The size of the zinc oxide market is expected to touch the USD 5.7 billion mark by 2024. A large part of the aggregate demand for this solution comes from the cosmetic industry. The mineral, in specific, is widely used in sunscreens and select type of lotions.
There have been times when the safety of using zinc oxide in sunscreens has come under scrutiny. However, at large, dermatologists across the world agree in unison that it’s safe and healthy. Several studies have been done on this that ended up underpinning the same conclusion.
Zinc oxide acts as a filter that protects against UVA and UVB rays. This is the biggest reason why it’s used as an ingredient in sunscreens. Moreover, it works pretty quickly. Since it’s a physical blocker, after application, you don’t have to wait before hitting outdoors. You can apply and go out immediately. Zinc oxide does not cause allergic reactions; when it happens, it happens only in very rare cases. It’s also suitable for every kind of skin, including the over-sensitive skin. (Although you might still want to talk to your dermatologist before applying any kind of cream on the skin, irrespective of whether it includes zinc oxide or not.)
However, all said, there are some caveats when discussing the safety of sunscreens with this mineral. Although, again, it’s quite safe, a lot really depends on the manufacturer of the sunscreen. Before and during the use of the mineral as an ingredient in the sunscreen, the manufacturers must properly break down the active substances into microscopic particles to make the cream transparent. Else, zinc oxide will become very white when applied to the skin, giving the person a ghost-like appearance.
Also, the manufacturers must use coated zinc oxide to make sure the free radicals – which is formed when the mineral meets sunlight – don’t damage the cells and DNA due to lack of antioxidants. Of course, they must also follow the industry standards and safety guidelines throughout the manufacturing process. One of the big parts of their responsibilities is purchasing the stock from good zinc oxide manufacturers in Kolkata who offers superior quality solution of a suitable grade.
At large, as approved by the FDA and even recommended by dermatologists, zinc oxide is very safe for skin. If you’re a manufacturer of cosmetic products, feel free to use this mineral filter in your sunscreens. (Do check your local laws and guidelines though!) And if you’re a consumer, invest in good brands and don’t freak out the next time you see “zinc oxide” on the label of any cosmetic product; it’s safe!
