the sun protection factor in sunscreens and what the different numbers mean. 

Which is better, SPF 30 or 50? 

The SPF in many generic creams can be as low as 15 or 24. SPF 15 blocks out around 93 per cent of the UVB sunlight. However, this is not enough protection when you are going to be out for a longer time or constantly travelling. The higher up you go on the SPF scale, the better. In this harsh climate, you need at least SPF 30 for your face and body. SPF 30 sunscreen can filter out at least 97 per cent of the harsh sun rays. Today, the SPF number can also go up to 100, and an SPF of 100 is used to block out UV rays from your skin. 

An SPF 50 sunscreen protects your skin from 98 percent sun rays, and this is a good amount if you are not going to be out for long. You also need to reapply your sunscreen every 4 hours or so. However, we have also created long-lasting sunscreens with natural ingredients that not only protect your skin but nourish it. The higher you go on the SPF scale, the fewer chances there are to reduce the possibility of sunburn. A sunscreen SPF 50 like Sun Shield Sandalwood 50+Spf lotion from our brand can protect your face from sunburns and redness. 

Why go higher than the SPF 50 mark? 

However, if you want to protect your skin completely from sunburns and you have sun-sensitive skin, then you should choose sunscreen with SPF 70. SPF 70 blocks 99 per cent of the sunlight from your skin, so there are almost zero chances of sunburns and sun damage. If you are someone who goes out in the sun and works outside for the whole day, you should choose a sunscreen that has SPF 70 or 100. 

As the ozone layer becomes thinner and we are facing higher temperatures, it is important to choose skin-safe sunscreens with high SPF ratings. These days, you can also find sunscreens that are multi-purpose and act as moisturisers too. A multi-purpose sunscreen protects your skin and also moisturises it. Thus, a sunscreen like Sun Shield Aloe Vera 75+Spf Sunscreen Lotion is lightweight, moisturises and soothes, too. 

This product from our sun protection collection also simplifies your daycare routine. If the question is which SPF sunscreen is better, then anything above 50 and around SPF 70 is great for your skin. As we create higher SPF sunscreens, the debate is no longer limited to SPF 30 vs 50

How to choose a good sunscreen?

You have to be very careful about what you put on your face. Of course, you need sunscreen, but a lot of sunscreen formulations are made for specific skin types and do not agree with every person. Therefore, you have to check for different sunscreen formulas and find the best one that suits you. Once you have established which sunscreen is best for your face, you need to use it religiously on your face every day before stepping out of the house. Here’s how you can find the best sunscreen for your face. 

Skin type

Your skin type determines the type of sunscreen formula you use. If you have oily or combination-type skin, then greasy or creamy sunscreens are not the best solution. If you have oily skin, it is best to choose a gel sunscreen or mattifying sunscreen. Sun Shield Bio Sunflower Matte Ultra Soothing Body Lotion with SPF 50 is a good choice for an oily skin person. The Aloe Vera & Raspberry SPF 50 Hydra Gel Indian Sunscreen is great for all Indian men and women. The gel formula also acts as a moisturiser for your skin during the summer. 

White cast 

A lot of sunscreens have a formula that is either too oily or leaves a white cast. A white cast might come from the ingredients used in the sunscreen. However, you have to make sure that the sunscreen you choose does not leave a white cast. The white cast can look really bad when you sweat and can also make you look like a ghost. You should check the finish of the sunscreen at the store and read the reviews before going for a sunscreen. Bxl Cellular Protection Cream SPF 50 is an all-in-one cream that protects and nourishes the skin. It does not leave a white cast and blends in easily. 

Pilling 

Sometimes, when the sunscreen is too thick in consistency and does not go well with your skin, it will start to pill. Choose a sunscreen that goes well with your skin and seamlessly blends with your skincare routine. The sunscreen should also not react with any makeup product you use on top of it. A lightweight cream sunscreen like Bxl Cellular Protection Cream SPF 40 UVA/UVB Sunscreen is a good one to choose from for multiple benefits.

Conclusion 

A good sunscreen is an absolute necessity for both men and women. Using sunscreen not only keeps your skin young but also protects you from skin disorders. At Biotique, you can buy sunscreens that come in different consistencies and have a wide range of SPF values.
