Can over-the-counter creams or gels reduce acne scars?

Yes, over-the-counter (OTC) creams and gels can help reduce the appearance of acne scars, particularly mild ones. Here's how they work and what to look for:

• Retinoids (Adapalene): Stimulates cell turnover, improves skin texture, and reduces hyperpigmentation associated with scars.
• Vitamin C: A powerful antioxidant that brightens dark spots, evens out skin tone, and promotes collagen production to improve scar texture.
• Niacinamide: Reduces inflammation and hyperpigmentation while improving the skin’s elasticity and barrier function.
• Silicone Gel or Sheets: Creates a protective barrier over scars, promoting healing and reducing the thickness and redness of scars over time.
• Glycolic Acid: An alpha-hydroxy acid (AHA) that exfoliates dead skin cells, smooths rough textures, and lightens post-acne marks.
• Salicylic Acid: A beta-hydroxy acid (BHA) that gently exfoliates the skin, unclogs pores, and reduces discoloration from acne scars.
• Kojic Acid: Helps lighten dark spots and hyperpigmented scars by inhibiting melanin production.
• Azelaic Acid: Effective for treating post-inflammatory hyperpigmentation (PIH) and lightening dark marks caused by acne.

Limitations of OTC Treatments:

• They are most effective for hyperpigmentation or mild scars but have limited impact on deeper, pitted scars.
• Results take time and consistent use—usually several weeks to months.

Usage Tips:

• Patch test new products to check for irritation.
• Combine with sunscreen daily, as scar treatments can make skin more sensitive to UV damage.

For Severe Scars: Professional treatments like microneedling, laser therapy, or chemical peels may be required. Consult a dermatologist for personalized advice.
