    • PROBLEM TO BE SOLVED: To obtain an antiaging agent containing a solvent extract of seeds of peach as an active ingredient, having collagen production promoting action and elastase activity inhibiting action and useful for basic cosmetics, makeup cosmetics, hair cosmetics and bathing agents, etc. SOLUTION: This antiaging agent is obtained by formulating a solvent extract of seed (persicae semen) of peach, preferably in an amount of 0.001-10.0 wt.% as a dried material based on total amount of external preparation. The extract is obtained by immersing peach seed into an extracting solvent (e.g. methanol or acetone) or heating the peach seed in the extracting solvent under reflux and filtering the seed and concentrating the extract solution. A skin lotion such as lotion preparation, milk lotion, cream, ointment, plaster, cataplasm or aerosol is preferable as a formulation of the antiaging agent. The antiaging agent can be formulated with oils and fats (e.g. avocado oil), a surfactant (e.g. base for soap), an antiseptic agent (e.g. methylparaben), a metal ion sealing agent (e.g. edetic acid), a water-soluble polymer (e.g. gum arabic), etc.
