Need help with Tret 0.05%

I hv been using 0.025% since a month nd a half nd at first i did get purging but after 2-3 days it went aways nd hv been like normal since then, no peeling or burning etc. I'm using it on alternate nights just to be safe.

On many days i hv also applied quite more than just the pea size nd it didn't affect me. So i was thinking if i should just to 0.05% after 6 months or should i just keep using it thinking "if its not broken then it doesn't needs to be fixed".

Plz do help me. I'm quite a rookie with tret as u can understand. Thanks in advance
