Perfecting Illumination is an antiaging moisturizing cream that contains a cream base as well as natural minerals. For some skin types, it is sufficient to apply this makeup cream without applying any other product below.
Whether you need to apply another product such as a cream or balm before Perfecting Illumination depends on your skin type, skin condition, and climatic conditions.
While for those with normal to oily skin applying Perfecting Illumination may be sufficient, those with dry, dehydrated, or mature skin might benefit from applying a small amount of cream first.
During the summer months, most skin types are adequately nourished with just Perfecting Illumination. However, in winter, some might prefer applying a cream or balm beneath it.
