How to remove old scars?

Old scars on the face, especially persistent ones, are among the most challenging issues in skincare and skin restoration. Not only do they last over time, but they also appear in various forms such as atrophic scars (pitted scars), hypertrophic scars, and post-inflammatory hyperpigmentation. To achieve optimal results without wasting time, it is essential to correctly identify the appropriate scar removal method based on the scar type and skin condition.

Scar Formation Mechanism

Scarring is a natural part of the body’s healing process, typically progressing through four main stages:

• Hemostasis: Blood vessels constrict and clotting occurs to prevent further bleeding.
• Inflammation: White blood cells migrate to the wound site to clear bacteria and cellular debris. While this response is beneficial, prolonged or excessive inflammation can cause swelling, pain, and impair healing—ultimately increasing the risk of scarring.
• Proliferation: Fibroblasts produce collagen to close the wound. If collagen is underproduced, atrophic (depressed) scars can form; if overproduced, hypertrophic or raised scars may result. Concurrently, capillaries regenerate to nourish new tissue.
• Remodeling: Even after the skin surface has closed, fibrotic tissue continues to accumulate underneath. Without proper intervention, this may lead to permanent scars that persist for years.

Causes of Long-Standing Facial Scars

There are several common causes behind old scars on the face:

• Acne: Especially common during puberty, inflamed or infected acne lesions can cause deep tissue damage, resulting in pitted scars if not treated promptly.

• Chickenpox: Scratching or skin infections during the illness can leave scattered, wide scars across the face.

• Injuries: Burns, falls, or traffic accidents may lead to deep wounds that are difficult to heal, often resulting in large hypertrophic or atrophic scars.

• Surgical Procedures: Even minimally invasive procedures like laparoscopic surgeries can leave scars.

• Other factors: Improper skin care, folliculitis, and untreated skin abscesses may also contribute to the development of permanent scars.

Effective and Safe Methods to Remove Old Facial Scars

Thanks to advancements in technology and medical expertise, removing old facial scars is now possible with greater safety and efficacy. High-tech solutions combined with a personalized treatment plan under the guidance of a trained dermatologist offer the best outcomes.

At Wedo Skin Clinic, we provide a range of proven solutions tailored to different types and severities of scarring:

Fractional CO2 Laser Technology

This cutting-edge solution penetrates deep into the skin layers to stimulate collagen production and resurface the skin. By fractionating the laser beam, this method targets only a portion of the skin at a time—minimizing surface damage. With a wavelength of 10,600 nm, it precisely reaches the dermis and is highly effective for long-standing scars, outperforming traditional CO2 lasers.

Erbium Laser

Operating at a 2940 nm wavelength, the Erbium laser is water-absorbing and gently removes the epidermis and part of the dermis to trigger the skin’s natural healing response. At temperatures above 50°C, collagen fibers shrink and break down, making room for new collagen to form over the next 3–6 months. Simultaneously, damaged surface cells are gradually replaced by new epithelial cells, leaving the skin smoother.

Subcision (Scar Releasing Technique)

Dermatologists use a specialized needle to sever fibrous bands beneath the skin that pull down scarred areas. This allows the skin to lift and encourages natural collagen formation. Subcision can be combined with laser treatments for enhanced results.

TCA Cross

The TCA (Trichloroacetic Acid) Cross technique involves applying a high concentration of acid directly to pitted scars. This promotes deep collagen remodeling and gradual filling of the scar. Ideal for shallow or non-invasive scars, the method offers quick recovery and is cost-effective.

Microneedling with Chemical Peels

This combination treatment creates micro-injuries in the skin while applying chemical solutions to boost collagen and elastin production. It helps fill in scars, reduce pore size, and improve overall skin texture. Especially effective for pitted and atrophic scars.

Mesotherapy

This technique involves injecting a cocktail of vitamins, minerals, amino acids, and bioactive ingredients directly into the dermis. It enhances blood circulation, stimulates collagen and elastin production, and rejuvenates scarred skin.

Conclusion

Removing old scars from the face requires a combination of expert knowledge, modern technology, and personalized treatment protocols. While there’s no one-size-fits-all solution, with accurate diagnosis and the right approach, significant improvements in both skin structure and appearance are achievable.
