Hyperpigmentation is one of the most common skin concerns, but not all dark spots are the same. Two of the most frequent causes are melasma and sun damage hyperpigmentation . While both appear as darkened areas of skin, they have different triggers, patterns, and ideal treatment approaches. Understanding the difference is key to choosing the right products and achieving visible results.
At Dehaz Skincare , we specialize in professional, results-driven formulations powered by natural oils, butters, botanicals, and advanced actives. Our approach focuses on brightening, correcting discoloration, and strengthening the skin barrier without irritation or downtime .
What Is Melasma?
Melasma is a type of hyperpigmentation often triggered by hormonal changes (such as pregnancy, birth control, or thyroid imbalance), UV exposure, and heat. It usually appears as symmetrical, patchy dark areas on the cheeks, forehead, nose, or upper lip.
Tends to affect women more than men.
Deep-rooted and chronic — often requires consistent care.
Triggers include hormones, UV light, and even blue light exposure.
Treatment Goals for Melasma:
Gently reduce pigment activity without overstimulating the skin.
Calm and balance skin to reduce flare-ups.
Prevent recurrence with barrier-strengthening, antioxidant-rich skincare.
What Is Sun Damage Hyperpigmentation?
Sun damage hyperpigmentation (also called sunspots, age spots, or solar lentigines) is caused by years of UV exposure. Unlike melasma, these spots are usually isolated and not hormone-driven. They often show up on areas with the most sun exposure — face, chest, shoulders, and hands.
Appear as brown or dark spots, usually in older skin.
Caused primarily by UV radiation.
Can be lightened effectively with exfoliation and antioxidant treatments.
Treatment Goals for Sun Damage:
Break down excess pigment and accelerate cell renewal.
Infuse antioxidants to repair and protect skin from further UV damage.
Restore hydration and elasticity for overall rejuvenation.

Why SPF 50 Is Non-Negotiable in Hyperpigmentation Care
Whether you’re dealing with melasma or sun-induced hyperpigmentation, one truth remains: no skincare product will work if you’re not wearing sunscreen every single day.
Here’s why SPF 50 broad-spectrum protection is essential:
Prevents New Pigmentation: UV exposure triggers melanin production, deepening existing spots and creating new ones.
Stops Worsening of Melasma: Even a few minutes of sun without SPF can undo weeks of progress in fading pigmentation.
Boosts Effectiveness of Treatments: Brightening actives like kojic acid, niacinamide, and tranexamic acid work better when the skin isn’t under constant UV stress.
Prevents Post-Treatment Setbacks: Professional treatments like enzyme masks or resurfacing peels make the skin more sensitive to UV — SPF 50 is your shield against rebound pigmentation.
Protects from Blue Light & Infrared Damage: Modern SPF formulas also guard against light emitted from screens, which can worsen pigmentation in melasma-prone skin.
In short: SPF 50 is your most powerful anti-hyperpigmentation product. Think of it as the foundation that allows your brightening serums, oils, and masks to actually do their job.
Key Takeaways
Melasma is hormonally driven and worsens with UV and heat exposure — it requires gentle, consistent treatment.
Sun damage hyperpigmentation comes from cumulative UV exposure and responds well to antioxidants and resurfacing treatments.
SPF 50 every day is the most important step in preventing and managing both conditions. Without sunscreen, even the best treatments won’t deliver results.
Dehaz Skincare offers professional treatments and daily care that combine plant-based ingredients, antioxidant oils, and gentle enzymes — delivering visible brightening with zero downtime .
Final Thoughts
When it comes to hyperpigmentation — whether melasma or sun damage — consistency, patience, and protection are everything. By pairing daily SPF 50 protection with gentle but effective Dehaz treatments , you can support brighter, more even, and healthier-looking skin over time.

Why is SPF 50 important when treating hyperpigmentation or melasma?
A: SPF 50 offers a high level of sun protection, blocking about 98% of harmful UVB rays. This is essential for people with hyperpigmentation and melasma, as UV exposure is one of the main triggers for dark spots and uneven skin tone. Daily use prevents further pigmentation from forming and allows treatments (like brightening serums or peels) to work more effectively.
What causes hyperpigmentation and melasma?
A: Hyperpigmentation and melasma are caused by the overproduction of melanin, the pigment that gives skin its color. Triggers include sun exposure, hormonal changes (like pregnancy or birth control), genetics, inflammation (from acne or skin injury), and certain medications.
Why does sun exposure make pigmentation worse?
A: UV rays stimulate melanocytes (pigment-producing cells) to create more melanin as a defense mechanism. For those prone to melasma or dark spots, even minimal sun exposure can worsen discoloration, leading to darker, more stubborn patches.
Can lifestyle factors influence hyperpigmentation?
