Glycolic pads are maintenance. They are not a peel, and understanding that difference is most of what you need to know about using them.
Glycolic acid is an alpha hydroxy acid derived from sugarcane. It loosens the bonds holding dead cells to the surface so they shed rather than accumulate. Accumulated dead cells are what make skin look dull and feel rough, so clearing them evenly is what produces the change people notice.
Pads are pre-dosed, which is the practical advantage. Consistent concentration, short contact time, nothing to measure.
Many formulations, including ZO's Complexion Renewal Pads, pair glycolic with salicylic acid. Salicylic is oil-soluble, so it works inside the pore rather than across the surface. That combination suits oily and acne-prone skin better than glycolic alone.
Start at two or three times a week and increase only if your skin stays calm. Sensitive or rosacea-prone skin should start lower or skip acids altogether. Dry skin usually tolerates less than it thinks. Stinging that lingers, redness that stays, or persistent flaking all mean back off.
These are a bridge between in-office treatments, not a replacement for one. If texture or pigment is not responding to exfoliation at home, that is the thing to bring to a consultation.
