Light, nutritious water-based serums do not suffocate the pores and are suitable for most skin types. Invest in one to survive the crisp autumn.

Almost half the ingredients in Absolution’s Le Sérum Anti-Soif (HK$430/50ml) are organic. Aloe vera and fucocert (a plant-based active ingredient) lend their hydrating powers while elderberry flower extract calms, softens and promotes an even skin tone. The moisturising and antioxidant serum also contains alpine skullcap, which acts as a lipid restorer and an anti-inflammatory. Wild pansy extract, blueberry and sage hydrosol brighten skin and tighten pores.

Alsace’s Truffle Elixir (HK$1,480/30ml) is one of nine products from the French brand’s latest Truffle Skincare series that incorporate the protein and amino acids found in the “black diamond”. The serum, to be applied to the face and neck, not only offers hydration but also penetrates deep into the skin to repair and strengthen cells for a firmer, healthier looking complexion.
