Mederma Scar Serum for Old Scars, 1 fl oz — Triple-Action with Vitamin E, Hyaluronic Acid & Niacinamide (lightens, smooths)

Mederma Scar Serum is a concentrated, triple-action topical serum that helps lighten, flatten, and smooth the appearance of old scars using Vitamin E, hyaluronic acid, and niacinamide.

This lightweight serum is formulated to target scars from acne, surgery, and prior injuries by delivering hydration, barrier support, and skin-tone evening ingredients in a single daily routine. Clinically shown to improve the appearance of old scars in as little as two weeks, the serum is intended for scars that are six months or older and works best with twice-daily application over an 8-week course. The formula is dermatologist-backed and comes from the Mederma brand, known for scar-care solutions recommended by U.S. physicians and pharmacists.

How quickly will I see visible changes to my scar?

Individual results vary, but clinical testing showed noticeable improvement for some users in two weeks, with more consistent visible change by four weeks. Optimal outcomes are typically reported after using the product twice daily for the full 8-week period.

• Possible visible improvement in some users at 2 weeks
• More measurable lightening and flattening by 4 weeks
• Recommended twice-daily use for 8 weeks for best results
• Designed for scars aged six months or older

What active ingredients are included and what do they do?

The serum combines Vitamin E, hyaluronic acid, and niacinamide to address several scar concerns: antioxidant protection and skin-conditioning from Vitamin E, hydration and plumping from hyaluronic acid, and tone-evening plus barrier support from niacinamide. Together these ingredients help the surface appearance without invasive procedures.

• Vitamin E: skin conditioning and antioxidant support
• Hyaluronic acid: boosts hydration and skin smoothness
• Niacinamide: helps even skin tone and strengthen barrier
• Concentrated serum base for targeted application

How should I apply the serum and are there usage tips?

Apply a small amount directly to the scar area twice daily — morning and evening — for eight weeks. Clean, dry skin ensures better absorption; follow with sunscreen during daytime use to protect healing skin from UV-related discoloration.

• Use on scars at least six months old for intended results
• Apply to clean, dry skin morning and night
• Pair with daily SPF in the morning to prevent darkening
• Consistency over weeks improves likelihood of visible change

Is this serum suitable for sensitive or acne-prone skin?

The formula is designed to be gentle while delivering active hydration and tone-supporting ingredients, but as with any topical treatment, patch testing on a small area is recommended before broad application. Discontinue use if irritation occurs and consult a healthcare professional for concerns about sensitive skin reactions.

• Gentle, lightweight serum base suitable for daily use
• Patch test recommended for sensitive skin types
• Stop if you experience redness or persistent irritation
• Consult a dermatologist for complex or severe skin conditions

Who is this for: Mederma Scar Serum is aimed at adults seeking a non-invasive approach to reduce the visible signs of older scars—acne marks, surgical lines, and past injury scars—who prefer a clinically tested, ingredient-focused topical option. It’s a fit for people wanting a straightforward twice-daily routine that adds hydration and tone-evening benefits while avoiding more aggressive treatments; however, anyone with very recent wounds, open skin, or concerns about ingredient sensitivities should consult a clinician before use.
