For oily or breakout-prone skin, the focus should be on lightweight, water-based formulations. Avoid heavy oils or waxes that might clog pores.

A simple routine of a Glycerin-based toner followed by a lightweight HA serum is often sufficient.

If you find your skin feels dehydrated despite being oily, adding a thin layer of PGA can help regulate the skin's moisture levels, which may actually reduce excess sebum production caused by dehydrat

ion.

For dry or mature skin, the routine can be more robust. Mature skin often struggles with a compromised barrier and reduced natural production of glycosaminoglycans.
