Hyperpigmentation — the overproduction of melanin causing darkened patches or spots on the skin — is one of the most common dermatological concerns worldwide. From sun spots and melasma to post-inflammatory hyperpigmentation (PIH), these conditions can significantly impact confidence and quality of life. Modern aesthetic medicine offers multiple effective treatments, but choosing the right approach depends on the type, depth, and cause of the pigmentation.
At Axiom Aesthetics, we take a systematic approach to hyperpigmentation treatment, combining clinical assessment with evidence-based treatment protocols. This guide covers the main types, their causes, and the most effective treatments available.
Types of Hyperpigmentation
| Type | Appearance | Common Causes | Location | Treatment Difficulty |
|---|---|---|---|---|
| Solar lentigines (sun spots) | Flat, well-defined brown spots | Cumulative UV exposure | Face, hands, chest, shoulders | Moderate — responds well to treatment |
| Melasma | Larger, diffuse brown-grey patches | Hormones, UV, genetics | Cheeks, forehead, upper lip, jawline | Difficult — chronic, recurrence-prone |
| Post-inflammatory hyperpigmentation (PIH) | Darkened marks at sites of previous inflammation | Acne, eczema, injury, procedures | Anywhere — follows the inflammatory site | Moderate — usually resolves with treatment |
| Freckles (ephelides) | Small, light brown spots | Genetic + UV | Face, arms, chest | Easy — responds well to laser/IPL |
| Café-au-lait spots | Flat, uniformly light brown patches | Congenital | Anywhere | Moderate — may recur after treatment |
Treatment Options
1. Topical Treatments (First-Line)
- Hydroquinone (2–4%): The gold standard prescription skin lightener. Inhibits tyrosinase enzyme. Use for 3–6 month courses with breaks to prevent ochronosis. Available on prescription in the UK
- Azelaic acid (15–20%): Inhibits tyrosinase and reduces melanocyte hyperactivity. Safe in pregnancy. Effective for melasma and PIH
- Vitamin C (10–20%): Inhibits melanin production and provides antioxidant protection. Gradual brightening over 8–12 weeks
- Retinoids (tretinoin 0.025–0.1%): Accelerate cell turnover, dispersing melanin from the epidermis more rapidly. Essential component of melasma management
- Niacinamide (5–10%): Inhibits melanosome transfer from melanocytes to keratinocytes. Gentle and well-tolerated
- Tranexamic acid (topical 2–5% or oral 250mg twice daily): Emerging treatment for melasma with growing evidence. Inhibits plasminogen activation in melanocytes
- Cysteamine (5%): Naturally occurring antioxidant that inhibits melanin synthesis. Newer treatment with promising clinical data
2. Chemical Peels
Chemical peels exfoliate pigmented skin and stimulate cell turnover, bringing fresh, less pigmented skin to the surface.
- Glycolic acid (30–70%): Effective for superficial pigmentation. Course of 4–6 peels, 2–4 weeks apart
- Modified Jessner’s peel: Combination acid peel effective for melasma and PIH
- Mandelic acid: Safer for darker skin types due to lower PIH risk
- TCA (10–20%): Medium-depth peel for more resistant pigmentation
Cost: £100–£350 per session.
3. IPL (Intense Pulsed Light)
IPL targets melanin with broad-spectrum light, fragmenting pigment that is then cleared by the body. Highly effective for solar lentigines and freckles. Requires caution in melasma (can worsen if settings are too aggressive).
Sessions: 2–4. Cost: £150–£400 per session.
4. Laser Treatments
- Q-switched Nd:YAG (1064nm): Low-fluence settings (“laser toning”) for melasma. 6–10 sessions, 1–2 weeks apart. Controversial — some studies show good results, others show no benefit or worsening
- Picosecond laser: Ultra-short pulse duration shatters pigment particles more effectively than nanosecond lasers. Promising for resistant pigmentation. £200–£500 per session
- Fractional laser (non-ablative): Creates micro-columns of injury that promote pigment clearance during healing. Useful for PIH combined with texture improvement
5. Microneedling With Brightening Serums
Microneedling enhances the penetration of topical brightening agents (vitamin C, tranexamic acid, niacinamide) whilst stimulating dermal remodelling. Particularly effective for PIH and mild melasma.
Sessions: 3–6, 4 weeks apart. Cost: £200–£400 per session.
