Best Hyperpigmentation Treatment in NZ (Evidence-Based Guide)
Hyperpigmentation is one of the most common skin concerns worldwide, causing uneven tone and dark patches on the face and body. It can result from sun exposure, acne, hormonal changes, heredity, and inflammation. Hyperpigmentation is often caused by a combination of factors rather than a single trigger. The most effective treatment not only focuses on fading existing pigment but also on identifying and avoiding the triggers that cause it to worsen or return. This guide explains which hyperpigmentation treatments work best, based on clinical research and dermatology guidelines.
What Is Hyperpigmentation and Why Treatment Depends on the Cause
Hyperpigmentation occurs when the skin produces excess melanin, the pigment responsible for skin colour. This overproduction can be triggered by ultraviolet (UV) radiation, inflammation from acne or injury, hormonal changes such as pregnancy, or certain medications. Treating pigmentation successfully involves both fading existing pigment and preventing its return. This includes daily sun protection and reducing known triggers. For example, melasma related to hormonal contraception may improve when the pill is discontinued, while acne-related pigmentation is more likely to fade when breakouts are treated gently and picking or squeezing is avoided.
How Hyperpigmentation Develops in the Skin
What causes excess melanin production
Melanin is produced by specialised skin cells called melanocytes in response to stimuli such as UV light or inflammation. When melanin production becomes uneven, pigment accumulates in the upper or deeper layers of the skin, creating visible dark patches. Once this process begins, darker areas absorb more UV radiation than surrounding skin — similar to how a black car heats up faster in the sun than a white one. This creates a vicious cycle in which existing pigmentation becomes darker and more difficult to fade. For this reason, sun protection is a top priority in the treatment of hyperpigmentation.
Sun exposure and pigmentation
UV radiation stimulates melanocytes to increase melanin production as a protective response. In high-UV environments like New Zealand, sun exposure is one of the most significant contributors to the development of pigmentation disorders and the recurrence of melasma and dark spots.
In reality, it is almost impossible to completely avoid sun exposure in New Zealand, but your skin will benefit from minimising it as much as possible. Sun exposure does not only occur at the beach — it also happens while driving, walking, jogging, cycling, and even indoors near windows. For this reason, daily sunscreen use is essential. Applying sunscreen every morning is the most important step, and reapplication later in the day is ideal when practical. In real life, consistent once-daily use is often what people manage, and this can still provide significant protection.
If your skin becomes sunburnt, pigmentation treatment should be paused. Sunburn is an inflammatory injury, and treating hyperpigmentation before the inflammation has settled can worsen pigment changes. Instead, focus first on calming the skin using soothing ingredients such as calendula, aloe vera, or zinc oxide. Zinc oxide–based sunscreens are my favourites because they provide physical UV protection while also offering anti-inflammatory benefits, making them useful for both prevention and skin recovery.
Hormonal pigmentation (melasma)
Melasma is strongly associated with oestrogen and progesterone fluctuations during pregnancy or contraceptive use. These hormones and their synthetic versions especially in The pill and menopause HRT, sensitise melanocytes to UV light, making sun exposure a major trigger.
Post-inflammatory hyperpigmentation (acne marks)
Inflammation from acne, eczema, burns, or cosmetic procedures can cause melanocytes in the affected area to overproduce pigment, leaving dark marks after healing. It can also be triggered by bad nutrition, Mosquito bites, and of course, the sun. Almost anything can trigger PIH, and sometimes you will not even know where it came from.
Medical Treatments for Hyperpigmentation
Hydroquinone for Hyperpigmentation
Hydroquinone is considered the gold standard topical treatment for hyperpigmentation. It works by inhibiting tyrosinase, an enzyme essential for melanin synthesis. Clinical trials have shown hydroquinone to be highly effective in the short term for melasma and post-inflammatory pigmentation, sometimes used in combination with retinoids and mild corticosteroids (triple combination therapy).
Long-term use is not recommended due to risks of irritation and rare ochronosis.

Hydroquinone is classified as a prescription medicine in New Zealand. Products sold without medical authorisation are unregulated and pose a risk of adverse skin reactions
Azelaic Acid as an Alternative to Hydroquinone
Azelaic acid inhibits melanin synthesis and reduces inflammation. It has been shown to be comparable to hydroquinone for melasma in some studies, with fewer side effects. It is also beneficial for acne-prone skin, making it useful for post-inflammatory hyperpigmentation.
