Hyperpigmentation is one of the most common skin complaints, cropping up as dark patches, sunspots, or post-acne marks. While it’s completely harmless, many people find it knocks their confidence—especially when it’s stubborn, spreads, or keeps coming back.
But what actually causes hyperpigmentation? And more importantly, how can you treat it safely & effectively?
Let’s dive into how skin pigmentation works, the various forms it can take, and the most effective ways to treat it so your skin can look its best.
🧬 What Is Hyperpigmentation?
Hyperpigmentation is a condition where certain areas of the skin become darker than the surrounding skin. This happens due to an overproduction of melanin—the pigment that gives skin, hair, and eyes their colour.
While melanin helps protect your skin from sun damage, too much of it in one spot can lead to visible discolouration.
It can appear as:
- Freckles
- Sunspots
- Acne marks
- Large patches of darker skin
- Post-inflammatory marks after rashes, cuts, or eczema
🔍 Types of Hyperpigmentation
Understanding the specific type of pigmentation you’re dealing with is key to choosing the right treatment.
1. Post-Inflammatory Hyperpigmentation (PIH)
This type appears after the skin has been inflamed or injured. Common triggers include:
- Acne breakouts
- Cuts or grazes
- Eczema or psoriasis
- Aggressive cosmetic treatments
More common in darker skin tones, PIH often fades with time—but it can take months without intervention.
2. Melasma
Often hormonally driven, melasma usually appears as symmetric patches on the cheeks, forehead, upper lip or jawline. It’s commonly linked to:
- Pregnancy (nicknamed “the mask of pregnancy”)
- Hormonal contraception
- Menopause or hormone therapy
- Sun exposure (a major trigger)
It’s more stubborn than other forms & requires long-term management.
3. Sunspots (Solar Lentigines)
These flat, brown patches appear on areas frequently exposed to the sun, like your face, hands, chest, and shoulders. They’re caused by prolonged sun exposure and tend to become more common as you age, which is why they’re often called age spots.
4. Freckles
Genetic and sun-sensitive, freckles aren’t a sign of damage—but they do darken with sun exposure. Some people embrace them; others choose to lighten them for a more even complexion.
☀️ Common Causes of Hyperpigmentation
1. UV Radiation
The sun is the biggest contributor to hyperpigmentation. Even short periods of exposure without SPF can:
- Trigger melasma
- Darken PIH & sunspots
- Cause new pigmentation to develop
Daily sunscreen use is essential—not just in summer.
2. Hormonal Changes
Fluctuating hormone levels (especially oestrogen & progesterone) can increase melanin production, especially in people with a genetic predisposition.
This is why melasma is often linked to:
- Pregnancy
- Birth control pills
- Hormone therapy
- Thyroid dysfunction
3. Inflammation & Skin Trauma
Any time the skin is injured or inflamed, melanin production ramps up to protect the area—sometimes leading to dark patches that outstay their welcome.
Triggers include:
- Acne picking
- Rashes
- Over-exfoliation
- Cosmetic procedures without proper aftercare
4. Medication Side Effects
Some medications increase skin sensitivity or alter pigmentation pathways:
- Chemotherapy drugs
- Antimalarials
- Antibiotics (like tetracyclines)
- Hormone treatments
If pigmentation develops while on medication, speak with a healthcare provider before starting any aesthetic treatment.
🎯 How to Treat Hyperpigmentation
Hyperpigmentation can be challenging to treat—but with the right approach, it’s entirely manageable. The key is combining professional treatments with long-term skincare and sun protection.
🔬 In-Clinic Treatments That Work
1. Chemical Peels
Peels use acids to exfoliate the top layers of skin & reduce the appearance of pigment. They also encourage cell turnover, revealing brighter skin underneath.
Best for:
- Post-acne marks
- Sunspots
- Early melasma
Mild peels include glycolic, lactic, and mandelic acid; deeper peels use TCA or Jessner’s solution.
2. Microneedling
Microneedling creates microchannels in the skin, triggering collagen production and improving both tone and texture. It also helps skincare products penetrate deeper.
Best for:
- PIH
- Acne scarring
- Skin of colour (lower risk than lasers)
3. LED Light Therapy
Red light therapy can calm inflammation & boost healing—especially useful for sensitive skin with post-acne marks. Often used alongside other treatments.
4. Laser Pigmentation Removal
Lasers like Q-switched Nd:YAG or fractional CO2 can break down deeper pigment deposits. These are best used under expert guidance, especially for melasma or darker skin tones.
Caution: Incorrect laser use can worsen pigmentation—always choose an experienced practitioner familiar with your skin type.
🧴 At-Home Ingredients That Help
Topical skincare plays a big role in fading and preventing pigmentation; look for ingredients with a proven track record:
✅ Effective Brightening Agents:
- Vitamin C – antioxidant that inhibits melanin production and brightens tone
- Niacinamide – reduces inflammation & limits pigment transfer
- Azelaic acid – great for acne-related marks and redness
- Retinoids – boost cell turnover, and fade discolouration
- Tranexamic acid – useful for melasma and stubborn dark patches
- Kojic acid – inhibits melanin formation (often used in clinic-grade products)
Patience is key—visible improvements may take 8–12 weeks of consistent use.
🧯 Prevention: Your Best Weapon
Once hyperpigmentation starts to fade, your next mission is keeping it gone. These simple habits make all the difference:
☀️ Wear Sunscreen. Religiously.
- Use SPF 30+ every day—even in winter or indoors
- Reapply every 2 hours if outside
- Choose broad-spectrum to block UVA and UVB
🖐 Avoid Picking & Over-Treating
- Don’t pop pimples or scratch rashes
- Avoid harsh scrubs or overuse of exfoliating acids
- Give your skin time to recover between treatments
💧 Keep Skin Barrier Healthy
- Use moisturisers with ceramides or hyaluronic acid
- Avoid drying cleansers and hot water
- A strong skin barrier = less inflammation = less risk of PIH
🌰 In a Nutshell
| Type of Hyperpigmentation | Most Effective Treatments |
| PIH (post-acne marks) | Microneedling, peels, niacinamide |
| Melasma | Tranexamic acid, peels, LED therapy |
| Sunspots | Peels, lasers, vitamin C |
| Freckles/dull tone | Exfoliation, SPF, brightening serums |
Hyperpigmentation isn’t one-size-fits-all, and treating it often takes a tailored approach based on your skin tone, lifestyle, and the root cause of the pigment. But with the right tools & guidance, you can absolutely restore clarity, evenness, and confidence to your skin.
