How to treat post-inflammatory hyperpigmentation (PIH)
Combination therapy is the most effective treatment for post-inflammatory hyperpigmentation, often involving multiple modalities to achieve significant improvement. For patients with skin of colour or higher Fitzpatrick skin types, we usually begin with barrier repair, acne control, and pigment correctors before adding conservative peels or laser therapy.

FAQ: Post Inflammatory Hyperpigmentation Treatment
Can I treat post inflammatory hyperpigmentation at home without seeing a clinic?
Mild PIH may improve with SPF 50+, gentle skincare, azelaic acid and vitamin C for 3–6 months. Seek assessment if marks are very dark, spreading, linked to uncontrolled acne or not improving.
Is microneedling good or bad for inflammatory pigmentation?
Microneedling can help texture and acne scars, but it may worsen inflammatory pigmentation if performed on active lesions or too aggressively. Pigment-safe topicals, chemical peels and pico lasers are often prioritised first.
Will my PIH come back after laser or peel treatments?
Cleared pigment usually does not return by itself, but new acne, rashes, burns or sunburn can create new post inflammatory hyperpigmentation. Maintenance SPF and acne control are essential.
Are PIH treatments safe during pregnancy or breastfeeding?
Some options, including high-strength retinoids and certain oral medicines, are unsuitable. Azelaic acid and gentle vitamin C may be considered with medical clearance. Always consult your GP, obstetrician and treating clinician.
How do I know if my dark marks are PIH or melasma?
PIH follows previous acne, dermatitis or injury. Melasma is often symmetrical on the cheeks, forehead, upper lip or nose. VISIA Skin Analysis and clinical examination help distinguish pigment conditions so treatment options are chosen safely.
How to Treat Post Inflammatory Hyperpigmentation (PIH): Evidence-Based Options in Adelaide
If you are wondering how to treat post inflammatory hyperpigmentation, the safest answer is rarely one product or one procedure. Treating post-inflammatory hyperpigmentation (PIH) requires a stepwise and multimodal approach, first addressing the underlying cause of inflammation and then using brightening agents, sun protection and, where suitable, in-clinic treatments.
Key Takeaways
- post inflammatory hyperpigmentation is common after acne vulgaris, atopic dermatitis, contact dermatitis, insect bites, cutaneous injuries and cosmetic procedures.
- PIH can take 6–12 months or longer to fade naturally, making targeted treatments essential to speed up the process.
- Daily application of broad-spectrum sunscreen is crucial in managing post-inflammatory hyperpigmentation, as sun exposure can worsen the condition.
- topical agents, chemical peels, pico lasers and laser therapy can produce significant improvement when selected carefully.
- BalaBala Laser Clinic in Adelaide uses VISIA Skin Analysis, PicoSure, Fotona Angel Skin Brightening, full-spectrum lasers and superficial peels to personalise treating pih, especially for pigment-prone skin.
What Is Post Inflammatory Hyperpigmentation (PIH)?
post inflammatory hyperpigmentation describes flat dark patches, tan marks, grey-brown areas or dark brown spots that appear after an inflammatory process. It is also called inflammatory hyperpigmentation, post inflammatory pigmentation, postinflammatory hyperpigmentation, postinflammatory pigmentation or inflammatory pigmentation.
The pathophysiology of postinflammatory hyperpigmentation involves inflammatory mediators stimulating melanocytes to produce excess melanin, which is then transferred to surrounding keratinocytes, leading to epidermal or dermal pigmentation. Epidermal postinflammatory hyperpigmentation occurs when melanin accumulates in the epidermal layers, while dermal postinflammatory hyperpigmentation results from melanin being engulfed by macrophages in the dermis, leading to a more persistent blue-gray pigmentation.
Common clinical features include flat colour change where a pimple, rash or injury healed. PIH differs from acne scars: acne scars change texture, while epidermal pih is mainly colour. However, facial hyperpigmentation and textural acne scars often coexist.
