The serum is enriched with numerous antioxidant agents as described in the previous question. Hence every time it is applied to the skin, neutralisation of free radicals is occurring at a cellular level apart from providing a barrier on an external level to prevent further free radicals from forming due to exposure to harmful sun rays or pollutants. This enhances the process of reduction of age spots to take place at an accelerated rate. Therefore, even though results vary from one individual to another, one may notice a gradual fading of age spots after a brief period of time. Some users of this product have reported a change after about two weeks. We do however recommend you to be consistent in the use of the serum and use it twice daily, in the morning and in the evening before retiring for the night to give your skin the best chance and to get best results from the product.
