One of the key steps in any k-beauty routine is the use of serums. Serums are liquid rich in active ingredients to repair and restore your skin. It is the main skincare product to treat your underlying skin issues, whether it be extreme dry skin, hyperpigmentation or blemishes. It also functions to maintain your skin radiance by nourishing the skin with plenty of antioxidants ranging from Vitamin A to Vitamin K.
How often should you use a serum? Most serums are formulated to be used safely twice a day in your morning and evening routine. Serums that contain Vitamin C are appropriate to be used in your morning routine to help boost the effectiveness of your skin's protection from free radicals, where as serums containing retinol are more suitable to be applied in the evening routine because they tend to be more irritating on the skin and the efficacy decreases when exposed to UV rays.
Whether you are looking to hydrate, nourish or rejuvenate, your choice of key ingredient is crucial in ensuring that the serums are treating your underlying skin concerns.
