As a surgeon, you can imagine I've had a lot of conversations about scars over the years.

Scars are a natural part of the body's healing process, serving as a testament to its ability to repair and regenerate. While they may mark the end of an injury, or in my case, a transformative surgical procedure, for many, scars signify the beginning of a journey towards aesthetic or emotional recovery. 

Scar creams prominently line shelves with promises of fading those unwanted reminders. But are these creams truly effective, or are we simply chasing a fleeting hope? Furthermore, are there other natural remedies that may help heal facial scars?

Let’s get into the world of scar care.

The Science Behind Scar Creams

First it’s helpful to understand what scars actually are—and why they behave differently from normal skin.

When your skin is injured—whether through a cut, surgery, or acne—the body rushes to repair the damage. This healing process happens in stages: inflammation, tissue formation, and remodeling. During this process, your body produces collagen, a fibrous protein that acts like scaffolding to close and reinforce the wound.

But here’s the catch: the collagen in scars is laid down quickly and unevenly, which is why scar tissue looks and feels different. It tends to be thicker, less elastic, and lacks key structures like oil glands and pigment cells. That’s why scars can appear drier, discolored, or raised, and why they don’t behave like normal skin.

Because of this, scar care focuses on:

  • Hydration to keep scar tissue soft and flexible
  • Regulating collagen production to prevent thick or raised scars
  • Reducing discoloration caused by uneven melanin production
  • Protecting the scar from sun exposure, which can worsen pigmentation

Science-Backed Solutions for Scarring

Scar creams promise a range of benefits, from lightening the scar’s appearance to improving its texture. To understand their effectiveness, it's crucial to delve deeper into the ingredients that you should look for in a scar cream. 

  • Silicones: Silicones form a breathable, protective layer over the scar. This serves two primary purposes. First, it ensures the scar remains hydrated by trapping moisture. Hydrated scars tend to be softer and less pronounced. Second, silicones have been shown to regulate the production of fibroblasts and collagen, essential components in scar formation. Regular and prolonged use of silicone-based products can prevent the development of raised scars like keloids or hypertrophic scars.
  • Allantoin: Found in many scar creams, allantoin helps to soften keratin in the skin, making the skin feel smoother and more hydrated. This can be especially useful ingredient for thick or raised scars.
  • Sunscreen: Scars are vulnerable to the sun’s UV rays. Since they have a different cellular structure than regular skin, scars can darken or discolor faster when exposed to the sun. Regular application of a broad-spectrum sunscreen, preferably SPF 30 or higher, can prevent this from happening. A sunscreen with zinc oxide or titanium dioxide can provide a physical barrier, offering better protection for scarred areas.
  • Hydroquinone: For scars that have left a mark darker than the surrounding skin, hydroquinone can be a boon. It reduces the melanin production in the skin, which can lighten the darkened scar tissue. However, users should note that prolonged use can sometimes lead to skin discoloration or irritation. Therefore, it's recommended to use this under dermatological supervision.
  • Vitamin E: A popular and readily available remedy, vitamin E is a potent antioxidant. Though many swear by its efficacy, scientific research is mixed. While it can keep the skin moisturized, which can aid in flexibility and softening of the scar, there is little evidence backing up claims that vitamin E will heal scars after they’ve formed. Some older studies found that vitamin E can be beneficial if used on a wound following surgery, before scar tissue can develop, especially when used alongside other antioxidants that fight free radicals and support healing and collagen remodeling, like vitamin C.
  • Peptides: Modern scar creams may also contain peptides, small protein fragments that can signal skin to produce more collagen. Enhanced collagen production can help in the remodeling phase of scar healing, potentially refining the scar's appearance.

Treatment Considerations

The efficacy of scar creams is also influenced by consistent and timely application. Beginning treatment once a wound has healed but before it has fully matured into a scar can yield better results. 

Additionally, individuals should understand that while scar creams might lead to improvements, complete elimination of the scar is often not attainable. Factors like genetics, age, location of the scar, and depth of the original wound all play roles in how effective these treatments can be. 

In any case, consultation with a dermatologist or skincare specialist can offer personalized advice, ensuring that you are using the right products in the correct way to maximize benefits.

