Pores are openings present on the skin's surface that release sweat and sebum. In combination to oily skin types, they can dilate due to an overproduction of sebum to facilitate the elimination of this excess sebum. However, as part of the skin's natural renewal process, dead skin cells rise to the skin's upper layer, while new skin cells are regenerated below; but when the skin produces too much sebum, these dead cells, along with impurities, can stick to the walls of individual pores and block them. Factors such as tobacco, excess sebum, pollution or even the sun can also cause pore obstruction.
Sometimes, facial cream can also contribute to pore blockage. This typically happens if the cream being used is not suitable for the skin type. Therefore, before choosing a skincare product, it is necessary to identify the nature of your skin: oily, combination, dry, or normal. For instance, if you use a cream designed for dry skin on oily skin, the skin will end up with an excess of product on the surface, thereby promoting the accumulation of impurities and consequently, the blockage of pores. Similarly, apply the appropriate amount of cream to avoid clogging your pores with an excess of product that would remain on the skin's surface.
Furthermore, it is essential to take the time to cleanse the face before each skincare application to remove impurities on the skin's surface, as well as dead cells. Indeed, these impurities may embed deeply into the pores at the time of cream application if the skin has not been cleaned beforehand.
