How to Treat Hyperpigmentation

Understanding Hyperpigmentation: Sun Damage vs. Post-Acne Marks
(And How Reform Skincare Can Help)

Hyperpigmentation is one of the most common skin concerns worldwide. Whether you’re dealing with stubborn sun spots that won’t fade, or the marks left behind after a breakout finally heals, that uneven tone can be frustrating and hard to cover.

The good news: once you understand what kind of hyperpigmentation you have, you can choose the right ingredients and products—and see much better results over time.

Below, we’ll break down the difference between sun-induced hyperpigmentation and post-acne marks, then show how carefully chosen treatments (including options from REFORM Skincare) can fit into an effective routine.

What Is Hyperpigmentation?

Hyperpigmentation is an umbrella term for any area of the skin that becomes darker than your natural skin tone. This happens when melanocytes (the cells that produce melanin pigment) are triggered to make more pigment than usual or distribute it unevenly.

Common triggers include:

• UV and visible light exposure
• Inflammation (from acne, eczema, picking, or irritation)
• Hormonal changes (e.g., melasma)
• Certain medications or procedures

Two of the most frequent forms people struggle with are:

1. Sun damage (sun spots, age spots, solar lentigines)
2. Post-inflammatory hyperpigmentation (PIH) from acne

They can look similar at a glance, but they behave differently and often need slightly different strategies.

Sun Damage Hyperpigmentation: What It Looks Like

Sun-induced hyperpigmentation is driven mainly by long-term exposure to UV rays and visible light. Over time, this leads to:

• Flat brown or dark spots (often called sun spots or age spots)
• Freckle-like clusters on cheeks, nose, shoulders, and hands
• A generally uneven, dull, “sun-damaged” appearance

These are more common in people with a history of a lot of sun exposure and can appear or worsen as you get older.

Why Sunscreen Alone Isn’t Always Enough

UV protection is essential, but research increasingly shows that visible light—especially high energy visible light (HEVL)—also worsens pigmentation in many skin tones, particularly Fitzpatrick skin types III–V.

This is where tinted, mineral-based sunscreens can be especially powerful. The iron oxides in tint help block HEVL, which is important if you’re prone to dark spots, melasma, or stubborn hyperpigmentation.

REFORM Skincare options to consider for sun-related hyperpigmentation:

• SPF 50+ Tinted Sunscreen 

  

   

  • A broad-spectrum mineral sunscreen with tint (containing iron oxides) to help protect against both UV and visible light.
  • Especially useful for those with medium to deeper skin tones or anyone prone to melasma and dark spots, since visible light can trigger excess melanin.
    
    

• SPF 50+ Antioxidant Sunscreen
  

  
  • Broad-spectrum protection plus antioxidants to neutralise free radicals generated by UV exposure.
  • Ideal for daily use if you’re targeting both pigmentation and premature ageing.
    
    

• SPF 30 Mineral Sunscreen
  
  

  
  • A mineral-based formula suitable for sensitive or reactive skin, offering solid everyday protection to prevent existing dark spots from worsening.

Daily sunscreen is non-negotiable if you care about hyperpigmentation. Any treatment—no matter how strong—will underperform if new UV and visible light damage is happening every day.

Post-Acne Marks: Post-Inflammatory Hyperpigmentation (PIH)

While sun spots come from chronic UV exposure, post-acne marks are usually post-inflammatory hyperpigmentation (PIH).

When you get a breakout, your skin becomes inflamed. In response, melanocytes can overproduce pigment in that area. Once the pimple heals, you’re left with:

• Flat brown marks (on lighter skin)
• Brown, dark brown, or even greyish marks (on medium to deeper skin tones)
• Occasionally reddish or purplish marks in early stages

These are not scars in the classic sense (they’re not raised or indented), but they can linger for months—especially if:

• You picked or squeezed the pimple
• You have a higher Fitzpatrick type (more melanin in the skin)
• You don’t wear sunscreen consistently

PIH responds well to a combination of exfoliants, pigment-suppressing actives, antioxidants, and strict UV/visible light protection.

