A sunburn is a form of radiation burn that affects living tissue, such as skin. It is the result of overexposure to ultraviolet (UV) radiation, commonly from the sun causing red, painful, itchy skin.
Sunlight that reaches us consists of two types of harmful rays: Longwave Ultra Violet rays (UVA) and Shortwave Ultra Violet rays (UVB). UVA penetrates deep into the dermis, the skin’s thickest layer, While UVB rays usually burn the superficial layers of our skin.
Unprotected exposure to UVA rays can lead to premature skin aging and wrinkling.
Unprotected exposure to UVB rays can lead to skin reddening and sunburn.
The ingredients in the sunscreen are such that they reflect or scatter the sunlight away from the skin. Also, there are few sunscreens with such ingredients that can absorb UV rays to avoid damage to the skin.
SPF stands for ‘Sun Protection Factor.’ It is the UVB protection offered by sunscreen to the skin. The number associated with the SPF is the multiple times our skin shall be protected longer from burning than we would be without sunscreen.
PA stands for ‘Protection Against’ UVA rays. It is the Protection grade that tells the amount of protection offered by sunscreen from UVA rays.
‘+’ sign stands for the level of protection offered by the sunscreen. More ‘+’ signs signify the higher level of protection offered by sunscreen.
Infrared radiations are the harmful invisible electromagnetic radiations emitted by the sun which break down collagen and accelerates skin aging.
To get the most from our sunscreen, Apply liberally 30 minutes before sun exposure. Reply the same after 2 hours.
Physical sunscreens protect our skin by reflecting the UV rays while chemical sunscreens protect by absorbing the UV rays.
Nanotechnology-based sunscreens form true gel based and easily spreadable sunscreens which provide prolonged protection without skin whitening effects. These are non-irritant to sensitive skin and provide all day long refreshing feeling.
Premature aging of skin caused by prolonged sun exposure, specifically UVA & UVB rays.
Antioxidants are substances that may prevent or delay some types of cell damage. They neutralize free radical damage thus protects the skin from fine lines, wrinkles, and photoaging.
80% of UV rays penetrate the cloud cover; thus it is always advised to put sunscreen on a cloudy day.
