Your areolas might darken slightly, or your nipples may feel more prominent—even when it’s not cold. This is hormonal drama at its finest. Changes in pigmentation and texture are classic side effects of estrogen pulsing through your twenties.
You might also notice little bumps (Montgomery glands) becoming more visible on the areola. They’re not acne—they’re oil glands that step up their game to keep the growing tissue lubricated. Side note: your nipples are literally preparing for potential future breastfeeding, even if you have no plans for that.
