Anecdotally (and we've discussed this here on s.com before) it seems that estrogen can cause oily skin as well as DHT. Estrogen can technically "treat" acne in some cases, but even though the skin has functional estrogen receptors (and can get acne from too much estrogen in some cases), the treatment of acne with estrogen is because adding estrogen will lower androgen levels, not necessarily a direct result, per se.
Remember, some steroids don't convert to DHT at all, and still give us acne, and others don't aromatize, and still give us acne; still others do neither and yet give people acne anyway (Tren).
Many factors are important in acne, and not everything is known yet:

Acne vulgaris is the most common skin condition observed in the medical community. Although we know that hormones are important in the development of acne, many questions remain unanswered regarding the mechanisms by which hormones exert their effects.
Androgens such as dihydrotestosterone (DHT) and testosterone, the adrenal precursor dehydroepiandrosterone sulfate (DHEAS),
estrogens such as estradiol, and other hormones, including growth hormone and insulin-like growth factors (IGFs), may be important in acne. It is not known whether these hormones are taken up from the serum by the sebaceous gland, whether they are produced locally within the gland, or whether a combination of these processes is involved.
Finally, the cellular and molecular mechanisms by which these hormones exert their influence on the sebaceous gland have not been fully elucidated. Hormonal therapy is an option in women with acne not responding to conventional treatment or with signs of endocrine abnormalities.
