What does '4D hyaluronic acid' mean, and why is coconut oil in the formula?

'4D' refers to the way hyaluronic acid is included in the formula: as a blend of molecules of different sizes. These different molecular sizes are used to hydrate on several levels of the skin surface, rather than only at one depth. This helps reduce the feeling of tightness and gives a plumper, fresher appearance.

Coconut oil is included for its emollient properties. It helps soften the skin surface and smooth rough texture. It also helps reduce moisture loss by forming a light protective layer, which is useful when skin feels dry or in cooler weather.

Together the two ingredients balance each other. Hyaluronic acid binds water and brings hydration; coconut oil helps keep that moisture from evaporating too quickly. This combination is typical for a nourishing day cream with a richer feel.

If your skin is oily, you can still use this cream, but apply a smaller amount or focus on areas that feel drier. If your skin is very reactive, patch test first. Avoid the eye area.
