This type of skin must be hydrated regularly from the inside (drink that water) and outside (with hydrating mists like the MAC Mineralize Charged Water $32 from MAC counters) as well as moisturised with oil-based rather than water-based creams. The Avène Rich Compensating Cream ($62 from Priceline) is full of vitamin E and works hard to compensate for skin’s lack of moisture. The Avène Skin Recovery Cream ($38.95) is also a great option if your skin is dry and sensitive (from climatic conditions or harsh cleansers/irritating cosmetics etc.).
Dry skin also benefits from hydrating masks (like Egyptian Magic $34.99 from Priceline or Sephora) and facial oils (like the Sunday Riley Flora Face Oil $144 from Mecca Cosmetica).