Natural Remedies for Scar Healing

Nature has blessed us with numerous remedies that have been traditionally used to heal and improve skin ailments. When it comes to scars, especially on the face, people often lean towards natural treatments, hoping for a gentler yet effective approach. Let’s further explore these natural treatments, their benefits, and their limitations.

  • Honey: The therapeutic properties of honey go back thousands of years. Honey is a natural humectant that keeps the scar hydrated, accelerating tissue regeneration. Especially when raw and unprocessed, honey retains its enzymatic properties and antioxidants which can aid skin healing. Manuka honey, in particular, has a high concentration of these antibacterial properties that reduce the risk of infection and inflammation during scar healing. Applying it on scars can maintain a moist environment, crucial for scar improvement. However, its sticky nature means it’s best used during nighttime or under occlusive dressings.
  • Aloe Vera: This versatile plant has more to offer than just sunburn relief. Aloe Vera gel contains polysaccharides that stimulate skin repair. While daily application may soften and improve scar elasticity, it’s important to make sure it is pure—apply directly from the plant or use high-quality aloe vera gel without additives for the best results. Remember, though, while it aids hydration and the repair process, it may not dramatically alter scar appearance.
  • Onion Extract: The benefits of onion go beyond flavoring our dishes. Onion extract contains an antioxidant shown to influence collagen production and reduce scar height, redness, and hardness. It’s often combined with ingredients like allantoin in scar gels, where studies suggest it may support wound healing and help prevent raised scars when used early and consistently over several months. Some commercial scar gels combine onion extract with other ingredients like silicone and Aloe to amplify benefits.
  • Gentle Exfoliators: Gentle exfoliation can help fade scars over time by removing pigmented cells and minimizing uneven skin texture. Scars can often have a different texture than surrounding skin due to irregular collagen formation during healing. By exfoliating, and promoting the removal of the upper layer of skin cells, scar texture and uneven tone become less noticeable. Enzyme-based exfoliants can do this naturally and gently, without irritating healing skin. Exfoliation also enhances the absorption of scar-reducing ingredients for a more even appearance over time.
  • Massage: Beyond the feel-good factor, massages can be therapeutic for scars. Gentle circular motions can increase blood flow, potentially speeding up the healing process. Moreover, massaging can break down some of the fibrous tissue making scars less raised. Silicone scar sheets sometimes recommend accompanying massage for enhanced benefits.
  • Lavender Oil: Beyond its calming aroma, Lavender is sometimes cited for scar improvement. Its alleged anti-inflammatory properties can help in the initial phases of wound healing. However, essential oils can be potent, so it’s important to dilute them with carrier oils like almond or jojoba before application.
  • Coconut Oil: Often used for its hydrating and anti-inflammatory properties, virgin coconut oil may help soften scar tissue and support the skin’s natural repair process. It creates a moisture-rich barrier that can keep healing skin pliable and protected. Some early research also suggests it may support collagen remodeling. However, it is highly comedogenic and may clog pores, making it a less suitable option for acne-prone or sensitive facial skin. Use sparingly and only after the wound has fully closed.

Natural Considerations

While natural remedies offer a more holistic approach, it’s imperative to remember that individual reactions can vary. Some might find relief and see improvements, while others might experience sensitivities. 

Make sure you wear clothing or hats to protect your scars from sun exposure to prevent further discoloration.

Be patient; natural remedies may take weeks or months for noticeable results.

Healing is a Personal Journey

The journey of scar management is deeply personal, and the approach to healing varies for everyone.

Science has made remarkable strides in understanding skin regeneration and scar formation, offering innovative treatments to improve skin texture and appearance. At the same time, natural remedies, backed by centuries of anecdotal use, provide a gentler alternative, though results can vary.

The key is to set realistic expectations.

Scars often can’t be erased completely, but with the right approach, they can be softened, lightened, and improved.

While the search for the perfect scar solution may not yet exist, it’s essential to remember that scars are part of our stories, adding depth to our narratives and resilience to our spirits. Whether you choose to embrace your scars as part of your unique journey or work toward minimizing their appearance, your choice is valid—deserving of understanding, support, and respect.
