Rated by Lovi · Unbiased, science-based skincare AI trained on real user outcomes · How the Fit score works

Trehalose

Trehalose visibly calms adult blemishes, balances surface oil, extends tear film comfort, and deeply restores skin hydration by locking in vital moisture. It suits those with dry or oily skin particularly well, and you will typically find it formulated within rich creams and targeted peel-off masks. Because of its adaptable nature, it layers easily into any existing daily skincare routine.

Questions and answers

What does trehalose do for the skin?

Skin Research and Technology, 2024

How do you use trehalose?

Trehalose is applied topically to help improve dry skin and hydration, such as through a four-week daily application of sodium trehalose sulfate to decrease water loss and increase skin moisture.

Skin Research and Technology, 2024

Should you use trehalose in the morning or at night?

There is no specific time of day required for using trehalose, as it can be applied whenever needed to help maintain skin hydration.

Can you use trehalose every day?

Yes, you can use trehalose every day as it helps improve skin hydration and barrier function over weeks of regular application. Studies show that consistent topical use over four weeks successfully decreases water loss and increases moisture in the skin.

Skin Research and Technology, 2024

Does trehalose cause purging or irritation?

Trehalose is unlikely to cause purging or irritation as it is a gentle, hydrating sugar molecule that helps retain moisture and support the skin barrier.

Which skin types is trehalose best for?

Trehalose is best for dry skin with top fits like MEDIHEAL Collagen Essential Mask and Isntree Hyaluronic Acid Toner, and also works well for oily, combination, sensitive, acne-prone, and mature skin types. Lovi rates the best fits for dry skin as Superior.
