Key Skincare Ingredients Explained
1. Retinol (Vitamin A)
One of the most researched skincare ingredients. Retinol speeds up cell turnover, boosts collagen, and reduces fine lines, wrinkles, and acne.
- Best for: aging skin, acne, uneven texture
- Use: at night, 2–3x per week to start
- Avoid mixing with: vitamin C, AHAs/BHAs in the same routine

2. Niacinamide (Vitamin B3)
A gentle, versatile ingredient that minimizes pores, evens skin tone, reduces redness, and strengthens the skin barrier.
- Best for: oily skin, large pores, redness, sensitive skin
- Use: morning and/or night
- Pairs well with: hyaluronic acid, zinc, SPF

3. Hyaluronic Acid
A humectant that draws water into the skin, keeping it plump, hydrated, and smooth. Great for all skin types.
- Best for: dry, dehydrated, or dull skin
- Use: morning and night, on damp skin
- Pairs well with: moisturizer, vitamin C, niacinamide
→ Top pick: Neutrogena Hydro Boost Serum — click here
4. Vitamin C
A powerful antioxidant that brightens skin, fades dark spots, and protects against environmental damage.
- Best for: dull skin, hyperpigmentation, early aging
- Use: in the morning before SPF
- Avoid mixing with: retinol in the same routine

5. AHAs & BHAs (Exfoliating Acids)
AHAs (like glycolic acid) exfoliate the surface of the skin. BHAs (like salicylic acid) go deeper into pores, making them ideal for acne-prone skin.
- Best for: acne, clogged pores, uneven texture, dullness
- Use: 2–3x per week, at night
- Avoid mixing with: retinol or vitamin C in the same routine

6. Ceramides
Ceramides are lipids that make up your skin barrier. They lock in moisture and protect against irritation and environmental damage.
- Best for: dry, sensitive, or compromised skin
- Use: morning and night
- Pairs well with: hyaluronic acid, niacinamide
Final Thoughts
You don't need a 10-step routine — you just need the right ingredients for your skin type, used consistently.
