The role of trehalose in skincare products on the skin.

Hello, everyone! Your editor is here again, meeting you rain or shine! The weather has been getting hotter and hotter lately, and I’ve almost reached a point where I can’t survive without air conditioning. In this increasingly scorching season, our demands for the frequency and quality of skincare and makeup products are also higher.

I believe that those of you who have some knowledge of skincare product ingredients have noticed that “trehalose” is a repeated ingredient in many popular skincare products. It can be found in numerous skincare and cosmetics. Today, I’m here to share some information about the benefits and effects of trehalose in skincare products, helping you choose the right skincare products for your needs.

Hydration and Moisturization

As the name suggests, trehalose is derived from algae that grow in the ocean, which naturally contain high levels of moisture. Even in dehydrated conditions, trehalose can provide an adequate amount of moisture, just as it does for its own growth. Trehalose can help your skin stay within a normal range of activity when it’s dehydrated, complementing hyaluronic acid.

Radiation Protection

Trehalose is effective in countering the harm that radiation can cause to the skin. It can eliminate the OH· free radicals produced by alpha and beta radiation. So, when you’re exposed to radiation from computers or mobile phones, especially if you work in front of a computer for extended periods, you can choose skincare products with trehalose to maintain the stability of your body’s DNA.


There’s a group of antioxidants called polyphenols, and trehalose is particularly effective at countering polyphenols. These two substances can counterbalance each other and help maintain the stability of polyphenols during their antioxidant process, which promotes the anti-aging effect on the skin.

Enhanced Skin Resilience

Trehalose has a relatively small molecular weight, making it easily absorbed by the skin’s epidermal cells. It can play a role in protecting the skin from dryness and cold, thus enhancing the skin’s resilience. It provides some buffering effect in various extreme environmental conditions.

When dealing with the past, don’t get entangled, don’t be stubborn, choose to let go and find peace. When facing reunions and separations, learn to cherish, and you’ll be able to face the future with composure, which is a way of being kind to yourself.
