When choosing a serum, the features you should look for really depend on your skin goals, but here are some important general factors to consider: Key Active Ingredients Look for ingredients that match your needs: 1.Vitamin C: Brightening, antioxidant protection. 2.Hyaluronic Acid: Hydration and plumping. 3.Niacinamide: Reduces redness, minimizes pores, strengthens skin barrier. 4.Retinol: Anti-aging, acne treatment. 5.Peptides: Firming and repairing. 6.AHA/BHA (like glycolic or salicylic acid): Exfoliation, clearing breakouts. Concentration of Actives The strength matters. Higher concentrations work faster but may irritate sensitive skin. Beginners often do better with lower percentages. Formulation and Texture Lightweight and fast-absorbing serums are ideal. For oily skin: opt for water-based serums. For dry skin: thicker, slightly oil-based serums can help. Stability and Packaging Sensitive ingredients like Vitamin C and Retinol need air-tight, dark packaging to stay potent. Avoid transparent bottles for sensitive actives. Fragrance-Free and Non-Irritating Especially if you have sensitive or acne-prone skin, choose serums without added fragrance, alcohol, or harsh preservatives. Compatibility with Your Routine Make sure the serum complements your cleanser, moisturizer, and any actives you're already using (some combinations, like Vitamin C + Retinol, can be too harsh together if not balanced carefully).
