Scar Reduction


Scars can be a reminder of a not-so-happy past. They can be uncomfortable and can affect your self-confidence. Fortunately, there are several methods to reduce the look of scars.

In this article, we will explore the techniques and remedies used for scar reduction:

Overview of scarring

Scarring is a common skin damage. It can be caused by injury or medical issues like acne and chickenpox. It can range from minor to severe. People are mainly concerned about scarring on the face. Some scars fade without treatment, but some stay. To reduce the appearance of scars, nonsurgical treatments or surgery might be needed, depending on the location and severity.

Atrophic (depressed) scars are caused by damage under the skin. Hypertrophic (raised) scars are caused by thickening and too much growth at the wound. Keloid scars happen due to collagen production and thickening around a wound. These scars stay even after healing, and can get bigger.

Types of scars

Scars have many causes, like cuts, scrapes, burns, acne or surgery. Knowing the different types of scars is important to treat and reduce them.

  • Hypertrophic scars are raised and can be red to pink. They can appear after an injury or much later, and are more visible on darker skin tones. Treatments include massage and topical creams or silicone sheeting.
  • Keloid scars happen when too much collagen is made during healing. They are often red or purple, and bigger than the site of injury. Steroid injections or laser treatments are needed to reduce them.
  • Atrophic scars are depressed and have breaks in the tissue. Causes include acne or chicken pox. Vitamin C and certain peels or laser treatments may help.
  • Contracture scars occur when a large area is burned. The skin tightens, and the joints may not move well. Reconstruction surgery and therapies are needed here.

Causes of Scarring

A scar is a mark left on the skin from healing wounds. It could be from cuts, burns or medical procedures. Knowing the different causes of scarring helps you prevent it. Let’s explore!

Injury or trauma

Injury or trauma can cause scarring. Cuts, burns, punctures, bites and scrapes can leave scars. To reduce the appearance of these scars, a cosmetic surgeon or dermatologist use advanced techniques like laser technology and fillers.

Other physical injuries, such as surgery, radiation treatment or injections, can also lead to scarring. Not all wounds heal with visible scars. It depends on the individual’s healing process, age, and how prone they are to forming scars.


Acne can cause permanent scarring. To prevent damage to skin, early and continual treatment is essential. When the body produces too much collagen during healing, acne scars form. Types of scars can range from mild to severe:

  • atrophic, like ice pick or boxcar scars;
  • rolling texture scars caused by too much collagen;
  • hypertrophic or keloid scars; and
  • post-inflammatory hyperpigmentation in darker skin tones.

Treatments may include

  • cortisone injections,
  • laser treatments,
  • dermabrasion,
  • chemical peels, or
  • topical ointments.

Scarring is a regular part of healing from surgery. It is when skin cut during the operation does not line up perfectly and hardens. It can look bad or even be permanent, depending on the type of surgery and the person healing.

Surgeons try to make incisions tiny and scars invisible. They use suturing techniques, such as running or crossing sutures. In some cases, special “disappearing” sutures are used to create a fine scar line.

To prevent scarring, surgeons do things right after the operation. This includes applying ointment to cleanse scars and reduce infection. Patients are also instructed to move joints or limbs so that scar tissue can form correctly. Silicone-based wound dressings may be used to reduce scarring over time.


Burns are a common cause of scarring. There are three categories – superficial, partial-thickness and full-thickness burns. The severity of the burn determines the effects.

  • Superficial burns only affect the top layers of skin. These can cause light pigment changes. They can be treated with antibiotic cream or ointment. If the burn is large or painful, medical care is important.
  • Partial-thickness burns penetrate deep into the dermis layer. These burns cause blisters, cracking and white or charred areas. Treating these burns involves protecting them with an ointment. Severe partial-thickness burns may need antibiotics to fight infection and limit scarring.
  • Full thickness burns involve deep charring of all layers of skin and underlying structures. Treatment requires medical professionals due to the risk of infection. Treatment likely involves surgical removal and specialized wound care. This encourages rapid healing and limits scar formation.

Treatments for Scar Reduction

Scar reduction treatments can help make those marks less visible and give you back your confidence. You have many options, from natural remedies to medical treatments. Let’s explore them, so you can choose the one that suits you best:

  • Natural remedies
  • Medical treatments

Topical treatments

Topical treatments can help reduce scarring. But, many scar creams and ointments do not live up to their promises. So, research each product thoroughly before buying.

Chemical peels, retinoid creams, silicone sheeting and gels, steroid injections and over-the-counter products containing Vitamin A derivatives, Vitamin E oil and aloe vera gel are popular topical treatments. Chemical peels remove top layers of skin cells to reduce discoloration. Retinoid creams contain Vitamin A derivatives that encourage cell regeneration. Silicone sheeting and gels reduce hypertrophic scars by reducing blood supply and collagen formation. Steroid injections flatten more pronounced scars when applied with a needle.

Products like BioScar’s Scar Cream, ScarAway Silicone Soft Sheets or Derma E’s Scar Gel can be tried first. But it is best to seek medical advice before opting for more invasive procedures. So, consult your doctor before beginning any treatment regimen for scar reduction.