Expert Insight
“Melasma is the most challenging form of hyperpigmentation to treat because it is driven by hormonal factors that cannot be fully controlled. We always set realistic expectations: treatment can significantly improve melasma but requires long-term management rather than a one-off cure. The cornerstone of melasma management is aggressive sun protection, prescription-strength topicals, and cautious in-clinic treatments. Aggressive laser or IPL can actually worsen melasma by triggering rebound pigmentation.”

Treatment Approach by Pigmentation Type
| Pigmentation Type | First-Line Treatment | Second-Line Treatment | Maintenance |
|---|---|---|---|
| Sun spots | IPL or picosecond laser | Chemical peels + retinoid | SPF 50 + vitamin C daily |
| Melasma | Topical combination (hydroquinone + tretinoin + azelaic acid) + SPF 50 | Gentle peels, tranexamic acid, low-fluence laser | Lifelong SPF, maintenance topicals, avoid triggers |
| PIH | Topical brighteners (vitamin C, niacinamide, azelaic acid) | Chemical peels, microneedling | Treat underlying condition, SPF |
| Freckles | IPL or laser | Chemical peel | SPF to prevent recurrence |
The Critical Role of Sun Protection
No pigmentation treatment will produce lasting results without rigorous sun protection. UV exposure stimulates melanocytes, triggering pigment production that undoes treatment progress. Essential steps:
- SPF 50 broad-spectrum sunscreen daily — mineral (zinc oxide, titanium dioxide) preferred for melasma as it provides immediate, broad protection
- Reapply every 2 hours during outdoor activities
- Wear a wide-brimmed hat and seek shade during peak UV hours (11am–3pm)
- Consider iron oxide-containing sunscreen — visible light (particularly from screens) can worsen melasma; iron oxide blocks visible light
- Tinted mineral sunscreen provides visible light protection plus cosmetic coverage
Frequently Asked Questions
Can hyperpigmentation be permanently cured?
For sun spots and PIH, yes — treatment can permanently remove existing pigmentation. However, new spots can develop with continued sun exposure. Freckles often return with sun exposure after treatment. Melasma is a chronic condition that requires ongoing management; while it can be greatly improved, it tends to recur with hormonal changes, sun exposure, or heat. Long-term maintenance with SPF, topical treatments, and periodic in-clinic sessions is essential for sustained results.
Is laser treatment safe for dark skin?
Some laser treatments carry a higher risk of complications (PIH, burns, scarring) in darker skin types (Fitzpatrick IV–VI). However, specific wavelengths and settings are safe and effective when used by experienced practitioners. The Nd:YAG laser (1064nm) has a longer wavelength that bypasses melanin in the epidermis, making it safer for darker skin. Picosecond lasers also show a good safety profile. The key is choosing a practitioner experienced in treating diverse skin types. At Axiom Aesthetics, we tailor all treatments to the individual’s skin type and colour.
How long does it take to see results from pigmentation treatment?
Topical treatments typically require 8–12 weeks of consistent use for visible improvement. Chemical peels show progressive improvement over a course of 4–6 sessions. IPL and laser can produce noticeable lightening after 1–2 sessions, with full results at 4–8 weeks. Melasma responds more slowly and may require 3–6 months of multimodal treatment. Patience is essential — rushing treatment with aggressive settings can cause rebound pigmentation, particularly with melasma.
What causes melasma to flare up?
Common melasma triggers include: UV exposure (the most significant trigger), hormonal changes (pregnancy, oral contraceptives, HRT), heat exposure (saunas, hot yoga, hot climates), visible light (screen exposure), certain medications, and stress. Some patients notice flares with specific skincare products. Identifying and avoiding your personal triggers, combined with rigorous sun protection, is essential for long-term management. Keep a trigger diary to track patterns. Book a consultation for personalised melasma management.
Can I treat hyperpigmentation at home?
Yes, many effective treatments are available for home use. A basic hyperpigmentation routine includes: vitamin C serum (10–20%) in the morning, niacinamide serum (5–10%), SPF 50 mineral sunscreen, and a retinoid in the evening (start with retinol 0.3–0.5%, building to 1% or prescription tretinoin). Azelaic acid (10% OTC or 15–20% prescription) is an excellent addition. Over-the-counter alpha arbutin and kojic acid can also help. However, for stubborn or severe hyperpigmentation, professional treatments significantly accelerate improvement. Contact us for a personalised brightening plan.
