The Ordinary Serum Favorites Set vs e.l.f. Pure Skin Back to Basics Mini Kit

These are different kinds of purchase. The Ordinary set is two full-size treatment serums, Hyaluronic Acid 2% + B5 and Niacinamide 10% + Zinc 1%, aimed at people who already have a cleanser and moisturizer and want to target hydration and blemishes. The e.l.f. kit is a three-step routine in travel sizes: cleanser, toner and moisturizer built on oat milk, aloe and niacinamide, and it suits sensitive skin and beginners. Reviewers rate the Ordinary serums highly and say they plump skin, but warn they need damp skin and can feel drying in cold, dry air; the e.l.f. kit is gentler and more complete but smaller and less concentrated.

• Choose the Ordinary Serum Favorites Set if you already have a cleanser and moisturizer and want full-size serums for hydration and blemish-prone skin.
• Choose the e.l.f. Pure Skin Back to Basics Mini Kit if you want a simple, gentle three-step routine in travel sizes, especially for sensitive skin or for trying the line.
