Buying Guide: Key Purchase Considerations
- Hydration duration: Look for serums that offer long-lasting moisture (24–48 hours) and check reviews for real-world performance on sensitive skin.
- Active ingredients: Prioritize humectants like hyaluronic acid, and consider supporting ingredients such as glycerin, squalane, ceramides, or oats for barrier support.
- Skin sensitivity: For eczema-prone or highly reactive skin, fragrance-free formulas and dermatologically tested labels reduce irritation risk.
- Texture and absorption: Lightweight gels or serums that absorb quickly help prevent residue and clogging pores, especially under makeup or sunscreen.
- Routinely pairing: Many serums pair well with moisturisers or cleansers; consider compatibility with existing products to maximise hydration without redundancy.
- Ethical considerations: Vegan options, fragrance-free formulas, and packaging choices may influence selection for sensitive or ethical concerns.
- All-day vs. targeted use: Some serums are designed for morning use, others for night, while some are versatile; plan around your daily skincare rhythm.
- Allergy testing: If you have known sensitivities, perform a patch test on a small area before full application.
