Dear Hi, Welcome to Healthcaremagic!
Size of breasts is like size of penis: no exercises or medications will increase the size. Activity of suckling & fondling during sex releases oxytocin
hormone which causes some increase in breasts' size. During pregnancy
, hormonal changes have same effects & increase in size post pregnancy is maintained. Size of breasts has NO effect on sex or lactation
. Also plastic surgery
is safe, but not your preference. As far as acne is concerned, treatment will depend on extent: You may start Adapalene
0.1% (Adaferin) gel applied at night. Clean your face with a good soap 2-3 times a day. Good luck.
