Where does this serum fit in my skincare routine? — DNC Hyaluronic acid 3 ml (hyaluronovaya acid)

Apply the serum after cleansing and toning, while your skin is still slightly damp. If you use treatment serums such as vitamin C, niacinamide, retinoids, or exfoliating acids, apply those first on dry skin, let them absorb, then lightly mist or splash water on the face before applying this hyaluronic acid serum. The damp surface gives the humectant immediate water to bind. Finish with your moisturizer or facial oil to seal in the hydration and reduce water loss throughout the day or night. In the morning, follow with sunscreen as the final step. The lightweight texture makes it easy to layer without pilling or heaviness, even under makeup. If your routine is minimal — just cleanser, this serum, and cream — that is perfectly effective for maintaining surface hydration. Adjust frequency based on season and how your skin feels: twice daily in dry, cold, or heated environments; once daily or every other day in humid conditions or if your skin is naturally well-hydrated.
