Striae distensae - 萎縮紋https://en.wikipedia.org/wiki/Stretch_marks
妊娠紋 (Striae distensae) 是皮膚上一種顏色不正的疤痕。隨著時間的推移,它們可能會減少,但不會完全消失。妊娠紋是由身體快速生長期間(例如青春期或懷孕期間)真皮撕裂引起的,妊娠紋通常在懷孕最後三個月形成。這些妊娠紋通常出現在腹部,也常見於胸部、大腿、髖部、下背部和臀部。妊娠紋也可能受到與青春期、懷孕或荷爾蒙替代療法相關的荷爾蒙變化的影響。沒有證據顯示懷孕期間使用的乳霜可以預防妊娠紋。

治療
當你體重增加太快時就會發生這種情況。在這種情況下,逐漸減重有助於防止妊娠紋惡化。

妊娠紋是一種常見的皮膚病,多見於 5 至 50 歲的女性。它們會引起美容問題和情緒困擾,尤其是對於女性和某些注重外表的職業。治療方法通常包括維他命A酸 (tretinoin)、乙醇酸 (glycolic acid) 和抗壞血酸 (ascorbic acid) 等乳膏,以及二氧化碳 (carbon dioxide)、Er:YAG、二極體 (diode)、Q‑切換 Nd:YAG、脈衝染料雷射 (pulse dye) 和准分子雷射 (excimer) 等各種雷射。其他設備如射頻 (radiofrequency)、光療 (phototherapy) 以及血小板富血漿 (platelet rich plasma)、化學換膚 (chemical peeling)、微晶磨皮 (microdermabrasion)、針刺 (needling)、二氧化碳療法 (carboxytherapy) 和電針 (galvanopuncture) 亦有使用,效果不一。
Striae distansae (SD) or stretch marks are very common, asymptomatic, skin condition frequently seen among females between 5 to 50 years of ages. It often causes cosmetic morbidity and psychological distress, particularly in women and in certain professions where physical appearances have significant importance. Commonly cited treatments include topical treatments like tretinoin, glycolic acid, ascorbic acid and various lasers including (like) carbon dioxide, Er:YAG, diode, Q-switched Nd:YAG, pulse dye and excimer laser. Other devices like radiofrequency, phototherapy and therapies like platelet rich plasma, chemical peeling, microdermabrasion, needling, carboxytherapy and galvanopuncture have also been used with variable success.

Topical treatment modalities are mainly used as an adjunctive treatment. Ablative lasers and non-ablative lasers are the most popular, among which picosecond has been tried in striae distensae treatment in the last two years. Combined treatment modalities are currently a hot spot for SD treatment, and microneedle radiofrequency and fractional CO2 laser combined with other treatments are the most common. Microneedle radiofrequency is the most commonly used and achieved therapeutic effect among the combined treatment modalities.
