The smile and skin relation is a science.
The fact that laughter is effective for anti-aging, recovery from illness, and beautiful skin is not a story of image. The smile and skin relation is a scientific story.
In January 2017, a study started in Osaka to prove that laughter can treat cancer.

In addition to this study, we know from various studies that laughter has a good effect on disease and anti-aging.
In this post, we show you how smiles and laughter boost immunity.
Immunity and body
Before discussing about the smile and skin, we will tell you about its benefit for your whole health. When we laugh, we transmit the excitement to the diencephalon, which controls the immune control function, and it produces neuropeptides, signaling substances.
We know that it flows out into the body through blood and lymph, attaches to NK (natural killer) cells, a type of immune cell, and activates them.
NK cells are lymphocytes, a type of white blood cell, and are well-known as cells that exterminate foreign substances such as cancer and viruses.
They say that 3,000 to 5,000 cancer cells are generated each day in the body of a healthy person. The presence of cancer cells does not mean one has cancer, but the excessive growth of cancer cells leads to cancer.
When the body is healthy, NK cells exterminate cancer cells. So even if cancer develops, the human body returns to a healthy state every day.
Smile boosts immunity against infectious diseases.
NK cells also protect against viruses and bacteria, so they help prevent infectious diseases.
That’s why you’re less likely to catch a cold; even if you do, you’ll recover faster.
They say there are as many as 5 billion NK cells in our body, and when we laugh, NK cells are activated, boosting our immune system.
On the other hand, if the immune system becomes too strong, it can lead to autoimmune diseases such as rheumatoid arthritis and connective tissue diseases. There seems to be little risk of it increasing for now.
From this, laughter seems to have a connection with anti-aging.
Conversely, sadness and stress reduce the vitality of NK cells.
As a result, your immune system deteriorates.
Smile and skin’s immune system
So, does laughter boost the immune system of your skin?
The skin is also a part of the body. So, of course, it is thought that it does.
Improving immunity is expected to positively affect skin infections, rough skin, and atopic dermatitis, but there seems to be insufficient research on this point.
By the way, the Langerhans cells in the epidermis are responsible for the skin’s immunity.
Although many aspects of Langerhans cells are still unclear, we have found that they function as a control tower for skin barrier function and are deeply involved in atopic dermatitis.