Over the counter, no prescription needed in New Zealand.
Sun protection is needed to avoid adverse effects.
In any case of redness, stop using and soothe the skin.
Retinoids and Combination Prescription Creams
Retinoids such as tretinoin increase cell turnover, helping remove pigmented keratinocytes and allowing penetration of other actives. Combination therapies including hydroquinone, tretinoin, and corticosteroids remain among the most popular regimens in dermatology literature.
As always, Sun protection is needed to avoid adverse effects.
In any case of redness, stop using and soothe the skin.
Tranexamic Acid for Melasma and Dark Patches
Tranexamic acid is originally a medicine used to reduce bleeding in certain medical conditions. Skin lightening is a side effect rather than its original purpose. While this effect has led to its use in treating melasma and other pigmentation disorders, it is not without risk. Tranexamic acid can cause systemic side effects, and its use for pigmentation should only be considered under medical supervision. Some clinicians prescribe it because treatment options for stubborn melasma are limited. Personally, I wouldn’t take the risk, definitely not the oral form.
Natural and Non-Prescription Treatments for Hyperpigmentation
Vitamin C for Dark Spots
Vitamin C (ascorbic acid) reduces melanin formation and provides antioxidant protection from UV damage. While it is less potent than prescription agents, it can improve brightness and support other treatments.
Niacinamide and Pigment Transfer Reduction
Niacinamide reduces the transfer of melanosomes from melanocytes to keratinocytes, decreasing visible pigmentation. Studies show it improves uneven tone with regular use and is considered well-tolerated.
It can cause skin irritation, so be cautious.
I tried it, it was like magic at first, but within a week I was red as a tomato:)
Sun protection is essential.
Kojic Acid and Licorice Root Extract
Kojic acid inhibits tyrosinase, while licorice extract (glabridin) reduces melanocyte activity and inflammation. These ingredients are commonly found in brightening creams and soaps.
I never tried this one, but from what I read, irritation may occur; proceed with caution and lots of sunscreen.
Botanical and Herbal Brightening Ingredients
Arbutin, mulberry, bearberry, and green tea extracts have shown pigment-reducing properties in small clinical studies, though results vary depending on formulation and stability. Fading might be very subtle, but still considered a success in a clinical trial.
Professional Treatments for Hyperpigmentation
Procedures mostly:
➡ remove what’s already there
➡ but don’t stop new pigment from forming
➡ Increase inflammation
➡ High risk of rebound effect, especially for darker skin owners. (I mean, anything darker than Donald Trump!)
➡ These treatments are expensive, and you may think you’ll get rid of pigmentation forever. This is not true.
➡ Until now, we played it safe, proceeding with extreme caution
Chemical Peels for Pigmentation
Glycolic acid, salicylic acid, and lactic acid peels accelerate exfoliation and reduce surface pigment. They are most effective when combined with topical treatments.
I do not recommend peelings at all for pigmentation, not even sugar scrubs. I think it irritates the skin and increases inflammation, which is the last thing you want when treating hyperpigmentation.
But
If you insist, and you have severe pigmentation, I recommend my hyperpigmentation products any time. I know I’m biased, but I made these products because I needed them. I made the mistake of deep peeling, Hydroquinone, and many more that I want to save you from going through.
Severe pigmentation is mild pigmentation treated badly.
If you go for it and want to do deep peeling, do it under a dermatologist’s supervision and understand that this is just a jumpstart, you’ll have to preserve the results with extremely strict sun protection andsoothing the skin. After the skin is healed and not red anymore, you can start using my hyperpigmentation cream at night or any of the options above, always paying attention to any redness and calming it.
Laser and Light-Based Treatments
Lasers target melanin directly but must be selected carefully, especially in darker skin tones, as improper settings can worsen pigmentation.
I would only recommend laser for age spots in very white people, like coffee marks on the hands or face, created from sun exposure over the years.
Microneedling for Hyperpigmentation
I tried this, very painful, but it did nothing for my pigmentation or for my skin in general. If you’ve benefited from this, please let me know. I think it’s a hype, not much research either.
