Night
In the bustling life of Hong Kong, skincare has become an essential daily routine for many. However, with numerous products vying for our attention, do we truly understand how to use skincare products correctly? Today, we will delve into why retinol should be used at night and highlight the differences between morning and evening skincare.
Firstly, our skin actually has its own physiological clock. This means that the state of our skin differs between morning and night. In the morning, our skin needs to protect itself from external environmental stimuli, while at night, it enters a golden period for repair and regeneration. These differences stem from several biological characteristics of the skin, including the effects of light, the activity of sebaceous glands, and the process of cell regeneration.
During the day, ultraviolet rays from the sun can harm the skin, so using products with antioxidant properties such as Vitamin E can help reduce the impact of sunlight. In contrast, evening skincare focuses on nourishment and repair, especially since the skin tends to lose moisture more quickly at night, necessitating richer moisturizing ingredients to combat this loss.
Products like retinol, known for their potent repair and regeneration effects, are best utilized at night. During this time, the skin’s absorption capacity is at its peak, and blood flow is enhanced, allowing active ingredients to deeply penetrate the cells for regeneration. Additionally, the skin tends to renew itself more rapidly at night, which explains why using retinol in the evening can maximize its effectiveness.
Moreover, during the day, our sebaceous glands are more active, producing more oil. Therefore, for oily skin, increased sweating and oil production in the morning necessitate more diligent cleansing. Conversely, the nighttime environment is drier, meaning additional hydration and moisture retention become crucial.
Additionally, when it comes to combining various skincare ingredients, clients often inquire about the use of Vitamin C and Vitamin A together. The pH levels of these two ingredients differ, and using them simultaneously may hinder their effectiveness. Therefore, it is advisable to use Vitamin C in the morning for protection and Vitamin A in the evening for repair.
In summary, the focus of daytime skincare is protection, while nighttime skincare emphasizes repair. Regardless of skin type, understanding one’s skincare needs and choosing appropriate products at the right time is vital. Lastly, it is recommended to read ingredient lists carefully when selecting skincare products and to ensure that they are paired appropriately for morning and evening use, allowing the skin to receive the best care at all times.
