Why Scars Can Form After Skin Polishing: Causes, Prevention & Treatment

Skin polishing, also referred to as microdermabrasion, is a cosmetic treatment designed to exfoliate dead skin cells, improve texture, and promote a healthy glow. While this procedure is generally safe, some people may experience scarring as an unwanted side effect.

What Is Skin Polishing?

Skin polishing involves mechanical exfoliation using crystals, diamond-tipped tools, or chemical agents to remove the outer layer of dead skin. It rejuvenates the skin and improves its appearance — but if performed incorrectly, it may cause skin damage.

Why Can Skin Polishing Cause Scars?

• Excessive Pressure or Aggressive Technique: Too much force can create micro-injuries, which may scar if they don’t heal properly.
• Pre-Existing Skin Conditions: Conditions like acne, eczema, or rosacea can worsen and increase the risk of post-inflammatory scarring.
• Infection After Treatment: Bacteria entering broken skin can lead to infection and delayed healing.
• Inappropriate Frequency: Not allowing enough recovery time between treatments can damage the skin barrier.
• Sun Exposure Without Protection: UV rays can cause sunburn or hyperpigmentation on freshly polished skin.

How to Prevent Scars After Skin Polishing

• Choose a certified and experienced professional.
• Discuss your skin history before treatment.
• Allow proper intervals (2–4 weeks) between sessions.
• Use gentle, healing skincare post-treatment.
• Apply SPF 50 daily to protect vulnerable skin.
• Never pick or scratch healing skin.

What to Do If You Develop Scars

• Apply silicone-based scar gels to reduce appearance.
• Use gentle brightening agents like niacinamide (after healing).
• Consult a dermatologist for advanced treatments (e.g., microneedling or laser).
• Be patient — scars can take time to fade.

Final Thoughts

Skin polishing is effective for rejuvenation when performed correctly, but improper technique or poor aftercare can lead to scarring. Protect your skin by choosing qualified professionals, following proper aftercare, and giving your skin the time it needs to heal.
