Hyperpigmentation: Why It Happens and How to Treat It
Hyperpigmentation occurs when areas of the skin produce excess melanin, resulting in spots or patches that appear darker than the surrounding skin. With Scottsdale’s abundant sunshine, UV exposure can contribute to existing discoloration and make some forms of hyperpigmentation more noticeable, so understanding why dark spots develop can help you take a more informed approach to managing them.

What Is Hyperpigmentation?
What Is Hyperpigmentation?
Hyperpigmentation is a common skin condition that occurs when certain areas of the skin produce more melanin than surrounding skin, causing flat spots or patches to appear darker. These areas can range in color from light brown to dark brown or gray, depending on your skin tone and the underlying cause. A systematic review found that approximately 89% of post-inflammatory hyperpigmentation cases were triggered by inflammatory skin conditions, while 83% occurred on the face.
At a glance
- Hyperpigmentation is caused by excess melanin production.
- It may appear as small spots or larger patches of discoloration.
- Sun exposure is one of the most common contributing factors.
- It can develop after acne, skin irritation, or injury.
- Many forms of hyperpigmentation can improve with consistent skincare and professional treatments.
What Causes Hyperpigmentation?
What Causes Hyperpigmentation?
Hyperpigmentation can develop for several different reasons, but it always involves an increase in melanin production. Identifying what's causing the discoloration can help determine which skincare products, daily habits, or professional treatments may be most appropriate.
Sun Exposure
Ultraviolet (UV) rays stimulate melanin production as part of the skin's natural defense against sun damage. Research suggests that up to 80% of visible facial skin aging is caused by chronic UV exposure rather than intrinsic aging alone, highlighting why daily sunscreen use is one of the most effective ways to help prevent sun spots and uneven pigmentation.
Post-Inflammatory Hyperpigmentation (PIH)
After the skin experiences inflammation from acne, eczema, cuts, burns, or other injuries, it may produce excess melanin as it heals, leaving behind dark marks.
Hormonal Changes
Hormonal fluctuations during pregnancy, while taking birth control, or from other hormonal changes can contribute to melasma, a common form of hyperpigmentation.
Aging
Years of cumulative sun exposure and natural changes in the skin can make age spots and uneven pigmentation more noticeable over time.
Genetics & Skin Tone
Some people are naturally more prone to developing certain types of hyperpigmentation. Individuals with medium to deeper skin tones are also more likely to experience post-inflammatory hyperpigmentation after skin irritation. Nearly 15% of adults report PIH, making it one of the most frequently reported pigmentary disorders worldwide.
Types of Hyperpigmentation
Understanding the Different Types of Hyperpigmentation
Not all discoloration is the same. Identifying the type of hyperpigmentation you're experiencing can help you better understand what may be causing it and which skincare approaches or professional treatments may be most appropriate.
Sun Spots (Solar Lentigines)
Often called age spots or liver spots, these flat brown spots develop after years of cumulative sun exposure. They're most common on the face, hands, shoulders, and other frequently sun-exposed areas.
Freckles
Freckles are small pigmented spots that are largely influenced by genetics. They often become darker with sun exposure and lighter during seasons with less UV exposure.
General Uneven Skin Tone
Some people experience diffuse discoloration rather than distinct spots. This uneven pigmentation may result from cumulative sun exposure, aging, environmental factors, or previous skin irritation.
Post-Inflammatory Hyperpigmentation (PIH)
These dark marks develop after the skin heals from acne, cuts, burns, insect bites, or other forms of inflammation. Unlike scars, they are changes in pigment rather than skin texture.
Melasma
Melasma appears as larger, symmetrical patches of discoloration, typically on the cheeks, forehead, nose, or upper lip, and it affects approximately 11% of adults. Hormonal changes and sun exposure are common contributing factors.
Everyday habits
Daily Habits That Support Even Skin Tone
Do
- Wear broad-spectrum SPF 30+ sunscreen every day.
- Reapply sunscreen when spending time outdoors.
- Wear hats or seek shade during peak sun hours.