A: Yes. Stress, poor sleep, unbalanced diet, and smoking can aggravate pigmentation by causing inflammation and oxidative stress in the skin. Protecting your skin also means supporting your overall health.
What’s the difference between melasma and other types of hyperpigmentation?
A: Melasma usually appears as symmetrical, brownish patches on the face and is strongly linked to hormonal changes and UV exposure. Other hyperpigmentation types include post-inflammatory hyperpigmentation (after acne or skin injury) and sunspots (caused by long-term UV damage).
What skincare ingredients are best for treating hyperpigmentation?
A: Key ingredients include vitamin C, niacinamide, azelaic acid, hydroquinone (prescription), kojic acid, arbutin, glycolic acid, and retinoids. These work by reducing melanin production, speeding up cell turnover, and brightening the skin.
Why is SPF 50 specifically recommended for hyperpigmentation?
A: SPF 50 blocks about 98% of UVB rays, offering stronger protection than lower SPFs. For people with melasma or dark spots, this higher level of defense prevents worsening pigmentation and supports treatment results.
Is melasma curable or only manageable?
A: Melasma is considered a chronic skin condition that can be managed but not always permanently cured. Consistent sun protection, skincare treatments, and sometimes lifestyle changes help keep it under control.
How long does it take to see improvement in pigmentation with consistent care?
A: With daily SPF 50 and targeted treatments, improvement can usually be seen within 8–12 weeks. However, results vary depending on the severity of pigmentation and consistency of the skincare routine.

What are hyperpigmentation & melasma?
Hyperpigmentation is the umbrella term for darkened areas of skin caused by excess melanin. Melasma is a chronic, often symmetrical pattern of brown or gray-brown patches that typically appears on the cheeks, forehead, upper lip, and chin. It’s driven by a combination of UV exposure, hormonal changes (pregnancy, oral contraceptives), genetics, and inflammation from acne or skin injury.
While melasma can wax and wane, it’s highly sun-sensitive. The goal isn’t a one-time “cure,” but a strategy that prevents new pigment, gently fades existing spots, and maintains results.
Quick take: Sunscreen doesn’t erase spots, but without it, every brightening treatment you use works against a constant stream of UV-triggered pigment.
Core triggers to control
UV radiation (UVA/UVB): The #1 driver. UVA penetrates windows and clouds; UVB burns. Both stimulate pigment production.
Visible/blue light (HEV): Can contribute to pigment in deeper skin tones; iron oxides in tinted sunscreens help.
Hormonal shifts: Pregnancy, HRT, and some contraceptives can intensify melasma.
Inflammation: Breakouts, picking, harsh scrubs, or hot wax can lead to post-inflammatory hyperpigmentation (PIH).
Heat: Saunas, hot yoga, and overheating can flare melasma even without sun.
Why SPF 50 matters for pigmentation-prone skin
SPF measures protection against UVB; a well-formulated SPF 50 blocks ~98% of UVB. For pigment-prone skin, that extra edge versus SPF 30 is meaningful because even small UV “leaks” can darken patches or trigger rebound.
Broad-spectrum is non‑negotiable
Choose a product clearly labeled broad‑spectrum so you’re covered for UVA as well. If you spend time near windows or devices, consider a tinted sunscreen with iron oxides to help against visible light.
Daily + all environments
Wear SPF 50 every day, indoors and out. UVA passes through glass, and incidental exposure (commute, quick errands, desk near a window) adds up.
How to apply & reapply correctly
Amount: Use two finger lengths for face and neck (≈ 1/3 tsp). Don’t forget ears, hairline, and jaw.
Timing: Apply as the last step of your morning routine, 15 minutes before sun exposure.
Reapplication: Every 2–3 hours outdoors; sooner if sweating, swimming, or toweling off. Indoors near windows: reapply at least once midday.
Over makeup: Use sunscreen sticks, mists, or mineral powder SPF for convenient top-ups.
Pro tip: Keep a reapplication product in your bag or at your desk so “I forgot” stops being a thing.
Mineral vs chemical sunscreens
Mineral (zinc oxide, titanium dioxide) formulas sit on the skin and deflect/absorb UV. They’re often gentler for sensitive or melasma‑prone skin and less likely to sting. Chemical filters (like Tinosorb, Uvinul, avobenzone, octisalate) absorb UV and can feel lighter and more elegant under makeup. Both work—choose the one you’ll wear generously and reapply.
Tinted options & deeper skin tones
Tinted mineral SPFs with iron oxides can mitigate blue light effects and avoid a white cast, making them a strong choice for deeper complexions and melasma on the upper lip or cheeks.
Complete AM/PM routine for fading & prevention
AM (protect & brighten)
Cleanser: Gentle, low‑pH.
