It may be launched by different brands, and the product ingredients and efficacy of each brand may vary. In general, evening is the best time for skin to repair and regenerate. CORE night essence is usually rich in a variety of nutrients and active ingredients, which can penetrate deep into the skin layer, nourish and repair the skin, so that the skin can be effectively repaired and regenerated during sleep. These products often improve the elasticity and firmness of the skin, improving uneven skin tone and fine lines, resulting in younger-looking, healthier-looking skin.