- Use skincare products consistently.
- Treat acne and skin irritation early.
- Moisturize regularly to support your skin barrier.
Avoid
- Picking at pimples or scabs.
- Skipping sunscreen on cloudy days.
- Using harsh scrubs that irritate the skin.
- Over-exfoliating.
- Trying too many new products at once.
Ingredients to know
Skincare Ingredients That May Help Improve Hyperpigmentation
Some skincare ingredients focus on slowing excess pigment production, while others encourage skin cell turnover to gradually improve the appearance of discoloration. Many treatment plans combine several ingredients to address hyperpigmentation from different angles.
| Ingredient | Helps with | Best for | Notes |
|---|---|---|---|
| Vitamin C | Brightening skin | Sun spots | Antioxidant that helps even skin tone |
| Retinoids | Skin renewal | Uneven tone | Encourages cell turnover |
| Niacinamide | Uneven tone | Sensitive skin | Helps support the skin barrier |
| Azelaic Acid | Dark spots | Post-acne marks | Gentle and well tolerated |
| Tranexamic Acid | Melasma | Stubborn discoloration | Often paired with other ingredients |
No single ingredient works for every type of hyperpigmentation. Consistency, daily sun protection, and choosing products appropriate for your skin type are often just as important as the ingredients themselves.
Why Dark Spots?
Why Dark Spots Sometimes Stick Around
Hyperpigmentation often improves gradually, but it rarely disappears overnight. Even effective skincare products may take several weeks or months to produce noticeable changes, and some types of discoloration are naturally more resistant to treatment.
It may be worth speaking with a skincare professional if you:
- Feel like your progress has stalled.
- Have uneven skin tone that’s affecting your confidence.
- Have dark spots that have remained for months.
- Want a treatment plan that’s tailored to your skin.
- Continue developing new discoloration.
A consultation doesn’t always mean professional procedures are necessary. Sometimes identifying the underlying cause and making a few adjustments to your skincare routine can help support better long-term results.
Professional treatments
Professional Treatments That May Help Improve Hyperpigmentation
While skincare products can play an important role in managing discoloration, professional treatments often target pigmentation more effectively by accelerating skin renewal or improving the appearance of damaged skin. Your provider may recommend one treatment or a combination of treatments depending on your skin's needs.
Chemical Peels
May help with
- Sun damage
- Dark spots
- Uneven pigmentation
Chemical peels exfoliate the skin in a controlled manner, encouraging healthier skin cells to replace damaged ones. Different peel strengths can be selected based on your skin type and treatment goals.
Microneedling
May help with
- Post-inflammatory pigmentation
- Skin texture
- Fine lines
Microneedling creates controlled micro-injuries that stimulate collagen production and skin renewal, making it a popular option for improving both discoloration and overall skin quality.
Professional Facials
May help with
- Dull skin
- Mild discoloration
- Skin maintenance
Professional facials can help remove surface buildup, support healthy skin turnover, and enhance the appearance of overall skin radiance. They are often incorporated into ongoing skincare routines to help maintain results.
Helping Prevent Hyperpigmentation
Helping Prevent Hyperpigmentation
While it's not always possible to prevent hyperpigmentation, there are several steps you can take to help reduce the risk of developing new dark spots and keep existing discoloration from becoming more noticeable.
Wear Sunscreen Every Day
Ultraviolet (UV) exposure is one of the most common triggers of hyperpigmentation. Applying a broad-spectrum sunscreen with SPF 30 or higher every day can help protect your skin and prevent existing dark spots from becoming darker.
Avoid Picking or Scratching Your Skin
Picking at acne, insect bites, scabs, or other skin irritations can increase inflammation, making post-inflammatory hyperpigmentation more likely.
Treat Skin Concerns Early
Managing acne, eczema, and other inflammatory skin conditions promptly may help reduce the likelihood of lingering discoloration after the skin heals.
Be Patient and Consistent
Hyperpigmentation usually fades gradually. Following a consistent skincare routine and protecting your skin from the sun can help support long-term improvement.
