Hydrogen peroxide, also referred to as Eskata was approved in December 2017 by FDA in US considering the clinical trials that were done. Eskata is used only as a topical solution and has 40% concentration of hydrogen peroxide. The concentration is considered really high, which is why it is recommended that you visit your doctor to have it applied to the age spots on your skin. The reason it is considered a really effective treatment is not only because it is one of the fastest ways to get rid of age spots, but it also helps remove them without damaging the healthy skin around your age spots.
Although hydrogen peroxide is fairly easy to use. All you need to do is simply apply it to the area around 1 to 3 times each day. However there is a really big concern here - the concentration of hydrogen peroxide.
This is where things can get a bit tricky. Most hydrogen peroxide bottles that you'll find online or OTC have a very low amount of concentration of hydrogen peroxide. It is as low as 1% to 3% and they're not evaluated by FDA in terms of the effectiveness.
Depending on the size and number of age spots that you have, the low concentration of hydrogen peroxide might not end up working for you. Which is why Eskata (approved by FDA) has around 40% hydrogen peroxide compared to 3% that you'll buy for online.
If you visit your doctor to have the age spots treated, they'll most likely use the 40% and there's way higher chances of it working for you. However, removing age spots might be considered a cosmetic procedure by your insurance company and you may need to pay the full price out of your pocket.
Prevention has always been known as better than cure. You may have existing age spots but you can prevent the new ones by avoiding excessive exposure to sun or by using a sunscreen. Age spots are generally harmless and if they don't bother you, simply embrace them. However if you're suspicious about the age spots being cancerous, you should get them evaluated by your doctor ASAP.
