Fractional lasers are one of the most effective methods for reducing acne scars. They work by creating micro-injuries in the skin, which stimulate natural regeneration and rebuilding processes. As a result, the skin gradually becomes smoother, and scars become less visible. Fractional lasers are preferred for removing acne scars because they allow for precise and controlled treatment, minimizing damage to healthy tissue. Compared to traditional methods such as chemical peels or microdermabrasion, they offer deeper and more effective skin remodeling, which is crucial for treating both superficial and deep scars.
There are three main types of fractional lasers used for reducing acne scars:
- Ablative - remove the outer layers of the skin, resulting in intense regeneration and remodeling.
- Non-ablative - work in deeper skin layers without damaging the epidermis, leading to gradual scar reduction with shorter healing times.
- Hybrid - combine both technologies, providing high effectiveness with moderate recovery times.
The different types of fractional lasers allow for individualized therapy tailored to the type of scars and the patient's skin type, resulting in better outcomes and greater treatment comfort.
How do fractional lasers remove acne scars?
Fractional lasers emit a beam of light that is absorbed by water in the skin cells. This controlled tissue damage stimulates repair processes and collagen and elastin production - key proteins for healthy, firm skin.
Each laser works differently:
- Ablative Lasers
Create deep micro-injuries that stimulate intense skin regeneration. They cause epidermal exfoliation, helping to remove scars and smooth the skin surface. They require a longer healing time (7-14 days) but are the most effective for deep atrophic scars.
- Non-Ablative Lasers
Reach deeper skin layers, stimulating skin rebuilding without damaging the epidermis. The skin regenerates gradually, with significantly shorter healing times (1-3 days). Best for individuals with superficial scars and those who cannot afford a long recovery period.
- Hybrid Lasers (Alma Hybrid)
Combination of ablative and non-ablative technologies, acting on both the skin surface and deeper layers. They provide quick results with shorter healing times than traditional ablative lasers (3-7 days). A good option for individuals seeking visible improvement with a moderate recovery period.
What are the effects of removing acne scars with lasers?
- Gradual smoothing of acne scars - the skin becomes more even.
- Improvement in skin structure and firmness - by stimulating collagen production.
- Reduction of post-inflammatory hyperpigmentation - the skin gains a more even tone.
- Reduction of both shallow and deep scars - depending on the technology used.
- Ability to adjust the treatment intensity - to the individual needs of the patient.
- Shorter healing time compared to older methods - especially with hybrid and non-ablative lasers.
Full effects are seen after a series of 3-6 treatments, performed at 4-6 week intervals. Choosing the right laser depends on the extent of the scars, patient expectations, and time constraints related to recovery.