Core Ingredients That Help Fade Hyperpigmentation

Whether your dark marks are from the sun or from acne, certain ingredients are proven to help:

1. Vitamin C (L-ascorbic acid)

   • Potent antioxidant
   • Supports collagen
   • Helps brighten skin and reduce the look of dark spots
   • Best used in well-formulated serums
     
     

2. Retinoids (like retinol)

   • Increase cell turnover
   • Help fade uneven tone over time
   • Improve texture and fine lines as a bonus
     
     

3. Exfoliating acids (AHA/BHA)

   • Glycolic acid (AHA): Helps lift pigmented, dull surface cells
   • Salicylic acid (BHA): Great for acne-prone skin; clears pores and can reduce the chance of new PIH
     
     

4. Hydrating and barrier-supportive ingredients

   • Ingredients like hyaluronic acid, vitamin B5, and nourishing moisturisers help keep the skin barrier strong, which reduces irritation and makes active treatments more tolerable.

How Reform Skincare Fits Into a Hyperpigmentation-Focused Routine

REFORM Skincare blends evidence-based actives with a medical-science approach, which makes it well-suited for targeted concerns like pigmentation and post-acne marks.

Here’s how you can build a structured routine using key products from the range.

1. Cleanse: Prep the Skin Without Stripping

For most skin types concerned with pigmentation, choose a gentle but effective cleanser:

• Glycolic Acid Foaming Cleanser

  • Contains glycolic acid, an AHA that helps exfoliate the surface of the skin.
  • Suitable if you have resilient or combination/oily skin and want a mild daily exfoliating effect.
    
    

• Salicylic Acid Foaming Cleanser

  • Best for oily, acne-prone skin.
  • Helps keep pores clear, reducing new breakouts (and therefore new PIH).
    
    

• Gentle Hydrating Crème Cleanser

  • A great choice if your skin is sensitive, dry, or easily irritated by acids.
  • Keeps your barrier comfortable—crucial when you’re using brightening actives like vitamin C and retinol.

2. Treat: Target Pigmentation With Serums

This is where you focus on fading hyperpigmentation and evening skin tone.

• Vitamin C 20% Serum

  • High-strength 20% vitamin C to help brighten, fight free radicals, and reduce the appearance of dark spots.
  • Best used in the morning, under sunscreen.
  • Particularly helpful for sun damage and dull, uneven tone.
    
    

• HYAL • Vitamin C + E Serum

  • Combines hydration (hyaluronic-type actives) with vitamins C and E, offering brightening plus antioxidant and hydrating benefits.
  • Ideal if you want vitamin C but also need an extra moisture boost and support for your barrier.
    
    

• Vitamin B5 Gel

  • Soothing and hydrating, with vitamin B5 to support skin repair and calm irritation.
  • Excellent as a supporting serum if your routine includes strong actives like acids or retinol, helping to minimise irritation that can itself lead to more PIH.

For post-acne marks, pairing a gentle exfoliating cleanser (like Salicylic Acid Foaming Cleanser if you’re acne-prone) with a vitamin C serum and strong sun protection is often a powerful combination.

3. Night-Time Renewal: Retinol and Resurfacing

Night is the best time to use more potent renewal-focused actives.

• Retinol 1% Creme

  • A high-strength retinol designed to support skin renewal, improve texture, and reduce the look of fine lines and pigmentation.
  • Especially helpful for both sun-induced pigmentation and post-acne marks, as increased cell turnover gradually lifts uneven tone.
  • Start slowly: 1–2 nights per week, then build up as tolerated to reduce dryness or irritation.
    
    

• Resurface Routine | Mild Scarring + Texture

  • This curated routine is designed for those dealing with mild scarring and textural issues.
  • Often, acne doesn’t just leave colour changes—it can leave subtle unevenness in texture. This set complements PIH treatments by smoothing the surface of the skin alongside brightening.

When using retinol or resurfacing products, it’s vital to:

• Avoid over-exfoliation
• Moisturise well
• Be extremely consistent with daily SPF

4. Moisturise: Support the Skin Barrier

Actives only work well if your barrier is healthy.

