Acne and Acne Marks: The Real Causes and Effective Treatment Options

Why does acne leave marks in the first place?

When a pimple becomes inflamed under the skin, the body responds with a natural repair process. The problem is that this repair is sometimes not perfect: melanin (the skin pigment) increases in the affected area, or collagen breaks down or builds up unevenly. The result is one of three things:

• Dark spots (post-inflammatory pigmentation): The red or brown color that remains after the pimple has healed. This is not a true scar.
• Depressed scars (atrophic): Collagen has broken down beneath the skin, so it appears as a pit or a line. These are the hardest to treat.
• Raised scars (hypertrophic or keloid): The body produced more collagen than needed, leaving a raised scar. These are less common with acne.

Factors that raise the risk of marks include picking at pimples, delaying treatment, and darker skin, which naturally produces more melanin when inflamed.

The difference between pigmentation and scars, and why it matters

Many people confuse a dark spot with a scar, and this confusion affects how it should be treated. A dark spot is medically known as post-inflammatory hyperpigmentation. It is a change in color only, with no change in skin texture. It has a good chance of improving on its own over time with sun protection. A depressed scar is a change in the structure of the skin itself. It will not go away on its own and needs medical treatment.

Fitzpatrick skin types III and IV (common in our region) are more prone to pigmentation. This means treatment must be chosen carefully, because some procedures can cause the very problem you are trying to fix if they are not applied correctly. Find out your skin type before deciding on any treatment.

What treatment options are available for each type?

There is no single treatment that suits everyone. The choice depends on the type of mark, the depth of damage, and your skin type:

• For dark pigmentation: A chemical peel at concentrations suited to darker skin is one of the most commonly used options. It speeds up skin renewal and breaks down accumulated melanin. Learn more about peel sessions.
• For depressed scars: Microneedling stimulates the body to produce new collagen in the hollow areas.
• For combined concerns: Platelet-rich plasma (PRP) may be used alongside skin renewal techniques to support the skin's natural response.
• For overall radiance: Skin boosters and collagen renewal improve skin hydration and help even out skin tone gradually.

Treatment usually takes more than one session and some patience. Improvement is gradual and real, not instant.

The role of sunscreen in treatment: not optional, but part of the protocol

One of the things people overlook most: sunscreen is not just prevention, it is an essential part of treating pigmentation. The sun stimulates melanin-producing cells and deepens dark spots, even while you are having peels or other treatments. If you don't protect your skin from the sun, your sessions will work at half strength, or you may take much longer to see a difference.

This matters especially during the olive harvest season here in Bethlehem. Many people work outdoors for long hours in the sun, and their skin faces a double stress: ultraviolet rays and temperature changes with the cool autumn weather. Plan your daily skincare routine based on your real needs.

What should you expect from a chemical peel session for acne and acne marks?

A chemical peel is one of the most commonly used procedures for treating acne marks. To keep your expectations realistic:

• During the session: You may feel a mild tingling or burning sensation. This is normal and temporary.
• After the session: Redness and light peeling for a few days (depending on the depth of the peel).
• Number of sessions: Usually between 3 and 6 sessions, 2 to 4 weeks apart, depending on your condition.
• Results: Gradual improvement in skin tone and texture. Pigmentation responds faster than scars.
• Downtime and aftercare: You must avoid direct sun after the session and follow the instructions given by your doctor.

A peel is not suitable for every skin type or every type of mark. Your doctor will decide on the type of peel (superficial, medium, or deep) based on an assessment of your skin.

When should you see a doctor right away?

In certain cases, delaying a visit to a dermatologist or aesthetic doctor can make the problem worse:

• Severe inflammatory acne (cystic or nodular): Painful and deep under the skin. It needs prompt medical treatment before it turns into permanent scars.
• Raised scars or keloids appearing: If you notice that a mark is growing instead of fading.
• Pigmentation getting worse despite using brightening products: There may be an allergy or a reaction to a particular ingredient.
• Any cosmetic product that causes unusual redness or burning: Get a specialist's opinion before continuing to use it.

Remember: products you see on Reels and TikTok are not a substitute for an individual medical assessment. Your skin is unique and needs its own plan.
