Why Does Acne Leave Scars?
Acne scars develop when inflamed blemishes damage the skin's deeper layers. As the skin attempts to repair itself, it may produce either too much collagen (leading to raised, hypertrophic scars) or too little (resulting in the depressed, pitted scars known as atrophic scars). The type and severity of acne, as well as how quickly it is treated, both influence the likelihood of scarring.
Types of Acne Scars
Atrophic (Depressed) Scars
- Ice pick scars — deep, narrow pits that extend into the dermis.
- Boxcar scars — broad, rectangular depressions with sharply defined edges.
- Rolling scars — wide, wave-like undulations in the skin surface.
Hypertrophic (Raised) Scars
These form when the body overproduces collagen. They sit above the skin surface and are more common on the chest, shoulders, and jaw.
Post-Inflammatory Hyperpigmentation (PIH)
Flat dark marks left after a spot heals. Technically not true scars (no structural damage), but they are the most common concern and respond well to topical treatment.
The Best Treatments for Acne Scars
1. Topical Scar Treatments
For raised and post-inflammatory acne scars, scar-specific formulations are highly effective. Contractubex Gel contains allantoin, heparin, and cepae extract — a combination clinically shown to soften raised scar tissue, reduce redness, and improve overall skin texture. Apply twice daily with gentle massage for at least 3 months.
2. Brightening Creams
For flat, hyperpigmented acne marks, a brightening cream targets melanin overproduction at the source. NoScar Cream is specially formulated to reduce post-acne discolouration while supporting skin barrier repair. Use morning and evening after cleansing.
3. Chemical Exfoliation (AHAs & BHAs)
Glycolic acid (AHA) and salicylic acid (BHA) accelerate cell turnover, gradually surfacing fresher, more even-toned skin. Look for products with 5–10% concentrations for at-home use. Use no more than 2–3 times per week to avoid irritation.
4. Retinoids
Vitamin A derivatives stimulate collagen production and speed up cell renewal. Low-strength retinol is available over the counter; prescription tretinoin offers stronger results for deeper scarring. Always introduce slowly and pair with SPF.
5. Sun Protection (Non-Negotiable)
UV rays darken pigmentation and slow scar healing. A broad-spectrum SPF 30+ applied every morning — even on dull days — is the single most important step in any scar-fading routine.
Building an Acne Scar Routine
- Morning: Gentle cleanser → brightening treatment (e.g., NoScar Cream) → SPF 30+
- Evening: Double cleanse → chemical exfoliant (2–3x/week) or retinol → scar gel (e.g., Contractubex Gel) → moisturiser
Realistic Timelines
- PIH (dark marks): 3–6 months with consistent topical use.
- Mild raised scars: 6–12 months with scar gel and massage.
- Deep atrophic scars: Often require in-clinic procedures (microneedling, laser, fillers) alongside topical care.
When to See a Dermatologist
If over-the-counter treatments show no improvement after 3–6 months, or if you have widespread, deep scarring, a dermatologist can recommend professional treatments such as microneedling, laser resurfacing, or chemical peels.
Key Takeaways
Treating acne scars requires patience, the right products, and consistent sun protection. Start with targeted topical treatments such as Contractubex Gel for raised scars and NoScar Cream for dark marks, and give your skin at least 3 months before assessing results.
