A common condition, usually affecting the face, are enlarged or open pores. Enlarged pores are usually triggered by excessive oils in the skin, when you oil glands, called sebaceous glands, over-produce the natural oils needed to keep your skin healthy.
This excess of oil can block pores, resulting in spots or acne, or simply block the pores and make them enlarged and very visible. Blocked pores can also be caused by hormonal changes, natural ageing and overexposure to the suns UV rays.
There are, fortunately, many treatments designed to improve the appearance of blocked pores, many of them minimally invasive and work by boosting collagen production in the affected areas. This results in firmer, healthier-looking skin with minimal pore visibility.
