Post-Acne Pigmentation (PIH)

PIH happens when inflammation from acne triggers excess melanin production during healing. The result is dark marks that can remain long after the breakout clears. PIH is common in inflammatory acne and in skin that has been irritated or over-treated.

PIH can fade naturally, but it often takes several months depending on depth, skin tone, inflammation levels and UV exposure. Many clients choose structured treatment because PIH can remain visible for a long time without intervention.

Yes, but the approach must be sequenced correctly. Aggressive exfoliation can worsen inflammation and trigger further pigmentation. ULANDA uses barrier-safe correction to improve tone while protecting skin stability.

UV exposure stimulates melanin production and can darken PIH significantly. Sun exposure is one of the most common reasons PIH persists longer than expected.

Yes. Picking, squeezing and skin trauma increases inflammation and deepens pigment activation. This often leads to darker marks that take longer to clear.

Yes. Overuse of strong acne products can damage the barrier, trigger irritation and increase inflammation — which can worsen both breakouts and pigmentation marks. This is why acne and pigmentation must be treated together.

It can be highly effective when the skin is stable enough. Microneedling supports skin renewal and pigment correction, but it must be sequenced properly and not introduced during active inflammation.

PIH is triggered by inflammation (such as acne), while general hyperpigmentation may be UV-driven or age-related. The treatment approach differs because PIH often requires inflammation control alongside pigment correction.

Yes. PIH can look similar to melasma, but melasma is hormonally reactive and often symmetrical. ULANDA assesses pigment type carefully to ensure the correct pathway is chosen.

Yes. Even small acne marks can create patchy uneven tone across the face. Many clients feel their skin looks "unclear" even when acne is no longer active, which is why PIH correction is a key part of tone restoration.

ULANDA is a nurse-led skin clinic in Ware, Hertfordshire offering structured Advanced Skin Health Consultations and programme-led treatment pathways. Many clients travel from Hertford, Hoddesdon, Broxbourne, Bishop's Stortford, Cheshunt and St Albans for safe, clinically guided treatment and long-term skin stability.