• Everyday Moisturiser

  • Light, suitable for normal to combination skin.
  • Good daytime option over serums, under sunscreen.
    
    

• Intensive Moisturiser

  • Richer, ideal for dry or compromised skin, or during colder weather.
  • Pairs well with retinol or after exfoliating products to avoid over-drying.
    
    

• Skin Barrier Repair Cream

  • Specifically designed to support barrier function.
  • Valuable if your skin is easily irritated, red, or reactive—which can worsen PIH if not controlled.

If you’re using strong actives for pigmentation (like retinol and high-strength vitamin C), a barrier-focused product like Skin Barrier Repair Cream can make the difference between a routine that works and one that causes setback-inducing irritation.

5. SPF Every Morning: Non-Negotiable

As mentioned earlier, daily sun protection is the foundation of any pigmentation routine.

From REFORM Skincare, consider:

• SPF 50+ Tinted Sunscreen – excellent for pigmentation-prone skin, thanks to mineral filters and tint with iron oxides to help protect against UV and HEVL (visible light).
• SPF 50+ Antioxidant Sunscreen – for strong SPF plus antioxidant support.
• SPF 30 Mineral Sunscreen – for a more minimal daily option, especially for sensitive or reactive skin.

Apply generously as the last step of your morning routine and reapply during prolonged sun exposure.

Putting It All Together: Example Routine

Here’s how a simple, hyperpigmentation-focused routine using REFORM Skincare might look:

Morning

1. Cleanse:

   • Gentle Hydrating Crème Cleanser or Glycolic Acid Foaming Cleanser (if your skin tolerates acids)
     
     

2. Treat:

   • Vitamin C 20% Serum or HYAL • Vitamin C + E Serum
     
     

3. Hydrate (optional, if needed):

   • Vitamin B5 Gel
     
     

4. Moisturise:

   • Everyday Moisturiser
     
     

5. Protect:

   • SPF 50+ Tinted Sunscreen or SPF 50+ Antioxidant Sunscreen

Evening

1. Cleanse:

   • Salicylic Acid Foaming Cleanser (if acne-prone) or Gentle Hydrating Crème Cleanser
     
     

2. Treat (2–3 nights per week to start):

   • Retinol 1% Creme
     
     

3. Repair & Moisturise:

   • Skin Barrier Repair Cream or Intensive Moisturiser

On nights when you’re not using retinol, you can focus on hydration (e.g., Vitamin B5 Gel + moisturiser) to support recovery.

For more complex concerns—like a mix of acne, PIH, and texture issues—consider complete sets like Pigmentation Solution, Oily, Acne Prone Skin | Complete Routine, or Resurface Routine | Mild Scarring + Texture, which bundle compatible products into a structured regimen.

How Long Until You See Results?

With consistent use of brightening actives, retinoids, and strict sun protection, many people notice:

• A more even, brighter tone in 4–8 weeks
• Visible fading of recent post-acne marks within 8–12 weeks
• Gradual softening of longer-standing sun spots over several months

Progress is rarely overnight. Hyperpigmentation is slow to appear—and slow to leave. Staying consistent with:

• A gentle but active routine
• Daily SPF (ideally with HEVL protection)
• A strong skin barrier

is what leads to real, lasting change.

Final Thoughts

Understanding whether your hyperpigmentation comes mainly from sun damage or post-acne marks helps you choose the right strategy:

• Sun damage: Focus on antioxidants (especially vitamin C), retinoids at night, and rigorous UV + visible light protection with high-quality sunscreens like REFORM’s SPF 50+ Tinted or SPF 50+ Antioxidant Sunscreen.
• Post-acne marks (PIH): Combine gentle exfoliation, targeted brightening serums (like Vitamin C 20% Serum), acne-appropriate cleansers, and consistent SPF to prevent new marks from forming.

By layering evidence-based ingredients in a structured routine and protecting your skin daily, you’ll steadily move toward clearer, more even-toned skin—whether your dark spots started with the sun, a breakout, or a bit of both.
