甚麼是孕斑？

孕斑又稱黃褐斑，通常會在懷孕第4個月至第6個月出現。這些棕色的斑點深淺不一，通常會出現在前額、臉頰和上唇。它們邊緣分明，形狀均勻，通常對稱地分佈。孕斑的出現因人而異：深色頭髮的女性通常比金髮女性更嚴重。孕斑的發展週期取決於肌膚的光感類型。

孕斑的成因是甚麼？

懷孕時，人體會產生更多雌激素，從而促進黑色素的產生。暴露在陽光下時，肌膚會發生這種反應產生色素的化學反應，導致暗斑出現。日曬可能會嚴重增加出現孕斑的風險。暴露在陽光下的時間會影響黑色素的產量，並很有可能會導致黃褐斑。此外，孕斑還受到遺傳因素和生活習慣的影響，例如臉部過度去角質會導致情況加劇。

如何防止孕斑形成？

為避免出現黃褐斑，懷孕期間應盡量減少陽光照射臉部。無論是在市區還是海邊，都要全副武裝！ 即使只是短時間曬太陽，也可能會功虧一簣。  當然，您不必在整個懷孕期都留在漆黑的房間裏，只需遵循一些基本原則即可：出門時佩戴帽子，妥善塗抹高防曬系數（SPF 50）的產品，每隔兩小時補塗一次，並使用抗斑面霜。

產後孕斑

您無需在懷孕期四處探尋解決方法。一般來說，孕斑會在產後6個月內消失。如果這些令人討厭的斑點無法消退，亦可諮詢皮膚科醫生。他們會根據您的肌膚類型，推薦合適和有效的面霜、去角質產品和精華。
