Applying sunscreen is the most commonly used sun protection methods across the globe. Effective sun protection is instrumental in reducing the risk of skin diseases which are related to overexposure to sunlight.


Why is sun protection important?

A few types of UV radiations produced by the sun, especially UVA and UVB radiations can cause sun spots, basal cell carcinoma, squamous cell carcinoma skin cancers and melanoma, ageing effects such as skin dryness, pigmentation and loss of elasticity of the skin.


There are number of methods of sun protection such as proper clothing, broad hats, wetsuits but sunscreens are the most effective method of sun protection and the most widely accepted as well.


How do sunscreens work?


Sunscreens can be in the form of creams, lotions, mists, sprays or gels. When applied to the skin they help in reducing the effect of ultraviolet radiation to the skin by reflecting or absorbing.


Reflectant sunscreens contain zinc oxide and titanium dioxide and give a milky-white appearance to the skin after application.

Absorbent sunscreens contain a mixture of the following synthetic and are usually invisible when applied to the skin.


The results of a sunscreen depend on method of use. A dermatologist in Chandigarh Panchkula instructs that for best results, adequate amounts of sunscreen should be applied about 20 minutes before going out into the sun, and at least every 2 hours till outdoors.


What is SPF?


Sun protection Factor (SPF) is the amount of UVB radiation that is safe for the skin with sunscreen compared with no sunscreen. So, an SPF 50+ sunscreen allows 50 times protection from sun that without sunscreen. Since, SPF only indicates protection against UVB, a skin doctor in Chandigarh advises patients to choose a sunscreen labeled “broad-spectrum” which protects against both UVA and UVB.


Sunscreen Side-effects


Despite being subjected to extensive testing, some synthetic chemicals in sunscreen can occasionally cause mild irritation, or acne like eruptions.

There is limited citing of long-term problem related to regular use of sunscreen. However, the best skin specialist in Chandigarh advises to visit the nearest dermatologist in case of doubt and choose covered clothing to protect against UV radiations.


Vitamin D & Sunscreen


It is true in theory that sunscreen also limits the absorption of Vitamin D. However, if you have a history of skin cancer or sensitivity to sun, or reside in areas close to the equator, it is best advised to speak with your primary care giver on vitamin D deficiency due to regular use of sunscreen.

No sunscreen will block 100% of UV radiation – there is always some UV that reaches the skin even when the sunscreen has been applied correctly.




The best dermatologist in Panchkula enlightens that one cannot fully rely on sunscreens and advises on avoiding exposure to sunlight at peak UV times especially during the middle of the day, wearing protective garments and seeking shade when outdoors.
