The initial set of The Ordinary contains three essential products for daily skincare. The Squalane Cleanser removes makeup and cleanses the skin while hydrating it. The Hyaluronic Acid 2% + B5 hydrates the deeper layers of the skin, and the Natural Moisturizing Factors + HA is perfect for daily use, strengthening the skin's natural protective barrier. These products are the fundamental pillars of any skincare routine.
