Why does testosterone cause acne, and does it mean estrogen is too high?

Testosterone can increase skin oil production and contribute to clogged pores and inflammatory acne. That is a direct reason for breakouts during androgen exposure; it does not require elevated estrogen. The American Academy of Dermatology recognizes acne as a common issue during testosterone therapy, although its guidance is not a trial of bodybuilding steroid combinations.[1]

The timing and pattern matter. Deep painful lesions, scarring, and widespread back or chest acne need a different approach from a few superficial spots. Harsh scrubbing and picking can worsen irritation and scars. A dermatologist can confirm the diagnosis, since other follicular conditions can resemble acne.[1]

Acne treatment can often be coordinated with medically necessary hormone treatment. The assessment should also consider whether the androgen exposure is appropriate. Adding an estrogen blocker solely because acne appeared is not a diagnosis-based strategy. Treat the skin condition and its contributors instead of assuming that every visible side effect points to the same hormone.[1]
