Exposure to the sun can damage the skin permanently. Use of Sunscreen Formulation can give you protection against any damage. The harm might be short-term or long-term depending on the type of skin and the period of exposure. The short-term damage manifests as erythema or redness of the skin which people call sunburn. Melanocytes get activated leading to increased production of melanin. This darkens the skin causing a tan to appear.
Making the Sunscreen Formulation The Sunscreen Formulation involves the mixing of an oil phase and a water phase to form an emulsion. Absorbers and UV filters get mixed in as dry powder. The water phase contains emulsifiers and stabilizers. Powder ingredients such as stearic acid and cetyl alcohol get dispersed into the oil phase. This can give you enough long-term protection as well as a short-term one. Damage caused by UV rays When we talk of long-term damage we refer to skin elasticity lost permanently. It might lead to the development of skin cancer. The actual damage depends on how long one remains exposed and the intensity of the sunlight at that time. Other factors that determine the level of damage are age, gender, color, and immune status. So, one has to consider these factors while making the sunscreen product formulation. Protection Using Sunscreens The use of material to get protection from the harmful effects of the sun’s rays has been around for a long time. In the sun’s rays, we have gamma rays, cosmic rays, radio waves, microwaves, UV rays, and X-rays. The main focus of the sunscreen product formulation is to get protection from the UV rays that cause the most damage. We can use organic and inorganic substances to get this protection. Organic sunscreens include oxybenzone, sulisobenzone, and bisoctrizole. Inorganic sunscreens use zinc oxide and titanium dioxide. They give good protection across the entire spectrum of UV rays.
