Serums are skincare products you can apply to your skin after cleansing but before moisturizing with the intent of delivering powerful ingredients directly into the skin.
Serums are particularly suited to this task because it is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. This makes them a great tool for targeting specific skincare concerns, like acne prone skin or hyperpigmentation.
NKVSKIN serums are highly concentrated and active; this means that they need to be applied first, to clean skin. This way all the active ingredients can penetrate your skin.
A serum can be applied in the morning, at night or both.
