The Complete Guide on How to Prevent and Treat Facial Scars

Too much collagen creates a raised scar
While a lack of collagen makes an indented one

Remember that time you cut yourself?

Or the spot you squeezed that left a tiny mark behind?

Maybe you nicked yourself shaving, and now you’ve got a stubborn reminder.

Whether it starts as a cut, burn, acne lesion, or an injury from picking (yes, that counts).

A scar can linger long after the skin has “healed” and the redness has settled.

As a skincare specialist, one of the most common questions I hear is: “Can I fade this scar?”

In this article, we’re going to take a clear, science-backed look at scars.

You’ll learn why they form, the main scar types, and how the skin rebuilds itself after injury.

Why we scar

Scarring is part of the body’s natural repair process. When the skin is deeply injured, your body prioritises quickly closing and strengthening the area. The “finish” may not look like normal skin, but it is designed for protection.

Several factors influence how likely you are to scar and how prominent a scar becomes:

• Genetics: Some people naturally produce more collagen during healing, increasing the risk of raised scars.
• Skin tone: Deeper skin tones may be more prone to post-inflammatory hyperpigmentation and certain raised scars (including keloids).
• Systemic inflammation: Ongoing inflammation in the body can increase the risk of hypertrophic scars or keloids.
• Skin conditions: Disorders such as epidermolysis bullosa can make skin fragile and prone to scarring. Hidradenitis suppurativa can also create deeper wounds that scar.
• Age: Collagen production and elasticity decline over time, and healing can be slower.
• Injury depth and location: Deeper injuries and high-movement areas (knees, elbows) are more likely to scar.
• Hormonal changes: Hormones can influence pigment and healing behaviour, increasing the chance of lingering marks or uneven tone.

The good news: while you can’t control every factor, you can influence how well your skin heals by supporting the wound correctly and protecting the area while it repairs.

What is scar tissue?

Scar tissue is not the same as normal skin.

Healthy skin has collagen arranged in a flexible, multidirectional “basket-weave” pattern. Scar tissue forms when collagen is laid down in a more linear, organised-to-close-the-gap pattern. This can result in:

• reduced elasticity (tightness)
• changes in texture (raised or indented areas)
• changes in colour (red, pink, brown, or lighter than the surrounding skin)

Why can scar tissue be painful?

Some scars become sensitive or painful due to:

• Nerve involvement: Nerves may be irritated or injured during the initial trauma, and regenerating nerve endings can later trigger discomfort.
• Prolonged inflammation: Overactivity of repair cells (including fibroblasts) can lead to ongoing tenderness, itching, or thickening.
• Fibrosis: Excess collagen buildup can lead to tissue stiffness and increased sensitivity.

How are scars formed?

Wound healing is a highly coordinated process. Clinically, it is typically described in four phases:

1. Haemostasis
2. Inflammation
3. Proliferation
4. Maturation (Remodelling)

1. Haemostasis phase

This stage begins immediately. Blood vessels constrict to reduce blood loss, platelets gather to form a plug, and fibrin threads reinforce the clot like a natural binding mesh. The goal is simple: stop the bleeding and seal the wound.

2. Inflammation phase

Inflammation is the body’s clean-up and defence response. White blood cells and repair signals flood the area to prevent infection and clear damaged tissue. Swelling, warmth, and tenderness are common and normal.

Inflammation becomes a concern when it is excessive or prolonged, as chronic inflammation can increase pigment changes and disrupt healthy collagen organisation.

3. Proliferation phase

This is the rebuilding phase. New tissue forms are supported by collagen and an extracellular matrix. Typically:

• a protective surface forms
• the wound contracts
• fibroblasts begin producing collagen to reconnect the tissue

This is the stage where scar “architecture” begins to take shape.

4. Maturation (Remodelling) phase

This phase can last for months, sometimes over a year. Collagen is reorganised and strengthened (often shifting from type III to type I collagen), and the scar gradually becomes flatter, softer, and less vascular (less red).

Remodelling typically starts around three weeks after injury, but the final appearance continues to evolve as the scar matures.

Clinical note: wounds often heal more smoothly when kept appropriately moisturised and protected. Maintaining a supportive healing environment helps epithelial cells resurface the area more efficiently.

Exudate management is a key factor in treating patients with difficult-to-heal wounds.

The different types of scars

Scars can be flat, raised, overgrown, or sunken, depending on how collagen is produced and remodelled.

Immature scars

Early scars are often pink or red, sometimes itchy or tender. With good wound care, they usually settle and flatten over time.

Mature scars

These are typically flatter and more stable. They may remain lighter (hypopigmented) or darker (hyperpigmented) than surrounding skin.

Contracture scars

Most common after more extensive burns. The tissue tightens and may restrict movement, particularly over joints.

Hypertrophic scars

Raised, thick scars that stay within the original wound boundary. Hypertrophic scars often develop in areas like the chest, shoulders, and upper back. Some improve over time, but they can take many months to settle.

Keloid scars

Keloids extend beyond the original wound margin and can continue to grow. They are more common in specific genetic backgrounds and deeper skin tones, and may appear months after the injury. They can be itchy, tender, and persistent.

Atrophic scars

Indented, pitted scars are often associated with acne or chickenpox. These occur when underlying collagen or supportive tissue has been damaged, leaving a “dip” in the skin.

Acne scars

Acne, especially cystic acne, can injure deeper layers of the skin. Depending on inflammation and healing response, scarring can be raised, indented, or pigmented.

Stretch marks

These occur when skin expands or contracts quickly (such as during pregnancy or rapid weight changes). They can appear raised or indented, and lighter or darker than the surrounding skin.

To conclude: the naked truth

Scarring is influenced by many factors — including genetics, skin tone, inflammation levels, hormones, age, injury depth, and the extent to which the wound is supported during healing.

Scar tissue forms through a structured four-phase repair process: haemostasis, inflammation, proliferation, and maturation. Each stage has a role in closing the wound, rebuilding tissue, and reorganising collagen to strengthen the area.

Different scar types (immature, mature, contracture, hypertrophic, keloid, atrophic, acne scarring, and stretch marks) reflect different healing patterns. Some settle naturally with time, while others benefit from targeted support and, in some instances, professional treatment options.

The most important takeaway is this: how you care for the skin while it heals can influence how it scars. When you understand the process, you can make smarter decisions — early — to support calmer healing and reduce long-term changes in texture and pigment.

FAQs

1. Can scars on the face fade over time?

Many facial scars do soften and fade, particularly early red or pink scars. However, the outcome depends on scar type, injury depth, genetics, and the extent of protection provided during healing.

2. Why do some scars stay red for months?

Redness often reflects ongoing vascular activity during the remodelling phase. This can persist for months, especially if the area is irritated, unprotected from UV, or healing slowly.

3. What increases the risk of raised scars?

Genetic tendency, deeper injury, prolonged inflammation, tension on the wound, and specific body areas (chest, shoulders, upper back) can all increase the likelihood of hypertrophic or keloid scars.

4. Are acne marks the same as acne scars?

Not always. Many “acne marks” are post-inflammatory hyperpigmentation (colour changes) rather than true scarring. True acne scars involve changes in texture (indentation or raised tissue) from deeper collagen damage.

5. What is the most critical step for preventing visible scarring?

Early wound support matters: minimise friction and picking, keep the area protected, and use daily sun protection once the skin has resurfaced. UV exposure is one of the biggest reasons scars darken and linger.
