I know tan lines on your face from wearing sunglasses can be particularly frustrating, since they are prominent and can't be covered up with clothing. Thankfully, there are simple home remedies that can help speed up skin cell renewal to fade tan lines, and easy ways to cover up and disguise the lines as well.
Cut a lemon in half and rub the inside on darker skin for one to two minutes. Then rinse your face. The acidity in lemon can bleach out dark skin and help fade tan lines. Do a patch test with the lemon juice first on an inconspicuous part of your body, to be sure that your skin does not have any reactions to the acidity.
Use an exfoliating brush or sponge in the shower, focusing on the tan line itself. Be gentle with the skin on your face, as too much rubbing can cause irritation and redness. While it won't get rid of tan lines altogether, it will speed up your skin's cell renewal process, slowly fading the tan.
Apply a facial lotion with alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), which shed dead skin cells and fade the tan line. Be sure to sure a moisturizing lotion specifically labeled for the face, since body lotions can have higher concentrations of the acids and might damage fragile facial skin.
Well, it seems that you are not satisfied with the tan lines on your skin, so I also find them very bad. Since the tan lines are resulted from long time of exposure to the sunshine, which looks really bad. Anyway, if you want to change the tan lines on your skin, you should wear less glasses, maybe sometimes, you could wear contact lenses in outdoor activities. And get some sunscreen cream to help.
Well, yes, it is annoying to have tan lines after you wearing too many glasses. So you can just try some ways to cure it. For example, you can use a sunscreen with an SPF (sun protection factor) of at least 15. Also, sunscreen can be effective too. So you can just use a sunscreen that contains zinc oxide or titanium. In my opinion, if you use them in a long term, it can relieve the symptom. By the way, using an exfoliating lotion can also help get rid of a tan more quickly. Anyway, just have a try.
According to my knowledge, there 3 aspects to get rid of tan. First of all, cover skin up. Secondly, try to avoid 10:00am to 4:00pm sunshine. I don't like go out during that time. It is too hot. I can barely open my eyes. Thirdly, wearing suncrean is necessary. If you are staying at home, you need sunscrean with SPF 15 at least. If you plan to go out, you need sunscrean with SPF above 30. Yet for the tan lines for wearing too much glasses, I suggest you to choose contact lenses instead of glasses. We all know that wearing too much glasses leaves marks in faces, which look ugly. I suggest you take the 3 aspects of action as I said above. And meanwhile, wearing contact lenses instead of glasses. Contact lenses are very safe to wear and also very convenient. I think contact lenses give me a better and clearer vision too, without worry that there would be some tan lines or marks on my face.
