Mederma Scar Serum for Old Scars, 1 fl oz — Triple-Action with Hyaluronic Acid & Niacinamide for Visible Lightening

Mederma Scar Serum is a concentrated triple-action topical serum formulated with Vitamin E, hyaluronic acid, and niacinamide to visibly reduce the appearance of old scars and discoloration.

Designed for scars that are six months or older, this lightweight serum targets discoloration, texture, and hydration to help skin look smoother and more even. Clinically shown to improve the appearance of old scars in as little as two weeks with consistent use, the formula combines three active ingredients that work together to hydrate skin, support surface renewal, and promote a more uniform tone. Applied twice daily for up to eight weeks, Mederma Scar Serum offers a focused at-home option for acne marks, surgical scars, and other healed injuries.

How quickly will I see changes when I use this scar serum?

Results vary by scar type and skin, but clinical testing showed visible improvement in the appearance of old scars in as little as two weeks with regular application. More noticeable lightening, flattening and fading are typically reported within four weeks when used twice daily.

• Clinically shown improvement in as little as two weeks
• Visible lightening and flattening in about four weeks for many users
• Best results with twice-daily use for up to eight weeks

What do the active ingredients do for scarred skin?

The serum combines Vitamin E for antioxidant support, hyaluronic acid for hydration and plumping, and niacinamide to help even skin tone. Together they address multiple visible features of scars—texture, moisture balance, and discoloration—without heavy residue.

• Vitamin E helps nourish and condition the surface of the skin
• Hyaluronic acid attracts and holds moisture to improve skin texture
• Niacinamide supports a more uniform skin tone and minimizes discoloration appearance

How do I apply Mederma Scar Serum for best results?

Apply a small amount to clean, dry skin over scars that are at least six months old. Massage gently twice daily—morning and night—for targeted coverage, continuing use for eight weeks to assess improvement.

• Use only on healed scars (six months or older)
• Apply to clean, dry skin twice daily—morning and evening
• Consistency for up to eight weeks recommended for best visible results

Will this serum work on different types of scars like acne or surgical marks?

This concentrated serum is formulated to improve the visible appearance of a range of older scars by addressing discoloration, texture and hydration. While outcomes depend on scar age and skin type, many users report measurable improvement across acne scars, surgical scars, and scars from past injuries.

• Suitable for acne-related scars and post-surgical or injury scars six months or older
• Targets discoloration, raised texture, and dryness-related appearance
• Professional recommendations and clinical testing support its use for older scars

Who this is for: Mederma Scar Serum is aimed at adults seeking a topical, non-invasive approach to reduce the visible signs of older scars and uneven tone. It fits into a daily skincare routine for people who want a targeted product that hydrates while addressing the look of scars, and is appropriate for those who prefer dermatologist-backed, clinically studied solutions. It is not intended for fresh or open wounds; consult a healthcare professional if you have concerns about scar healing or underlying skin conditions.
