How long does acne scar treatment take? Factors influencing treatment duration
CONTENT
Treating acne scars is not a quick process—it requires patience, especially in cases of severe or long-standing scars. Every skin type heals at a different pace, and the skin needs adequate time to regenerate and repair itself. So, how long does acne scar treatment actually take? Let’s explore to better prepare for the journey toward smoother skin.
How long does acne scar treatment take?
Acne scars cannot be erased in a single session. For mild to moderate scars, treatment typically takes 3–8 months, with about 3–8 sessions scheduled one month apart. However, in severe or long-standing cases, the process may extend to a year or longer, as improvement happens gradually.
The one-month interval between sessions is based on the principle of creating controlled micro-injuries to stimulate skin regeneration. This process follows four healing phases, with the proliferation phase (collagen formation and scar filling) beginning around day 4 and lasting up to day 21. This stage is critical in determining recovery outcomes. Hence, an interval of 4–6 weeks between treatments is optimal, allowing the skin to fully regenerate before the next procedure.
It’s important to note that scar healing depends not only on the number of sessions but also on various personal factors. Each patient requires a tailored treatment plan, guided and monitored by a qualified dermatologist.
Factors Affecting Acne Scar Treatment Duration
- Scar type & severity
Acne scars are categorized into three main types: icepick, rolling, and boxcar scars. Many patients have a combination of scar types, which means treatment may involve multiple techniques rather than a single solution. Consulting with a dermatology clinic ensures accurate assessment and personalized protocols.
- Scar age
Newer scars are easier to treat since they contain fewer fibrotic tissues. In contrast, old scars are more fibrotic and resistant, requiring subcision and multiple sessions for noticeable improvement.
- Patient’s age
The ideal age for acne scar treatment is 15–35 years, when the skin’s healing capacity and collagen production are at their peak. After age 35, wound healing slows due to reduced immune activity and collagen synthesis, making treatment longer and more complex.
- Post-treatment care
Proper aftercare significantly impacts results. Following medical instructions—such as using growth factor creams and applying sunscreen consistently—helps the skin recover effectively and maintain long-term improvement.
When are results visible?
The most anticipated outcome is scar filling. While no treatment can achieve 100% scar removal, modern technologies combined with medical expertise can restore skin smoothness by up to 90%. Depending on the scar type and chosen method, results may become visible within 3 weeks to 3 months, especially for long-standing scars.
Scar remodeling is a gradual process. With each session, collagen production increases, progressively filling the scar tissue. Patience and completing the prescribed treatment course are key to optimal results.
Aftercare Guidelines for Acne Scar Treatment
1. Sun protection
Treated skin is highly sensitive to UV rays. During the first 2 days, sunscreen should not be applied; instead, use thick cotton masks or dark clothing for protection. From day 2 onward, apply broad-spectrum sunscreen SPF 30+ daily, even indoors.
2. Gentle skincare
Choose mild, non-irritating products free from harsh chemicals. Avoid scrubs or products with strong active ingredients such as BHA, AHA, retinol, tretinoin, vitamin C, hydroquinone, arbutin, or benzoyl peroxide for at least 1–2 weeks.
3. Cleansing protocol
-
First 24 hours: Skin may feel tight, red, or slightly itchy. Cleanse once with saline solution, pat dry with sterile gauze, and apply recovery cream 2–3 times daily.
-
After 24 hours: Cleanse 2–3 times daily with mild water. Avoid hot water or harsh cleansers that strip the skin barrier.
4. General precautions
-
Avoid heavy makeup and minimize exposure to dust and sweat.
-
Stay hydrated with at least 2 liters of water daily to support collagen synthesis.
-
Do not pick or scratch scabs. Natural peeling begins after 5 days; allow it to shed on its own to prevent worsening scars.
-
Avoid exfoliation, steaming, or harsh treatments during recovery.
Conclusion
The duration of acne scar treatment depends on scar type, severity, age, and skin’s regenerative capacity. On average, treatment may take several months to over a year, especially for deep, long-standing scars. Following a personalized treatment plan and adhering to proper aftercare are crucial for success. At Wedo, our dermatologists provide expert assessment and tailored protocols to maximize results and restore confidence in your skin.
FAQs on Acne Scar Treatment Duration
1. Why does treatment require multiple sessions instead of just one?
Because each session targets only part of the scar tissue, allowing gradual collagen stimulation and healing. Staging treatments prevents excessive skin damage and ensures safer recovery.
2. Can the interval between sessions be shortened?
No. The skin requires at least 4–6 weeks to complete collagen regeneration after each treatment. Shortening the interval may reduce effectiveness and increase irritation risks.
3. Which age group responds best to acne scar treatment?
The 15–35 age group generally shows the best response due to stronger healing capacity and collagen production. After 35, improvements are still possible but slower.
4. Is a personalized treatment plan necessary?
Yes. Scar type, skin condition, and healing rate vary by individual. Personalized protocols ensure targeted treatment and better results.
