The best serum for glowing skin depends on your concern. For dullness and uneven tone, Vitamin C serums work well. If you also want hydration and calming benefits, try Powerhouse serum which is our best brightening serum. Look for fragrance-free options suitable for your skin type.

You can apply most face serums once or twice daily, after cleansing and before moisturizer. Antioxidant serums like Vitamin C are great for daytime, while exfoliating or acne serums like salicylic acid or retinol are better suited for nighttime use.

Apply 2–3 drops of serum to clean, slightly damp skin. Gently pat it in with your fingertips, then follow up with a moisturizer to lock everything in. Don’t forget sunscreen in the morning, especially if your serum contains active ingredients like Vitamin C or acids.

There’s no fixed age—start when you notice specific skin concerns like breakouts, dryness, or pigmentation. Teenagers can benefit from niacinamide or salicylic acid, while those in their 20s and beyond may add antioxidants or anti-aging serums like retinol gradually.

It’s generally not recommended to layer too many serums at once—especially if they contain active ingredients. Using several actives together can cause irritation or reduce effectiveness. Stick to one treatment serum at a time for best results. However, some combinations like Vitamin C and Niacinamide can safely be used together, especially in AccuFix formulations that are designed to work synergistically. If you’re using products from different brands, always patch test first.
