Clean your face first, then put a small amount of cream on your face and neck while the skin is still slightly damp. Hyaluronic acid binds water on the surface, so damp skin makes the product feel more comfortable and spread more evenly. You can use it both morning and evening; the source says it fits into a simple regimen for times when the skin feels tight, looks flaky, or needs a fresher appearance.
If you use a toner or a water-based serum, apply them before the cream and wait about a minute. In the morning, finish with sunscreen after the cream has absorbed. In the evening, the cream can be your last step unless you use a separate overnight product. You do not need a large amount: a thin layer is enough to cover the face, and you can add a second layer on drier spots if they still feel tight.
For a lighter feel, use less product rather than skipping it; for a richer feel, apply it to slightly damp skin or follow with a bland occlusive moisturizer on very dry areas. This way you control the finish without changing the product.