Postinflammatory hyperpigmentation is more common and severe in individuals with darker skin tones, particularly those with Fitzpatrick skin types III to VI, due to increased melanin production in response to skin inflammation or injury. In patients prone to post-inflammatory hyperpigmentation, including those with higher Fitzpatrick skin types, the pigment cell response is stronger, so excess pigment and excess pigmentation can last longer. PIH is medically harmless, but patient education matters because it can strongly affect confidence and quality of life.
How Long Does Post Inflammatory Hyperpigmentation Take to Fade?
Epidermal post inflammatory hyperpigmentation may fade over 6–12 months with excellent sun protection. Deeper pigmentation in the papillary dermis can last several years, particularly in patients with pigment-prone skin.
The timeline depends on:
- depth of pigment: brown epidermal pih fades faster than blue-grey deeper pigmentation;
- skin colour and skin types: darker skin types often hold pigment longer;
- ongoing underlying skin conditions, especially underlying acne;
- UV levels in Adelaide and South Australia.
Without control acne strategies, new inflamed lesions keep creating new marks, so the condition appears “stuck”. Chemical peels and laser therapy are professional interventions that can yield faster results in treating stubborn PIH, often shortening improvement to 3–6 months for mild to moderate cases when combined with topical treatments.
Foundations: Sun Protection and Inflammation Control
Every BalaBala Laser Clinic PIH plan starts with strict UV control and removal of ongoing triggers. Effective treatment of PIH relies on inhibiting pigment production, increasing cell turnover, and preventing further UV damage.
- UV protection: Sun exposure can intensify post-inflammatory hyperpigmentation, making consistent sun protection essential to prevent further darkening of the affected areas. The most critical step in treating PIH is sun protection using broad-spectrum sunscreen, preferably with an SPF of 30 or higher. In Adelaide, we usually recommend daily broad spectrum sunscreen SPF 50+ applied 20 minutes before sun exposure and reapplied every two hours outdoors.
- Better sunscreen choice: Broad-spectrum sunscreens with iron oxides provide superior protection for deeper skin tones since UV light darkens PIH and prolongs healing. Use a daily broad-spectrum sunscreen on cloudy days too.
- Physical protection: wear protective clothing, protective clothing, sunglasses and a wide-brimmed hat, seek shade from 10:00–15:00, and avoid tanning beds.
- Inflammation control: use gentle cleansers, non-comedogenic moisturiser and avoid picking. If acne, eczema or allergic reactions continue, GP or dermatologist care may be needed.
Post-inflammatory hyperpigmentation is more pronounced in individuals with darker skin types, and sun exposure can exacerbate the condition, leading to longer-lasting pigmentation.
Topical Treatments for Post Inflammatory Hyperpigmentation
Topical therapy is first-line. Daily topical treatments for PIH work primarily by blocking melanin production or speeding up the shedding of pigmented skin cells. Apply products from thinnest to thickest consistency to support penetration and skin barrier function.
- Vitamin C: vitamin c, including ascorbic acid, is a potent antioxidant that can interrupt melanin production pathways and help brighten localized dark spots. It also reduces reactive oxygen species and is best used in the morning under SPF.
- Retinoids: topical retinoids such as retinol, retinoic acid, tretinoin and adapalene increase cell turnover, which helps fade dark spots and should be introduced slowly to avoid irritation.
- Other pigment correctors: topical agents such as hydroquinone, kojic acid, retinoids, corticosteroids, and vitamin C are commonly used to treat post-inflammatory hyperpigmentation (PIH). Tyrosinase inhibitors block the enzyme responsible for melanin production, which is crucial in treating PIH. Niacinamide, arbutin, tranexamic acid, licorice extract, green tea and aloe vera may have soothing and melanin-inhibiting properties in addressing PIH.
