You should apply treatments before moisturizer—especially if they’re serums, exfoliants, or active ingredients like:

• Vitamin C

• Hyaluronic acid

• Niacinamide

• Retinol

• AHAs/BHAs (glycolic, salicylic acid)

---

🌟 Why before moisturizer?

• Moisturizers create a barrier that can block active treatments from absorbing effectively.

• Treatments work best when applied to clean, dry (or slightly damp) skin so they can penetrate deeper.

---

🔁 Exception: Spot treatments with strong actives

• Some acne spot treatments (like benzoyl peroxide or sulfur) may be better after moisturizer to reduce irritation—this is called the “moisturizer sandwich” method.

🧴 General layering order:

1. Cleanser

2. (Optional: toner)

3. Treatment/serum (like vitamin C, retinol, acids)

4. Moisturizer

5. Sunscreen (AM only)
