Hyaluronic acid in cleanser can be beneficial as it helps to hydrate the skin while cleansing, preventing it from feeling stripped or dry. It attracts moisture to the skin's surface, contributing to a more supple and hydrated complexion even after washing.

Hyaluronic acid cleansers are generally gentle and suitable for daily use. Their hydrating properties make them a good choice for most skin types, even those prone to dryness or sensitivity, for both morning and evening cleansing routines.

Some dermatologists express concern about hyaluronic acid's efficacy in very dry environments. In low humidity, it may draw moisture from the deeper layers of the skin instead of attracting it from the air, potentially leading to dehydration; however, this is often mitigated by using it with other hydrating ingredients.

Salicylic acid and hyaluronic acid serve different purposes; neither is inherently 'better.' Salicylic acid is an exfoliant that helps unclog pores, ideal for acne-prone skin, while hyaluronic acid is a humectant that hydrates, beneficial for dry or dehydrated skin. Consider your individual skin needs and concerns when choosing.