Exfoliants, including alpha-hydroxy acids (AHAs), help remove dead, pigmented skin cells and can fade discoloration over time. However, to avoid exacerbating PIH, it is important not to use too many strong actives at the same time as they can trigger more irritation. Visible improvement usually begins after 8–12 weeks and builds over 3–6 months.
Chemical Peels for PIH and Acne Scars
chemical peels use formulated acids to remove outer layers affected by hyperpigmentation, refine skin cells and brighten skin tone. Chemical peels, which involve applying formulated chemicals to the skin to remove outer layers affected by hyperpigmentation, can be effective for treating post-inflammatory hyperpigmentation.
Common options include glycolic acid, lactic acid and salicylic acid. salicylic acid is useful when clogged pores and acne are present; glycolic acid can improve dullness and superficial pigment. Superficial peels are usually performed as 3–6 treatments every 2–6 weeks.
In patients with pigment-prone skin, conservative strengths, pigment-suppressing preparation and careful aftercare reduce post-peel inflammatory pigmentation. At BalaBala Laser Clinic, peels may be paired with medical facials or LED to calm inflammation and support skin rejuvenation.
Laser and Light-Based Treatments for Post Inflammatory Hyperpigmentation
Laser treatment is considered when topical therapy and peels are not enough. Laser treatments for post-inflammatory hyperpigmentation include various types such Q-switched Nd:YAG lasers, and picosecond lasers, which are used to target and reduce pigmentation effectively.
pico lasers such as PicoSure and Fotona StarWalker deliver ultra-short pulses to fragment pigment with less heat. Recent advancements in laser technology, such as the use of pico lasers, have shown to be more effective in treating post-inflammatory hyperpigmentation compared to older laser types, clearing pigment faster and with fewer sessions required.
Laser treatments, including Q-switched and picosecond lasers, are utilized to target and reduce post-inflammatory hyperpigmentation, but they should be used cautiously to avoid further irritation. Laser therapy can be effective for treating epidermal post-inflammatory hyperpigmentation, but it may aggravate the condition if not performed carefully, especially in patients prone to post-inflammatory hyperpigmentation. Q-switched, nanosecond and fractional lasers may also improve mixed redness, pigmentation and texture. intense pulsed light can help selected red-brown marks but is less predictable in pigment-prone skin.
Most patients need 3–6 sessions spaced 4–8 weeks apart. Temporary redness, swelling, mild darkening or “peppering” can occur. Strict SPF and no picking are essential after treatment. Research in skin of colour confirms that conservative protocols are critical for safety (systematic review).
Special Considerations for Skin of Colour and Acne Scarring
PIH is often more severe in patients with pigment-prone skin because higher baseline melanin and reactive pigment producing cells respond strongly to acne, waxing, friction, burns and aggressive procedures. Darker skin and higher Fitzpatrick skin types require lower-energy settings, staged treatment and experienced clinicians.
Flat PIH is not the same as acne scarring. Ice-pick, rolling or boxcar scars need texture-focused planning, while pigment needs melanin control. Poorly selected microneedling, deep peels or high-energy lasers can trigger post inflammatory hypopigmentation or a PIH flare.
At BalaBala Laser Clinic, Registered Nurses and medical professionals can also integrate non-invasive anti-ageing technologies such as Ultherapy Prime, Thermage FLX, Ultraformer MPT and EMFACE when patients want lifting, tightening and pigment care in one long-term plan.
Patient Education, Lifestyle and Home Care
A PIH-friendly routine is simple: pH-balanced cleanser, hydrating non-comedogenic moisturiser, morning azelaic acid or vitamin C, night retinoid if tolerated, and SPF 50+. Avoid harsh scrubs, fragrance-heavy products, DIY acids and picking ingrown hairs.
Sleep, antioxidant-rich nutrition, stress control and not smoking support healing. Even with ideal care, treat postinflammatory hyperpigmentation as a months-long process, not a quick fix. Consistency usually beats intensity.