Antioxidant serum: Vitamin C (L‑ascorbic acid or derivatives) to brighten and support collagen.
Support actives: Niacinamide (2–5%) for tone and barrier; azelaic acid (10–15%) for redness and pigment control.
Moisturizer: Lightweight, non‑irritating.
Sunscreen: Broad‑spectrum SPF 50. Consider tinted for blue‑light defense.
PM (correct & renew)
Cleanser: Double cleanse if wearing heavy SPF/makeup.
Exfoliation (2–3×/week): Glycolic, lactic, or mandelic acid—avoid over‑exfoliating.
Targeted actives: Retinoids for cell turnover; kojic acid, arbutin, or prescription hydroquinone (short cycles under medical guidance).
Moisturizer: Barrier‑supportive with ceramides and cholesterol.
Sensitive? Start actives on alternate nights and add a bland moisturizer sandwich to minimize irritation—and therefore PIH risk.
Professional treatments (always with strict SPF)
Dermatology options can accelerate results but require impeccable photoprotection to avoid rebound.
Chemical peels: Superficial AHA/BHA or Jessner’s for texture and tone. Space sessions and pause if irritation flares.
Microneedling: Can improve texture and help topical penetration; pair with pigment‑safe protocols.
Lasers/light devices: Must be chosen carefully for melasma; conservative settings and experienced providers are critical.
Rule of thumb: The stronger the procedure, the stricter the sunscreen routine needs to be.
Lifestyle & diet that support skin evenness
Heat management: Limit saunas, hot yoga; cool the skin post‑workout.
Anti‑inflammatory diet: Colorful produce (vitamins C & E), omega‑3s, green tea; steady hydration.
Sleep & stress: Prioritize consistent sleep and stress strategies to reduce inflammatory cascades.
Hands off: Don’t pick acne or scabs; spot‑treat calmly to avoid PIH.
Common mistakes to avoid
Using SPF only on sunny days or skipping reapplication.
Over‑exfoliating, leading to irritation and darker spots.
Relying on makeup SPF alone—layers are too thin to protect.
Stopping treatment as soon as spots fade instead of maintaining.
Ignoring neck, ears, and hairline where pigment can linger.
Frequently Asked Questions
What causes hyperpigmentation and melasma?
Overactive melanocytes create excess melanin, triggered by UV exposure, hormones, genetics, inflammation (like acne), and sometimes medications. Melasma is a chronic, sun‑sensitive pattern that often appears symmetrically on the face.
Why does sun exposure make pigmentation worse?
UVA and UVB stimulate melanin as a defense. Even small “incidental” exposure darkens existing patches and can spark new ones, which is why daily SPF 50 is foundational.
Is SPF 30 enough, or do I need SPF 50?
SPF 30 is good, but SPF 50 offers a tighter safety margin for pigment‑prone skin. That extra protection helps prevent darkening and supports better long‑term outcomes.
Do I need sunscreen indoors?
Yes. UVA penetrates windows and clouds. Wear SPF 50 daily and consider a tinted product for added visible‑light defense.
Which is better for melasma: mineral or chemical sunscreen?
Both work when broad‑spectrum and SPF 50. Mineral (zinc/titanium) is often preferred for sensitive skin and can be paired with tints to avoid white cast and help with HEV light.
How often should I reapply SPF?
Every 2–3 hours outdoors or sooner with sweat/swim/toweling. Indoors near windows, reapply at least once midday. Use sticks, mists, or powder SPFs over makeup.
What skincare ingredients help fade dark spots?
Vitamin C, niacinamide, azelaic acid, kojic acid, arbutin, retinoids, and gentle AHAs (like glycolic/mandelic). Prescription hydroquinone can be used in short, supervised cycles.
What professional treatments are safe for pigmentation?
Superficial peels, microneedling, and select lasers/settings with experienced providers. Strict sunscreen use is essential to avoid rebound pigment.
Can lifestyle changes make a difference?
Yes—manage heat, reduce skin irritation, eat an antioxidant‑rich diet, and protect sleep. Less inflammation equals fewer triggers for pigment.
How long until I see results?
With daily SPF 50 and targeted actives, many see improvement in 8–12 weeks. Maintain your routine to prevent relapse.
The Wild Orchid Repair Serum is by far the most beautiful serum. I use it during my face massage with clients and they always purchase it at the end of their facial. Their initial response is "Wow, what is that? It smells amazing!". You don't need a lot for the full effect. It can be used day or night but I always recommend at night, when you are sleeping and your skin repairs itself.
This moisturizer is perfect for oily skin. It provides the perfect amount of hydration without feeling to heavy, thick or greasy. It control oil production and gives the skin necessary ingredient to balance moisture. It has an earthy scent from the oak moss which is nice too. It pairs well with SPF.
