Why You’re Still Struggling with Dark Spots (And What Actually Works)
Hyperpigmentation isn’t just stubborn — it’s strategic. Whether it’s post-acne marks, melasma, or sun-induced discoloration, your skin is fighting to keep the pigment.
And here’s the truth:
Most “brightening serums” don’t do a thing. You need the right exfoliating acid — in the correct strength — layered properly in your routine.
This guide skips the fluff and gives you what dermatologists actually recommend in 2025 to fade dark spots fast.
How Exfoliating Acids Fade Hyperpigmentation (Science-First)
To erase pigment, you need to:
-
Increase skin turnover
-
Inhibit melanin production
-
Lift existing pigment cells
That’s where AHA, BHA, and specialty acids come in. These aren’t scrubs — they’re precision tools that break down discolored skin cells and help your body regenerate fresh, even-toned skin.
The Real Players:
-
Glycolic Acid (AHA): Fastest turnover. Great for acne scars and dull skin.
-
Mandelic Acid (AHA): Gentler, ideal for sensitive or darker skin tones (lower risk of PIH).
-
Salicylic Acid (BHA): Penetrates oil, targets post-inflammatory marks in acne-prone skin.
-
Azelaic Acid: Dual-action: exfoliates + blocks melanin production.
-
Tranexamic Acid: Not a true acid, but a powerhouse for melasma when layered properly.

Pro Routine: How to Layer Acids for Results (Without Wrecking Your Skin)
-
PM routine only. Acids + sun = pigment disaster.
-
Start slow: 2–3x/week max at first.
-
Always moisturize after. Barrier repair is key.
-
NEVER skip sunscreen. One slip ruins weeks of progress.
Example Routine:
-
Cleanser: Non-foaming (CeraVe Hydrating)
-
Exfoliating Acid: 2–3 nights a week, after cleansing
-
Hydration Layer: Hyaluronic Acid or Niacinamide
-
Moisturizer: Ceramide-rich, fragrance-free
-
AM: SPF 50 daily, no excuses
What NOT to Mix With Exfoliating Acids
Avoid these combinations unless guided by a derm:
-
Retinol + AHA/BHA (unless alternate nights)
-
Vitamin C + Acid (can destabilize both)
-
Scrubs + Acids (you’ll destroy your barrier)
When Will You See Results?
Most users see noticeable fading in 6–8 weeks — but only with consistent acid use + daily SPF.
Hyperpigmentation isn’t erased overnight. It’s managed. With the right acid, it can be controlled — and in many cases, erased.
Stop Guessing, Start Targeting
If you’ve been layering random products and not seeing results, it’s time to get tactical.
Exfoliating acids work. But only when you match:
-
the right type of acid
-
to the right type of pigment
-
on the right kind of skin
