Pregnancy is one of the most transformative chapters of a woman's life, and your skin deserves the same level of care and attention as every other part of this journey. Yet for many expectant mothers, navigating skincare becomes a source of anxiety rather than self-care.

At REPIC Clinic, located in the heart of Gangnam-gu, Seoul, our board-certified dermatologists have helped hundreds of pregnant patients maintain radiant, healthy skin, without compromising safety. Whether you're dealing with melasma, hormonal acne, or early stretch marks, expert guidance makes all the difference.

In this complete guide, we break down exactly which treatments are safe, which to avoid, and how to build a pregnancy skincare routine trusted by Seoul's most discerning mothers.

Why Does Skin Change During Pregnancy?

Most skin changes during pregnancy are caused by hormonal fluctuations,  particularly estrogen and progesterone, which directly affect the skin. At REPIC Clinic, the most common concerns we see among pregnant patients in Gangnam and Seoul include:

• Acne: Increased hormone levels boost sebum production, clog pores, and cause breakouts.

• Melasma (Pregnancy Mask): Higher melanin production creates brown patches on the face.

• Stretch Marks: Rapid skin expansion on the abdomen, thighs, and buttocks causes red or purple streaks that gradually turn white.

Treatments Pregnant Women Should Avoid

1. Monopolar Radiofrequency (RF) Lasers
   
   

   

   Devices like Thermage, Oligio, Ultherapy, or Density penetrate deep tissues. Unlike bipolar RF, monopolar RF passes current through the body, which may affect the fetus.

   
   

2. Procedures Requiring Local Anesthesia
   
   

   

   Local anesthetics like lidocaine and prilocaine are generally safe (FDA Pregnancy Category B) but may be risky if absorbed into arteries, potentially causing seizures, arrhythmia, or shock.

   
   

   Pregnancy Category	Description
   A	No risk in controlled human studies: Adequate and well-controlled human studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).
   B	No risk in other studies: Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women, or animal studies have shown adverse effects, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.
   C	Risk not ruled out: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
   D	Positive evidence of risk: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
   X	Contraindicated in pregnancy: Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.
   N	The FDA has not yet classified the drug into a specified pregnancy category.

   
   

3. Injectables
   
   

   

   Procedures like Botox, fillers, anti-inflammatory injections, or skin boosters lack sufficient safety data during pregnancy. Steroid-containing injections (e.g., triamcinolone) can impact fetal growth.

   
   

4. Retinoid Medications and Products
   
   

   

   Prescription acne medications like isotretinoin (Accutane) and minocycline, as well as retinoid creams or cosmetics, can cause fetal malformations. Avoid chemical peels as well.
