Enlarged pores come from ageing, excess sebum and imbalanced cleansing. Understanding the causes and aesthetic options is the way to improve pores and skin quality effectively.

Enlarged pores have three main causes: skin ageing (loss of collagen and moisture, with laxity making pores more obvious), excess sebum (too much oil stretching the pores), and imbalanced cleansing (inadequate cleansing allowing dirt to accumulate in pores, while over-cleansing damages the skin barrier).
For enlarged pores and rough skin, regenerative injectable treatments may be considered. Taking a formula combining poly-D,L-lactic acid (PDLLA) with hyaluronic acid (HA) as an example, the design direction includes stimulating the collagen repair process and supporting structural stability of the skin, and is suitable for treatments related to improving skin quality.
In addition, energy-based treatments such as M22 photorejuvenation and fractional laser, by stimulating collagen production and controlling oil, also help refine pores and improve rough texture.
