4. Uriage

Thermal Water Spray

Hydration sprays are the ultimate multitasking heroes in any skincare routine. These refreshing mists deliver an instant boost of moisture without clogging pores or weighing down your skin. If you’re dealing with dryness or dehydration, a hydration spray helps lock in the benefits of your serums and moisturisers, creating a lasting veil of hydration. But the benefits don’t stop there. After applying makeup, a quick mist helps powders and creams blend smoothly, setting your look with a soft, dewy finish. You can also use it throughout the day to refresh your skin, cool down after a workout, or soothe sun-exposed areas. Gentle, versatile, and easy to use, hydration sprays are a must-have in any daily routine.

One standout pick is the Uriage Thermal Water Spray — a French pharmacy favourite trusted by dermatologists. Sourced from the French Alps, this mineral-rich mist contains calcium, magnesium, and trace elements that help strengthen the skin barrier, calm irritation, and reduce redness. Unlike regular facial mists, Uriage is isotonic, meaning it hydrates without disrupting your skin’s natural balance. It’s ideal for all skin types, especially sensitive or post-procedure skin. Use it in your morning routine, as a midday refresh, or even as a makeup setting spray for a soft, radiant finish. Affordable and incredibly effective, Uriage proves that great skincare doesn’t have to be expensive.

Rating: ⭐️⭐️⭐️⭐️
Best for: Redness, post-acne marks, or sensitive skin refresh.
