Laser and Advanced Treatments for Acne Scars, Marks and Skin Texture
Acne scarring and post-acne marks can be a source of frustration and affect confidence. Once active acne is well controlled, treatment can focus on improving the appearance of scars and restoring smoother, clearer skin.
At Stephanie Ho Dermatology, we offer advanced treatments for acne scars, tailored to the type of scarring and skin type. In addition to improving scars, these treatments often also enhance:
- skin texture
- pore size
- pigmentation
- fine lines and early signs of ageing
Types of acne scars and marks
Acne can leave behind different types of marks and scars, each requiring a specific treatment approach.
Brown marks (post-inflammatory hyperpigmentation)
Dark brown marks are common, especially in Asian skin, after acne has healed.
We use picosecond laser technology to:
- target pigmentation
- break down excess melanin
- fade dark marks effectively
This helps restore a more even skin tone.
Red marks (post-inflammatory erythema)
Red or pink marks are often seen in the early stages of acne healing.
The pulsed dye laser is highly effective in:
- targeting redness
- reducing visible blood vessels
- accelerating resolution of red marks
Noticeable improvement is often seen after 2 to 4 sessions.
Depressed acne scars (atrophic scars)
Depressed scars such as rolling, boxcar, and ice-pick scars occur due to collagen loss following inflammation. We use a combination of advanced treatments:
Fractional CO2 laser
- creates controlled micro-injury in the skin
- stimulates new collagen production
- resurfaces and smoothens the skin
Radiofrequency microneedling (RF)
- delivers energy into deeper layers of the skin
- stimulates collagen and elastin production
- improves both acne scars and residual redness
This is particularly useful for:
- mild to moderate acne scars
- patients with sensitive or Asian skin types
Collagen-stimulating injectables (biostimulators)
- stimulate the skin to produce new collagen over time
- improve skin thickness and structure
- help soften and lift atrophic scars
These are especially useful for:
- rolling scars
- boxcar scars
- overall skin quality improvement
These treatments help to:
- improve scar depth
- refine skin texture
- restore a smoother, more even skin surface
Multiple sessions are usually required for optimal results.
| Type of mark or scar | Treatment used |
|---|---|
| Brown marks (post-inflammatory hyperpigmentation) | Picosecond laser technology |
| Red marks (post-inflammatory erythema) | Pulsed dye laser |
| Depressed acne scars (atrophic scars) | Fractional CO2 laser, radiofrequency microneedling, collagen-stimulating injectables |
Important considerations before treatment
To minimise the risk of complications such as post-inflammatory pigmentation:
- avoid sun exposure and tanning before and after treatment
- use strict sun protection
- follow all pre- and post-treatment instructions
Before starting treatment, your dermatologist will discuss:
- expected outcomes
- number of sessions required
- potential downtime
- possible risks and complications
Our approach prioritises effective results with the lowest possible risk, especially for Asian skin types.
Why combination treatment works best
Acne scarring often involves:
- pigmentation
- redness
- textural changes
Combining different modalities allows us to:
- target multiple components of scarring
- achieve more comprehensive improvement
- optimise overall skin quality

Frequently Asked Questions
How many sessions will I need?
It depends on the type of scarring. Red marks often show noticeable improvement after 2 to 4 sessions, while depressed acne scars usually require multiple sessions for optimal results. Your dermatologist will discuss the number of sessions required before treatment begins.
When can I start acne scar treatment?
Treatment focuses on scars once active acne is well controlled. At that point, treatment can be directed at improving the appearance of scars and restoring smoother, clearer skin.
Is there downtime, and what should I do before and after?
Potential downtime is discussed with you before starting treatment. To minimise the risk of complications such as post-inflammatory pigmentation, avoid sun exposure and tanning before and after treatment, use strict sun protection, and follow all pre- and post-treatment instructions.
Which treatment is used for my type of scar?
Brown marks are treated with picosecond laser technology, red marks with the pulsed dye laser, and depressed atrophic scars with a combination of fractional CO2 laser, radiofrequency microneedling and collagen-stimulating injectables.
Are these treatments suitable for Asian or sensitive skin?
Yes. Radiofrequency microneedling is particularly useful for mild to moderate acne scars and for patients with sensitive or Asian skin types, and our approach prioritises effective results with the lowest possible risk, especially for Asian skin types.
