Let's find out what is the charm of snail secretion through this posting.


▶ What is snail secretion?

Snail secretion is secreted by the glands of snails, and it protects the surface of the snail's skin and moisturizes to prevent it from getting dry.

This role of secretion is very important and essential for delicate skin of snails. Snail secretion consists of complex glycoproteins that combine various types of sugar, protein, and amino acid, including water.

In particular, most of them consist of water and also include small amounts of active ingredients, which play a key role in the effects of snail secretion.

Ingredients of Snail Secretion

It is seemingly different, but snail secretion and our skin actually has very similar ingredients.

Just as snail secretion protects the snail's body, our skin is part of the body and also plays a role in protecting the body. 

Ingredients inside the skin

Our skin is subdivided in layers and the inside is filled with various components.

Key components include collagen, elastin, hyaluronic acid, and glycosaminoglycan, which are also found in the snail secretion mentioned above.

In other words, the appearance is very different, but there are many similar ingredients in our skin and snail secretion.
[Reference] Acta Cirurgica Brasileira, 2010, 25, 460–66

Therefore, snail secretion is consistently used as a skin-friendly and beneficial ingredient, and it is considered as the representative ingredient that is safe without irritation.

In addition, it is also easy to use with various ingredients because of its mild ingredient that is not complicated.

1. Skin Renewing (Remodeling) Effect

As getting older, skin cell activity naturally decreases, and early aging is also deeply related to this skin cell activity.

Snail secretion(Mucin) has a skin regenerative effect that accelerates the activity of fibroblast and keratinocyte, which are kinds of skin cells, and quickly fills up with new skin cell.
