Hyaluronic Acid

Hyaluronic acid is one of the most popular ingredients in skincare. What does hyaluronic acid do? Its main role is hydration, helping skin look plump, smooth, and radiant.

How to use it

You can use hyaluronic acid any time of day, in any season, during pregnancy, and at any age. You’ll find it in creams, serums, toners, and other skincare products. It works best in leave-on products that stay on the skin longer.

Lightweight, watery textures like serums should be followed with a richer product, such as a cream, to help lock in moisture and prevent the skin from feeling dry.

Suitable for

All skin types, especially dry or dehydrated skin.

FAQ

1. Can I use hyaluronic acid with retinol?

Yes, you can use hyaluronic acid with retinol. That’s why it's often included in products with retinol to help reduce irritation and minimize side effects.

2. When should I apply hyaluronic acid in my routine?

It can be used twice a day (both in the morning and evening). Hyaluronic acid for skin is especially helpful when you use strong treatments (for example, chemical peels) or apply ingredients that may dry out the skin (such as retinol and acids).

3. How long does it take to see results from hyaluronic acid?

Hyaluronic acid hydrates the skin, and attracts and retains moisture. The effects can often be seen almost immediately. However, for more visible and long-lasting results, it's recommended to use it regurally for at least one month.
