Hyperpigmentation is one of the most common skin concerns, affecting people of all skin types and ages. Whether it’s sunspots, melasma, or post-acne marks, dark spots can make the skin look uneven and dull. The good news? There are effective treatments that can help fade pigmentation and restore a bright, even complexion. Dr Tom Goyer, a skincare expert in Sydney, explains the causes of hyperpigmentation and the best ways to treat and prevent it.
What Is Hyperpigmentation?
Hyperpigmentation occurs when melanin, the pigment that gives skin its color, is overproduced in certain areas, leading to dark patches or spots.
Types of Hyperpigmentation:
- Sunspots (Lentigines): Caused by long-term sun exposure, appearing as brown spots on the face, hands, and shoulders.
- Melasma: Often triggered by hormonal changes (e.g., pregnancy, birth control), it appears as brown patches on the forehead, cheeks, and upper lip.
- Post-Inflammatory Hyperpigmentation (PIH): Dark marks left behind after acne, eczema, or an injury.
Tip: Identifying the type of hyperpigmentation is the first step to finding the right treatment!
What Causes Hyperpigmentation?
Several factors can lead to excess melanin production:
- Sun Exposure: The #1 cause of hyperpigmentation. UV rays trigger melanin production, leading to dark spots over time.
- Hormonal Changes: Fluctuations in estrogen and progesterone (pregnancy, birth control, menopause) can worsen pigmentation.
- Skin Trauma: Acne, cuts, burns, and eczema can leave behind dark marks (PIH) as the skin heals.
- Genetics: Some people are more prone to pigmentation due to their genetic makeup.
Tip: Sunscreen is non-negotiable if you want to treat and prevent dark spots!
How to Treat Hyperpigmentation
The best approach combines topical treatments, professional procedures, and sun protection.
1. Topical Treatments for Hyperpigmentation
Certain skincare ingredients can fade dark spots and prevent new ones from forming:
- Vitamin C: A powerful antioxidant that brightens skin and inhibits melanin production.
- Retinoids (Retinol, Tretinoin): Increase cell turnover, helping to fade dark spots faster.
- Niacinamide (Vitamin B3): Reduces inflammation and prevents excess pigmentation.
- Alpha Arbutin: A gentle skin-lightening agent that fades pigmentation over time.
- Hydroquinone (Prescription Only): A potent lightening agent for stubborn hyperpigmentation.
- Azelaic Acid: Great for acne-prone skin, reducing redness and dark spots.
Tip: Layering Vitamin C in the morning and retinol at night can maximise results!
2. Exfoliation to Remove Pigmented Cells
Exfoliation speeds up cell renewal, helping to fade dark spots faster:
- AHAs (Glycolic & Lactic Acid): Dissolve dead skin cells and boost radiance.
- BHAs (Salicylic Acid): Penetrate deep into pores, reducing post-acne marks.
- Enzyme Exfoliants: A gentle alternative for sensitive skin.
Tip: Start exfoliating 2-3 times a week to avoid irritation.
3. Professional Treatments for Hyperpigmentation
For stubborn pigmentation, dermatologist-approved procedures can provide faster results:
- Chemical Peels: Use acids to exfoliate and fade pigmentation over several sessions.
- Laser Therapy: Targets melanin clusters, breaking down pigmentation.
- Microneedling: Stimulates collagen production to reduce dark spots and scars.
- Intense Pulsed Light (IPL): Uses light energy to target sunspots and redness.
Tip: Always consult a professional to find the best treatment for your skin type.
How to Prevent Hyperpigmentation
1. Wear Sunscreen Daily
Sun exposure is the biggest culprit behind hyperpigmentation, so SPF is essential!
- Best Sunscreen: SPF 30 or higher, broad-spectrum (UVA & UVB protection).
- Reapplication: Every 2 hours if outdoors.
- Bonus Protection: Wear hats & sunglasses for extra defense.
Tip: A tinted sunscreen with iron oxides can provide even better protection against pigmentation!
2. Avoid Picking at Your Skin
Touching, squeesing, or scratching blemishes leads to post-inflammatory hyperpigmentation (PIH).
Tip: Use pimple patches to prevent picking!
3. Maintain a Skincare Routine
A consistent routine with brightening ingredients will keep pigmentation at bay:
- AM Routine: Cleanser → Vitamin C → Moisturiser → Sunscreen
- PM Routine: Cleanser → Retinol or AHA/BHA → Moisturiser
Tip: Stick to gentle formulas to avoid irritation, which can worsen pigmentation.
When to See a Dermatologist
If your hyperpigmentation isn’t improving with skincare, it may be time for professional treatments.
Signs You Should See a Doctor:
- Dark spots aren’t fading after 3-6 months of consistent treatment.
- Pigmentation spreads or worsens despite sun protection.
- You develop sudden or unusual dark patches.
Tip: A dermatologist can create a customised treatment plan to tackle stubborn hyperpigmentation.
Hyperpigmentation can be frustrating, but with the right treatments, skincare ingredients, and sun protection, you can achieve a brighter, more even complexion. Consistency is key—results take time, but a combination of Vitamin C, retinoids, exfoliation, and SPF will help fade dark spots.
