Cleansing, toning, and moisturizing are the three basic steps of a skincare routine. Cleansing removes dirt, oil, and makeup from the skin, while toning helps balance the skin's pH and prepares it for moisturizing. Moisturizing helps keep the skin hydrated and protected. When choosing skincare products, it is important to look for specific ingredients that can benefit the skin. Some positive ingredients include alpha and beta hydroxy acids, hyaluronic acid, rose water, green tea, vitamin E and C, retinol, vitamin B3, peptides, colloidal sulfur, and niacinamide. Negative ingredients include baking soda, which can overdry the skin, and charcoal, which lacks evidence to support its effectiveness. It is also important to apply skincare products in the correct order, starting with the lightest consistency and ending with the heaviest.
