Introduction
Acne scarring is one of the most common skin concerns we hear about at Ametrine Aesthetics Newcastle. For many people, the acne itself is a distant memory, but the marks it left behind are still visible every day in mirrors, photographs and natural light. That gap between how you feel about your skin and how you want to feel about it is exactly what our team is here to help close.
SkinPen microneedling is FDA-cleared specifically for the improvement of acne scars. That is not a marketing claim; it is a determination made by the US Food and Drug Administration based on published clinical trial data. At Ametrine Aesthetics Newcastle, we use SkinPen because it gives our clients access to the most evidence-backed microneedling available for acne scar treatment.
This guide covers what you need to know before booking: which scar types respond best, how the treatment works, what results are genuinely realistic and how many sessions are likely to be needed.
Understanding Acne Scar Types
Acne scars are not all the same, and the type of scarring you have plays a significant role in how well it responds to microneedling and what level of improvement you can realistically expect. At Ametrine Aesthetics Newcastle, our team assesses your scar type during your consultation to ensure the treatment plan is appropriate for your specific concern.
Rolling Scars
Rolling scars create a wave-like, undulating surface across the skin. They are caused by fibrous tethering bands that pull the skin downward in an irregular pattern. Rolling scars tend to respond well to SkinPen microneedling because the collagen-stimulating response helps remodel the tissue beneath the surface, progressively smoothing the texture over multiple sessions.
Boxcar Scars
Boxcar scars have defined, angular edges and a flat base. They range from shallow to moderately deep. Shallow to moderate boxcar scars respond well to SkinPen because new collagen can gradually fill the base of the depression over time. Deeper boxcar scars may require a greater number of sessions or a combined treatment approach for the most meaningful improvement.
Ice Pick Scars
Ice pick scars are narrow, deep channels in the skin. They are the most challenging acne scar type to treat with any single intervention. SkinPen improves the overall skin texture and quality around ice pick scars, but very deep ice pick scars may not respond fully to microneedling alone. At Ametrine Aesthetics Newcastle, we will give you an honest assessment of what SkinPen can achieve for your scar type during your consultation, including whether a combination approach might serve you better.
Post-Inflammatory Hyperpigmentation
Post-inflammatory hyperpigmentation (PIH) is the flat, discoloured marking left after acne resolves. This is not structural scarring but is often perceived as such. SkinPen can help to improve overall skin tone and reduce the appearance of PIH, particularly when combined with appropriate medical-grade skincare. Our team at Ametrine will clarify the distinction during your consultation and set realistic expectations for both concerns.
How SkinPen Promotes Acne Scar Improvement
SkinPen creates thousands of controlled micro-channels in the skin using ultra-fine, single-use sterile needles. This triggers the skin’s natural wound-healing cascade, which unfolds in three overlapping phases:
- Inflammatory phase: The skin initiates its repair process, increasing blood flow and activating fibroblast cells that are responsible for producing structural proteins
- Proliferative phase: Fibroblasts produce new collagen and elastin fibres, gradually rebuilding the dermal structure beneath the scar tissue
- Remodelling phase: Over weeks and months, the new collagen matures, reorganises and contracts, progressively softening and filling the scar from beneath
Because this process relies on the skin’s own biology, results develop gradually. The most significant improvement in acne scar visibility typically occurs three to six months after completing a full treatment course, as the new collagen reaches full maturity.
What Results Are Realistic?
At Ametrine Aesthetics Newcastle, we set honest expectations. Our goal is always to give clients an accurate picture of what treatment can achieve so that the results feel meaningful rather than disappointing.
SkinPen microneedling will not erase acne scars completely. The aim is progressive, meaningful improvement rather than complete removal. Clients who complete a full course at Ametrine typically report:
- Scar edges that appear softer and less defined in natural and direct light
- Improved overall skin texture across the treated area
- A more even skin tone and improved radiance
- Reduced depth in rolling and moderate boxcar scars
- Increased skin firmness and overall skin quality
The degree of improvement will vary depending on scar type and depth, skin type and tone, how consistently the treatment course is completed, and the skincare regime followed between sessions at Ametrine.
Before and After Expectations: A Realistic Timeline
| Timepoint | What to Expect |
| After session 1 | Redness and warmth for 24 to 48 hours. Early healing phase begins. Skin feels tight |
| Days 4 to 7 post-session | Redness settles. Mild dryness or flaking as skin renews. Texture feels cleaner |
| Weeks 2 to 4 | Skin appears brighter and more hydrated. Early collagen response underway |
| After session 2 to 3 | Redness and warmth for 24 to 48 hours. The early healing phase begins. Skin feels tight |
| Completing the full course | Meaningful reduction in scar prominence. Smoother, more even overall skin surface |
| 3 to 6 months post-course | Peak collagen maturation. Most significant improvement in scar depth and skin quality |
How Many Sessions Are Needed for Acne Scars?
Acne scar treatment requires more sessions than general skin quality improvement because the goal is structural remodelling of scar tissue rather than surface-level collagen stimulation. At Ametrine Aesthetics Newcastle, the typical recommendation for acne scar treatment is 4 to 6 sessions spaced 4 to 6 weeks apart.
Clients with mild to moderate rolling or shallow boxcar scarring may see meaningful improvement within 4 sessions. Those with more significant or widespread scarring are likely to benefit from 5 to 6 sessions and may see continued improvement with annual maintenance treatments.
Our team will assess your specific scarring during your consultation at Ametrine and recommend the most appropriate number of sessions based on what we observe, not a predetermined package.
When SkinPen Alone May Not Be Sufficient
It is important to be honest about the limitations of any single treatment. For some acne scar types and severities, SkinPen alone may not produce the level of improvement a client is hoping for. In these cases, our team at Ametrine Aesthetics Newcastle may discuss:
- Combining SkinPen with additional treatments such as chemical peels or PRP to enhance the collagen response
- Targeted approaches for deep ice pick scars before or alongside microneedling
- A longer treatment course with maintenance sessions for patients with significant scarring
Our approach at Ametrine is always to recommend what we genuinely believe will produce the best outcome for your skin, not simply to book treatments. If a combination approach is likely to serve you better, we will say so.

Frequently Asked Questions
No treatment can completely remove structural acne scars. SkinPen can produce meaningful improvement in scar depth and texture over a treatment course, but the goal is significant reduction rather than complete erasure.
Most clients need between 4 and 6 sessions, spaced 4 to 6 weeks apart. The exact number depends on scar type, depth and extent, and will be recommended during your consultation at Ametrine.
Rolling scars and shallow to moderate boxcar scars respond best. Ice pick scars are the most challenging and may require a combination approach. Ametrine will assess your scar type during consultation.
No. Microneedling over active breakouts risks spreading bacteria through the micro-channels. Our team will advise on the right timing once your acne is stable.
Initial improvements may be visible within two to four weeks. The most significant improvement develops over three to six months after completing the full course as new collagen matures.
Chemical peels are more effective for PIH and surface renewal; SkinPen is more effective for structural scars. Both are available at Ametrine and our team can advise on the right option or a combination approach.
