Frequently asked questions

Clear answers before your visit.

Why does acne sometimes leave pitted scars?

Pitted acne scars develop when inflammation damages collagen and the skin does not replace enough of it during healing. Deep acne lesions and picking at spots can increase this risk. These texture changes are lasting, although treatment may soften their appearance. An individual assessment helps determine whether microneedling is suitable for the type and depth of your scars.

How can I tell whether I have acne scars or just red or brown marks?

Acne scars change the skin’s texture, while red or brown marks mainly change its colour. Marks may fade over time, whereas depressions or raised areas generally persist. Both can occur together and may need different approaches. An assessment helps distinguish them and identify appropriate care rather than assuming that microneedling is the right treatment for every post-acne mark.

How can I prevent new scars if I still get acne?

The main ways to reduce new scarring are to treat acne promptly and avoid squeezing or picking at spots. Gentle skin care and sun protection also help limit irritation and lingering pigmentation. Seek medical advice if lesions are deep, painful or leaving depressions. Microneedling does not replace acne treatment, and active inflammation usually needs to be controlled before scar treatment begins.

Can microneedling completely remove acne scars?

Microneedling may improve the appearance of some depressed acne scars, but complete removal cannot be promised. Controlled micro-injuries trigger a repair process that can support collagen remodelling. Improvement varies with scar depth, scar type and the skin’s response. A consultation determines suitability and helps set realistic expectations, including whether another approach might be needed alongside or instead of microneedling.

What treatments can help if my acne scars are very deep or raised?

Very deep or raised acne scars may need treatments other than microneedling. Depending on their shape, a physician may consider subcision, targeted scar procedures, laser treatment or specific care for raised scars. These options are not suitable for everyone and are not necessarily available at the clinic. An assessment helps identify an appropriate approach and whether a dermatology referral is needed.

How many microneedling sessions are needed to improve acne scars?

Several sessions are often needed, but the number depends on scar type, depth and how your skin responds. The treatment plan and spacing are determined after an individual assessment. Changes develop gradually because collagen remodelling takes time, and improvement may continue after a session. Photographs taken under consistent conditions can help track progress without implying a guaranteed degree of improvement.

What will my skin look like after microneedling for acne scars?

Your skin may look red and feel tender or mildly swollen after microneedling, with possible dryness or light flaking. The intensity and duration vary with treatment depth and your skin’s response. Follow the aftercare instructions for cleansing, makeup, irritating products and sun protection. Increasing pain, spreading redness, pus or fever should prompt medical advice rather than being assumed to be normal healing.

Is microneedling for acne scars suitable for darker or sensitive skin?

Microneedling may suit some darker or sensitive skin types, but an individual assessment is needed to reduce risks. Pigmentation changes, irritation and, less commonly, new scarring can occur. Mention any history of keloids, cold sores, skin conditions and medicines, including isotretinoin. Active inflammatory acne, infection or significant irritation may mean treatment should be postponed or a different approach considered.
