Has the effective effect that is attributed to it. I use it as a night cream or under night or day cream.

FAQ

Yes, we recommend applying a day and night cream after your serum. The hydrating serum is not a replacement for a cream but an extra step that boosts your skincare routine.

The Ray Day and Night Creams contain nourishing oils that help retain moisture and keep your skin soft — something a serum alone doesn’t do.

Absolutely! The hydrating serum is also suitable for oily or shiny skin. The formula is lightweight and contains active ingredients that deeply hydrate the skin without clogging pores or leaving a sticky residue.

The hydrating serum works quickly, and many people notice a difference right away — especially after just a few applications. Your skin feels softer and more comfortable.

Thanks to the action of hyaluronic acid in the hydrating serum, your skin stays hydrated throughout the day.

With regular use, you’ll often see an improvement in overall skin texture, suppleness, and radiance after just a few days to weeks.
