Enlarged pores are especially a problem for people with oily or combination skin. They not only disrupt the skin's appearance but also, due to their larger openings, clog more quickly and promote the formation of blemishes. They are caused by a buildup of sebum, which occurs particularly in oily skin due to an overproduction of sebum and prevents sebum from exiting the pore. The result: the pore enlarges.
Additionally, the formation of enlarged pores is favored by a lack of pore elasticity, increased hair follicle volume, chronic acne, hormones, stress, as well as milk and carbohydrates. A daily, thorough cleansing routine and products containing tea tree oil or BHA (salicylic acid) can help minimize enlarged pores and smooth the skin's appearance. Also, when applying makeup, it is important to use a primer before foundation. This prevents the foundation from settling into the pores and clogging them.
