The invention concerns cosmetic compositions containing a combina¬ tion of functional ingredients of vegetal origin, one consisting of tamarind gum polysaccharide and the other consisting of a beech tree buds extract, which contains a pool of medium-low molecular weight molecules, among which flavonoids, polyphenols, water-soluble peptide fractions, amino-acids and mineral salts. Specifically, the compositions comprise from 0.1 % to 2% by weight of tamarind seed polysaccharide (Tamarindus lndica Seed Polysac¬ charide) and from 0.5 to 15% by weight of beech tree buds extract (Water (and) Fagus sylvatica Extract). The combination is useful for the manufacture of cosmetic products having moisturizing, conditioning, energizing and mineralizing action, which present a potentiated ability for improving the elasticity properties of the skin and which present a high anti-wrinkle effectiveness.
