Face PIH Brightening System: Your Complete Dark Spot Routine
Step-by-step AM/PM routine for post-acne marks, sun spots, and uneven skin tone
Last Updated: January 16, 2025 | Reviewed by: AMVital Skincare Team
Quick Answer: How to Fade Post-Acne Dark Spots
The best routine for post-acne dark spots (PIH) uses kojic acid in the evening (when skin recovers overnight) and vitamin C in the morning (for antioxidant protection). This multi-active approach inhibits tyrosinase through multiple pathways simultaneously. Use gentle cleanser AM, active kojic acid soap PM with 60-90 seconds contact time, and SPF 30+ daily. Expect texture improvements in 2-4 weeks, visible brightening at 6-8 weeks, and optimal results at 12+ weeks.
Key Definitions
- Post-inflammatory hyperpigmentation (PIH): Dark spots that form after skin trauma (acne, cuts, burns) triggers excess melanin production. PIH is more common and persistent in melanin-rich skin tones.
- Tyrosinase inhibition: Blocking the enzyme that triggers melanin production. Kojic acid achieves ~80% inhibition by chelating copper; curcumin achieves 40-50% through direct enzyme binding. Using both creates multi-pathway blocking.
- Contact time: The 60-90 seconds you leave kojic acid soap on skin before rinsing. This allows the active ingredient to interact with skin's surface layer—rushing reduces effectiveness by 50% or more.

🔬 The Science: How This System Targets Dark Spots
Post-inflammatory hyperpigmentation (PIH) occurs when skin trauma triggers excess melanin production through the tyrosinase enzyme pathway. The Face PIH System attacks dark spots through three simultaneous mechanisms:
- Turmeric's curcumin inhibits tyrosinase activity by 40-50% while suppressing inflammatory cytokines (IL-1, IL-6, TNF-α) that trigger PIH (Vaughn et al., 2016)
- Kojic acid chelates copper ions essential for tyrosinase function, achieving up to 80% enzyme inhibition (Cabanes et al., 1994)
- Vitamin C interrupts melanin synthesis at multiple stages while providing antioxidant protection against UV-induced pigmentation (Pullar et al., 2017)
This multi-pathway approach is more effective than single-ingredient treatments because melanin production has multiple pathways—blocking just one allows others to compensate (Ebanks et al., 2009).

The Face PIH Brightening System is AMVital's complete routine for treating dark spots, post-acne marks, and uneven skin tone on the face. Built on our barrier-first brightening philosophy, this system combines proven brightening actives in a strategic AM/PM routine that delivers visible results in 6-8 weeks—without the irritation that can make hyperpigmentation worse.
Whether you're dealing with stubborn PIH from past breakouts, sun spots from UV exposure, or general unevenness that makes your skin look dull, this system addresses it all through our multi-active approach. Each product plays a specific role, and together they create synergy that single products can't match.

ℹ️ SPF Is Non-Negotiable
Sunscreen is essential for any brightening routine to work. UV exposure triggers melanin production and can undo your brightening progress in a single afternoon. Use SPF 30+ every morning, even on cloudy days. Read more: Why SPF and brightening must go together.
What Is the Best Morning and Evening Routine for Dark Spots?
The best routine uses gentle cleanser + vitamin C serum in the morning (for antioxidant protection) and active kojic acid soap + nourishing oil in the evening (when skin can recover overnight). This strategic timing maximizes results while minimizing irritation. The key is allowing kojic acid soap 60-90 seconds of contact time before rinsing.
🌅 Morning Routine (5 minutes)
🌙 Evening Routine (5-7 minutes)
📅 Weekly Intensive Treatment
2x per week: Use the Turmeric Vitamin C Clay Mask in place of your evening routine. Apply to clean, dry skin. Leave on 10-15 minutes. Rinse, then continue with toner and moisturizer. Best days: Sunday and Wednesday evenings.
💡 Key Takeaway: Strategic Timing Maximizes Results
Use active cleansing (kojic acid soap) in the evening when skin can recover overnight, and antioxidant protection (vitamin C serum) in the morning to defend against daily UV and pollution damage. This timing strategy maximizes brightening while minimizing irritation. The 60-90 second contact time for kojic acid soap is essential—rushing reduces effectiveness.
How Long Does It Take for Dark Spots to Fade?
Dark spots typically show visible fading in 6-8 weeks with consistent daily use. Texture improvements appear in 2-4 weeks, significant brightening at 6-8 weeks, and optimal results for stubborn PIH at 12+ weeks. Newer, lighter spots fade faster than older, deeper pigmentation. Consistency is more important than intensity—daily use outperforms aggressive treatment.

Can I Use Kojic Acid If I Have Sensitive Skin?
Yes, sensitive skin can use kojic acid with proper introduction. Start with every other day use for the first two weeks, then gradually increase to daily. Use a gentle cleanser on non-kojic days, skip clay masks for the first 4 weeks, and always patch test new products first. The turmeric in AMVital's formula provides anti-inflammatory benefits that help buffer potential irritation.
Sensitive Skin Protocol
- Start with Turmeric Kojic Acid Soap every other day, building to daily over 2 weeks
- Use Turmeric Gel Cleanser on non-kojic days
- Skip the clay mask for the first 4 weeks
- Always patch test new products first (patch testing guide)
Oily/Acne-Prone Skin Protocol
For oily or acne-prone skin, kojic acid soap can be used morning AND evening.
- Use Turmeric Kojic Acid Soap morning AND evening
- The clay mask can be used up to 3x weekly
- Skip or use less face oil if it feels too heavy
- The turmeric helps calm active breakouts while fading marks
Dry Skin Protocol
- Use Turmeric Gel Cleanser in the AM (gentler than soap)
- Always follow with toner and cream after kojic soap
- Use face oil generously in the PM
- Add a hydrating serum under the vitamin C serum if needed
Face PIH System: Do's and Don'ts
| ✅ DO | ❌ DON'T |
|---|---|
| Let kojic soap sit on skin 60-90 seconds | Rush through cleansing (reduces effectiveness) |
| Apply SPF every single morning | Skip sunscreen—ever |
| Be consistent for at least 8 weeks | Give up after 2-3 weeks |
| Take progress photos in same lighting monthly | Check for changes daily (too subtle to see) |
| Start slowly if you have sensitive skin | Use all products at full frequency immediately |
| Store vitamin C serum in cool, dark place | Leave products in hot bathroom |
| Hydrate well—drink water, use moisturizer | Over-exfoliate with additional scrubs/acids |

❌ Common Mistake: Adding Too Many Actives
The Face PIH System is already a complete multi-active routine. Adding prescription retinoids, AHAs/BHAs, or other brightening products on top can over-exfoliate and trigger the very inflammation that causes PIH. If you want to incorporate other actives, see our layering guide or consult a dermatologist.
