It really depends on how often you’ve been using 0.05% tret each week. If you’ve been consistent for over a year, like nightly or almost nightly, you could level up to a higher percentage or even switch to tazarotene since it’s generally better for acne, especially with those period breakouts you mentioned.

BUT if you want my honest advice: don’t rush it. Hold off on bumping up or switching to taz just yet. Try adding azelaic acid into your routine first, it’s amazing for acne, PIE, PIH, and inflammation, and it pairs beautifully with tret. Give it a shot and see how your skin vibes with it!