Laser treatments

Laser treatments can be used to reduce the appearance of severe scars or those that won’t respond to other therapies. These treatments don’t cure the scars, and the number of sessions needed depends on the type and severity of scarring.

Common laser treatments include:

  • Fractional laser skin resurfacing
  • Erbium laser resurfacing
  • Erbium Yag laser resurfacing
  • Pulsed dye lasers
  • Intense pulsed light therapy (IPL)
  • Some applications use radiofrequency energy too.

The goal is to create new collagen in the dermis, which can help reduce irregularities. Before treatment, gentle exfoliation is done, such as chemical peels, microneeding, or microdermabrasion. This prepares the skin for the laser treatment. The intensity of the laser depends on the type chosen and its settings. It can range from mild warming to more aggressive blasts. Most lasers can’t remove deep scars, but they can even out skin texture.

It’s important to follow the instructions given by the specialist and follow the home care routine prescribed. This will help ensure the best outcome after successful stimulation of collagen regeneration.


Injections are a great way to reduce scars, especially for smaller and shallower ones. The type of injection varies, depending on the patient’s needs. It could include corticosteroid, 5-FU or lidocaine injections.

  • Corticosteroid injections reduce pain, swelling and itching.
  • 5-FU blocks collagen and fat cell growth in the dermis.
  • Lidocaine increases blood flow for larger, older scars.

Repeated injections every 4 – 6 weeks for up to six months are often necessary for optimal results.


Surgical treatments for reducing scars include dermabrasion, dermaplaning, laser and light therapy and microdermabrasion. These can help remove the outer layers of skin to reduce the appearance of scarring. Surgery can involve making small incisions into the scar tissue. This can help remove underlying fat or other tissues that add to the contrast of the area. Then, healthy tissue can replace it and help it heal.

Surgeons can use many types of surgery to treat scars, such as:

  • Skin grafting
  • Excisional surgeries
  • Suturing
  • Z-plasty
  • Subcision

Each type has advantages and disadvantages. It is important to discuss the options with the surgeon to find the best approach. In some cases, combining surgery with laser treatments is the best option.

Prevention and Maintenance

Preventing and maintaining scars is crucial. Scar avoidance and care can help diminish existing scars and stop new ones. Here, we’ll go over diverse procedures for scar prevention and upkeep. Plus, we’ll look at the issues connected with it.

Avoiding sun exposure

Sun damage can cause scars and make you look older. To prevent this, it’s best to avoid too much direct sun exposure. When going out in the sun for long periods, cover up with loose clothes, wear a broad-spectrum sunscreen with SPF 15 or higher, and wear wide-brimmed hats.

If you’re planning outdoor activities or travel, try to do it when the sun is not so strong. If you are swimming, apply sunscreen 30 minutes before and then reapply regularly. Even on cloudy days, don’t forget to wear sunscreen. UV rays can still cause damage.

Once you leave the sun, moisturize your skin right away. Look for natural oils such as rosehip seed oil, jojoba oil, almond oil and vitamin E to keep your skin hydrated.

Eating a healthy diet

A healthy diet can help reduce scars. Vitamins like C, A and E are good for skin health. Omega-3 fatty acids found in salmon, spinach, kale and sunflower seeds can aid healing.

Protein helps build collagen which is needed for proper skin cell regeneration. Beans, nuts and lentils contain amino acids. Vitamin D helps store proteins and is found in eggs, mushrooms, cheese, fortified cereals and sunlight.

A Mediterranean diet full of whole grains, fruit and veg helps blood flow and speeds healing. Drink lots of fluids to avoid dryness which can make scars more visible.

Using sunscreen

Sunscreen is a must for keeping scars at bay. Not just to stop sunburns, but to stop scars from getting worse too. If you have existing scars, use sunscreen before going into the sun to guard against any further damage and stop the skin in those areas from darkening.

Use a broad-spectrum sunscreen with an SPF of 15 or higher. Make sure it’s sweat- and water-resistant. Apply it generously to scarred or exposed skin 15-30 minutes before venturing out and reapply every two hours or after swimming or sweating a lot. Wear long sleeve shirts and a hat while outside to avoid overexposure. If you follow these steps consistently, your scars should heal better and be less visible in time.

Avoiding picking at scars

Picking at scars is bad; it can make them worse and cause more scarring. To avoid this, try to resist the urge. If you do feel the need to touch or pick the scar, adjust your behaviour before you do.

Here are a few tips to help:

  • Keep your hands busy.
  • Distract yourself by doing something else.
  • Put clothes on to cover it.
  • Use anti-itch creams.

If self-care isn’t enough, visit your GP or dermatologist. In serious cases, medication may be helpful.


To sum it up, there are many ways to reduce the look of scars. This can take a few years as scar tissue needs to heal. The methods that work best depend on the age and type of the scar, plus your skin type. Options include:

  • Products applied to the skin
  • Surgery such as lasers or collagen injections
  • Home remedies like natural oils or dietary supplements

Scar reduction takes patience and dedication. With effort, most scars can be made less visible. Before starting any treatment, it’s wise to get advice from a medical professional, as they can help you make sure it’s safe and effective. Plus, you don’t want to end up with an infection or a bad reaction to the treatment.
