Damage is not already done. You can still change it. I used creams for four years & have been waxing since 6 years now. No doubt there is a difference. I can easily go without any clean up for 1 1/2 months or in some cases even 3 months. Only eye brows & upper lips need attention every 2 weeks.
If you did it yourself. There are many reasons why it didn't suit you. You probably pulled the strip wrong way or rubbed it too hard on your skin. You probably didn't stretch your skin enough. Which obviously is not easy if you are doing it yourself. Second there are different kinds of waxes for different body parts & skin sensitivity. Maybe try something else.
Also if you are not comfortable exposing yourself. Wear a tank top or a short sleeved shirt. You are covered & you can get the job done.
