Hyaluronic acid and toner are both important components of a skincare routine, but they serve different purposes and are typically used at different times.

Hyaluronic acid is a powerful humectant that helps to attract and retain moisture in the skin. It is commonly used to hydrate and plump the skin, reducing the appearance of fine lines and wrinkles. Hyaluronic acid can be used in both morning and evening skincare routines. In the morning, it helps to provide a moisture boost and create a smooth canvas for makeup application. In the evening, it aids in replenishing the skin's moisture levels overnight.

Toner, on the other hand, is used after cleansing the skin and before applying other skincare products. Its main purpose is to balance the skin's pH level, remove any remaining impurities, and prepare the skin for better absorption of subsequent products. Toners can come in different formulations, such as hydrating toners or exfoliating toners, each targeting specific skincare concerns. It is typically used after cleansing, but before applying serums, moisturizers, or other treatment products.

To summarize, hyaluronic acid is used to provide hydration and plumpness to the skin, and it can be used both in the morning and evening. Toner, on the other hand, is used to balance the skin's pH and prepare it for better absorption of other skincare products, and it is typically used after cleansing, but before applying serums or moisturizers.
