The present invention relates to a cosmetic composition containing snail mucus consumed with berries and fruit, and a process for producing the snail mucus. More specifically, the present invention relates to a cosmetic composition containing snail mucus, Snail mucus is obtained from snails fed with fruit to enhance skin regeneration, skin elasticity and moisturizing power by mucin, collagen and elastin contained in snail mucus. Snail mucus, which consumes berry and fruit among the cosmetic composition of the present invention, The present invention relates to a cosmetic composition which is harmless to human body as a raw material and contains snail mucus which absorbs berries and fruit to prevent skin troubles by calming skin stress caused by an external environment and a process for producing the same.The present invention relates to a method for growing a snail on a berry and a fruit seedlings at a temperature of 20 to 35C and a humidity of 60 to 80%, wherein the berries are selected from the group consisting of blueberry, aronia berry, , A snail mucus containing collagen and an elastin component is obtained, wherein the snail mucus contains polyphenol which is a component of berry and fruit, and the snail slime containing the berry and the fruit ingredient is filtered in a filtration apparatus equipped with a porous filter body, Characterized in that a mucus filtrate is obtained and the collagen decomposition inhibitor or elastin decomposition inhibitor is contained in the snail mucus filtrate.The present invention relates to a method for growing a snail at a temperature of 20 to 35 DEG C and a humidity of 60 to 80% (S10) in a berry and a fruit seedlings, said snail being washed for 30 to 8 hours (S30) of obtaining a snail mucus filtrate by filtering the snail mucus in a filtration apparatus equipped with a porous filter body, a step (S30) of collecting the snail mucus, and a step (S40) of adding a decomposition inhibitor and the step (S50) of preparing a cosme
