✅ How to safely use multiple serums:
-
Apply from thinnest to thickest texture
-
Watery → gel → creamy
-
This helps absorption and prevents pilling
-
-
Target different concerns
-
Example:
-
Morning: Vitamin C (brightening) + Hyaluronic Acid (hydrating)
-
Night: Niacinamide (oil control) + Retinol (anti-aging)
-
-
-
Limit to 2–3 serums at a time
-
Too many actives can overwhelm or irritate your skin
-
-
Patch test when adding new serums
-
Especially if you’re using ingredients like acids or retinoids
-
⚠️ Serums you should not mix directly:
| Avoid Mixing | Why |
|---|---|
| Vitamin C + Niacinamide | Can cancel each other out (modern formulas are more stable, but still tricky) |
| Retinol + AHAs/BHAs | Can over-exfoliate and irritate |
| Vitamin C + Retinol | Can cause sensitivity, better to use at different times of day |
💡 Pro tip:
Try layering no more than 2 active serums in one routine, and alternate others on different days or times (AM vs PM).
