Estrogen and anti-androgens will reduce sebum production from sebaceous glands, thus reducing oil production and acne. It will positively affect your acne.
Androgen (T and DHT) increases sebum and likelihood of acne. This is the reason why it tends to afflict men more strongly.
As for scars, I don' t think it will make much a difference. In fact, estrogen increases skin pigmentation.

Physiological Changes Associated with the Menstrual Cycle
A Review"Androgens are well known to be the primary stimulator of sebum production in humans (17). Estrogens,
however, suppress sebum production at high concentrations. The sebum content of the skin is
therefore related to the menstrual cycle, with the lowest sebum level at the peak of the estrogen level
(18). The role of progesterone on sebum production is controversial and therefore inconclusive (19).
"The effects of estrogen on pigmentation were first implied by observed changes in pigmentation char- acteristic of pregnancy: patches of increased pigmentation on the face known as chloasma, as well as darkening of the skin of the areolae, the perineum, and the skin over the linea alba, which fade shortly after delivery (29). Application of estrogen-containing ointment to children results in hyperpigmentation, when applied to the genital area as well as the nipples and linea alba (33). Hyperpigmentation is also observed in some patients with use of oral contraceptives (20)"
