You can minimize the appearance of your pores, but because pore sizes are genetically determined, you can’t really shrink them.
Your pores can get stretched out when they’re consistently clogged, which makes them appear bigger.
Aging and exposure to UV rays and pollution can lead to loss of collagen which can in turn increase your pore size.
Instead of shrinking pores you can move to making them less visible.
Pores are genetically determined, depending on how your glands are structured. People with dry skin and fair skin tend to have smaller pores while oily skin and darker, more olive skin tones, tend to have more visible pores.
The best way to prevent pores from getting larger is to exfoliate and to wear sunscreen. Salicylic acid exfoliates differently than alpha hydroxy acids like glycolic acid and lactic acid. Salicylic acid is oil soluble, meaning it’s able to get inside pores to gently push out dead skin, bacteria, sebum, and any other pore-clogging debris. By removing that debris from your pores, your pores will appear smaller.
Retinoids help increase cellular turnover and stimulate collagen production. By increasing cellular turnover, it effectively exfoliates dead skin cells, dirt and oil. Collagen also helps your skin look firmer, minimises the appearance of pores.
Microdermabrasion is also recommended for most skin types. Avoid pore-clogging ingredients, like heavy oils, and look for non-comedogenic makeup and skincare brands that are specially formulated, so they don’t clog pores, cause irritation, or lead to breakouts.
