Hyperpigmentation, Dark Spots & Uneven Skin Tone
Two people can have what appears to be the same dark spot, yet the factors driving it may be completely different.
Some marks appear after a breakout heals. Others develop gradually after years of sun exposure. Melasma may flare during pregnancy, hormonal changes or even despite doing "all the right things".
Understanding what type of pigmentation you're dealing with can help explain why certain treatments work beautifully for some people but deliver disappointing results for others.
Why Do My Dark Spots Keep Coming Back?
Pigmentation can look like it has faded, but the triggers behind it may still be active.
Managing pigmentation isn't only about finding a stronger brightening treatment. It's also about reducing the triggers that keep reactivating it.
Which Type Sounds Most Familiar?
Melasma
Large, patchy areas of pigmentation that commonly appear on the cheeks, forehead, upper lip and jawline.
Usually linked to:
Hormonal fluctuations • UV exposure • Visible light
Post-Inflammatory Hyperpigmentation
Dark marks that remain after inflammation has settled, often following acne, irritation or certain cosmetic procedures.
Usually linked to:
Acne • Skin injury • Irritation
Sun Spots
Small, well-defined spots that develop gradually over time, particularly on areas exposed to sunlight.
Usually linked to:
Cumulative UV exposure
What People Often Miss
Melasma Isn't Just A Sun Problem
Hormones and visible light may also influence melasma, making it more complex than many people realise.
Heat May Matter Too
Some people notice pigmentation becoming more noticeable during periods of prolonged heat exposure.
Acne Marks Often Outlast The Breakout
For many people, the dark mark becomes more frustrating than the original spot itself.
Tinted Protection Can Play An Important Role
For pigmentation-prone skin, visible light may matter too. Tinted sunscreens containing iron oxides can help provide protection against both UV and visible light exposure.
The key is applying enough product to achieve the level of protection stated on the label.
Ingredients That Help Support Uneven Skin Tone
Tranexamic Acid
Helps improve the appearance of melasma and uneven skin tone.
Diglucosyl Gallic Acid
Targets multiple pathways involved in pigmentation while remaining microbiome-friendly.
Niacinamide
Helps improve uneven-looking skin tone while supporting the skin barrier.
White Tomato Extract
Helps defend against UV-induced oxidative stress while supporting brighter-looking skin.
Magnesium Ascorbyl Phosphate
A stable Vitamin C derivative that provides antioxidant support while helping improve skin radiance.
So What Should You Focus On?
1. Wear sunscreen daily and apply enough to achieve the protection stated on the label.
2. Choose brightening ingredients suited to the type of pigmentation you're experiencing.
3. Minimise triggers that may be relevant to you, whether that's UV exposure, visible light or inflammation.
4. Be patient. Pigmentation rarely fades overnight, and consistency matters more than intensity.

Frequently Asked Questions
Why do my dark spots keep coming back?
Even after pigmentation improves, triggers such as UV exposure, visible light, hormonal fluctuations and inflammation can reactivate pigment-producing cells. This is why pigmentation often requires ongoing maintenance rather than a one-time fix.
How do I know if I have melasma or post-acne marks?
Melasma often appears as larger, patchy areas of pigmentation that tend to occur symmetrically on the face. Post-inflammatory hyperpigmentation usually develops after a breakout, irritation or injury to the skin.
Can acne marks fade on their own?
Many post-inflammatory marks improve gradually over time. However, the timeline varies depending on the depth of pigmentation, your skin tone and how consistently you protect your skin from further triggers.
Can heat worsen pigmentation?
Some people notice pigmentation becoming more noticeable during periods of prolonged heat exposure. This may include hot weather, saunas and intense exercise, although individual experiences can vary.
Do I still need sunscreen if I'm using brightening products?
Yes. Brightening ingredients help improve the appearance of existing pigmentation, while sunscreen helps reduce the triggers that contribute to the formation of new dark spots.
How much sunscreen should I apply?
For the face and neck, around two finger lengths of sunscreen are generally recommended to achieve the SPF level tested in the laboratory. Applying too little may reduce the level of protection you receive.
How long does pigmentation take to fade?
There isn't a universal timeline. Some post-acne marks may improve within weeks, while more persistent forms of pigmentation such as melasma can take several months to gradually improve.
