Using PHAs for Smoother Skin Texture

Polyhydroxy acids, or PHAs, are large-molecule exfoliating agents. Because of their significant molecular size, they penetrate the epidermis slowly. This characteristic makes them a consistent choice for individuals who find smaller-molecule acids like glycolic acid too irritating.

The primary function of PHAs is to loosen the bonds holding dead skin cells to the surface. By facilitating this natural shedding process, you encourage a smoother appearance over several weeks. Focus on consistency rather than frequency to achieve desired results without disrupting the surface barrier.

1. Cleanse the skin. Begin with a neutral, pH-balanced cleanser. Remove all makeup and surface debris to ensure the PHA makes direct contact with the skin. Pat the face dry with a clean cloth, as damp skin can increase the permeability of subsequent products.
2. Apply the PHA. Dispense a small amount of the PHA solution onto a clean cotton round or your palms. Press the product gently into the skin, beginning at the T-zone and moving outward. Avoid the immediate eye area and the corners of the mouth.
3. Allow absorption. Wait for the liquid to evaporate completely or become tacky to the touch. This waiting period allows the acid to settle into the upper layers of the epidermis. Do not layer additional serums immediately.
4. Seal with moisture. Complete the routine with a basic, fragrance-free moisturizer. This provides a buffer for the skin and reinforces the lipid barrier. Apply in long, sweeping motions to ensure even coverage.

Exfoliation is about controlled maintenance, not rapid transformation.
