Sunday Riley Tidal Deep Hydration and Plumping Serum - 30ml

You can use Sunday Riley Tidal serum twice daily, in the morning and evening, after cleansing and before applying moisturizer.

Yes, Sunday Riley Tidal serum is designed to complement other products in the line. It can be layered with other serums and moisturizers.

The serum is formulated for all skin types. However, if you have very sensitive skin, it's always recommended to perform a patch test first.

The primary benefit is multi-layer hydration, which leads to visibly plumper, smoother, and more elastic skin with a refined texture.

Polyglutamic acid can hold more moisture than hyaluronic acid (up to five times more) and helps create a cushiony seal to lock in hydration.

Yes, the lightweight formula absorbs well and creates a smooth base, making it an excellent primer for makeup application.

Allow a few extra moments for the serum to fully absorb. Ensure you are not applying too much product; a few drops are usually sufficient.

Discontinue use immediately and consult the product's ingredient list for potential allergens. If irritation persists, consult a dermatologist.

Ensure you are applying the serum to clean, dry skin. Layering with a moisturizer afterward can help seal in the hydration, especially for very dry skin types.

Ensure the pump is properly screwed onto the bottle. Try gently tapping the pump mechanism or checking for any visible blockages in the nozzle.
