Why Is It Important To Apply Sunscreen Regularly?
Do you use sunscreen only during the hot summer months? If that is indeed the case, then it is time to rethink your skincare regimen. Sunscreen is not a product for seasonal use to beat the summer heat. The powerful ultraviolet rays can harm anyone’s skin, regardless of their gender, age or skin type during any season. Hence, dermatologists recommend regular use of sunscreen. Find out the benefits of sunscreen and how it can work wonders for your skin right here!
What Is A Sun Screen And How Does It Work?
Sunscreen or sun cream or suntan lotion can potentially absorb and reflect ultraviolet radiation. It is available in gel, foam, lotion or spray form. The skin can suffer from sun damage or sunburn due to two types of radiations – UVA and UVB. Using sunscreen regularly can help prevent premature signs of ageing such as wrinkles, moles and sagging skin which occur due to prolonged sun damage.
Organic chemical complexes in sunscreen help to absorb UV light. On the other hand, ingredients like titanium dioxide, zinc oxide, or a blend of both can reflect, scatter, and to an extent, absorb ultraviolet radiation. Newer molecules like Tinosorb M present in sunscreen lotion can reflect and scatter a fraction of light like inorganic particulates and absorb the radiations like organic ones.
What Does Sunscreen SPF Mean?
SPF or Sun Protection Factor is the number that you see printed on your sunscreen lotion. The higher the SPF number, the more protection you get from the UVB rays. SPF ranges from two and goes beyond 50. Know more about the different variants of sunscreen and make an informed choice while buying one:
- SPF 15: Blocks 93% of UVB radiation
- SPF 30: Blocks 97% of UVB radiation
- SPF 50: Blocks 98% of UVB radiation
It would be best if you use a sunscreen with a minimum of SPF 30.

- Myth: Sunscreen is a product for fair-skinned people only.
Fact: People with a darker skin tone should also stay sun-safe by using sunscreen as it is tough to identify the signs of sun damage. India has consistently reported two specific types of skin cancers to be the most prevalent as a result of exposure to these harmful ultraviolet rays, i.e. squamous cell carcinoma and basal cell carcinoma.
- Myth: There is no need to use sunscreen on cloudy days or if you stay indoors.
Fact: You should apply sunscreen every day irrespective of the weather outside as the clouds cannot impede the UV radiations. You should apply sunscreen even when at home because window-panes cannot obstruct UVA radiation.
- Myth: You will not get a sunburn and can skip the use of sunscreen if you are in the water.
Fact: Sunscreen washes off within an hour depending upon its water-resistance properties. Instead, more frequent application of sunscreen is advisable if you are swimming or sweating a lot.
- Myth: If you are using a sunscreen with a high SPF, it will last throughout the day.
Fact: A higher SPF indicates more sun protection rather than a prolonged one. It would be best if you reapplied sunscreen with higher SPF too.
