As the causes of enlarged pores are different, an assessment of the causes is conducted before treatment, and good results may be achieved by choosing the appropriate treatment for different causes: for example, enlarged facial pores are mainly caused by the exuberant secretion of sebum, and the oral and topical medication Vimea acid is used to strongly inhibit sebum secretion, and the secretion of sebaceous glands is reduced by inhibiting the secretion of sebaceous glands and regularizing the keratin of sebaceous follicles to achieve enlarged pores. The purpose of reducing the size of pores. If the facial pores are enlarged due to skin aging, the corresponding laser treatment for facial rejuvenation and facial skin reconstruction can be performed. Photorejuvenation uses a specific wavelength range of intense pulsed light source, which is a soft, good light source with good photothermal effect. The application of specific intense pulsed light energy can pass through the skin and use different wavelengths of intense pulsed light to have selective effects on tissues, resulting in different photobiochemical and photothermal properties of the reaction. Long wavelength light stimulates collagen fibers and elastic fibers, causing chemical changes in the molecular structure inside the collagen fibers and elastic fibers of the dermis, coins new arrangement, thickening the collagen tissue, increasing skin elasticity, and improving skin texture, restoring the effect of white philosophers, delicate and elastic. This will improve the facial pore size and the skin itself will not be thinner due to the treatment, but will appear more tight and plump. If the enlarged pores are caused by hair follicle growth, it is expected to be improved by means of laser hair removal. The current more advanced and safe photonic hair removal is considered to be a painless, safe, effective, fast, and water permanent hair removal technique with no side effects. The principle is that the photon hair removal instrument emits special broad spectrum band intense pulsed light directly through the skin to reach the root of the hair follicle, using the absorption of melanin cells in the hair follicle to specific wavelengths of light, so that the hair follicle produces heating, without damaging the surrounding cell tissue, to carry out selective destruction of the hair follicle, so as to achieve the effect of removing unwanted hair. Botox injections are also an option for enlarged pores on both sides of the nose. Botox injections in the dermis can directly affect the trichomes, which is a smooth muscle related to the hair follicle, also known as the “erector spinae”. After Botox injections, the trichomes of the skin are paralyzed and the surface skin becomes loose, thus producing the therapeutic effect of reducing pores.
