Detailed answer

Hormone levels play a role in scar appearance due to their impact on collagen synthesis and remodeling. Higher levels of estrogen, for example, promote collagen production, leading to improved scar healing and reduced appearance. Conversely, lower levels of estrogen can hinder collagen production and delay scar healing, resulting in more prominent scars. Additionally, the androgen hormone dihydrotestosterone (DHT) can contribute to the formation of hypertrophic scars and keloids by stimulating fibroblast activity. Therefore, hormonal imbalances or fluctuations can affect scar formation, healing, and overall appearance.
