Glycolic Acid Serum

Smoother skin usually starts with letting go of the layer you no longer need.

Exfoliation, done sensibly

Glycolic Acid Serum loosens dull surface buildup so skin feels softer and looks more even. It is an evening step, and it rewards patience far more than enthusiasm. Start slow, build up, and let your skin set the pace.

• Liquid exfoliating serum built around glycolic acid, an alpha hydroxy acid
• Softens the feel of rough texture on cheeks, forehead and chin
• Best introduced gradually rather than every night from the start
• Keep it to evenings without retinol

How to use

In the evening, sweep it over a dry, freshly washed face, staying well clear of the eye area, then follow with moisturizer. Begin with two nights a week and build from there. Wear sunscreen every morning.

Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.

Questions

How often should I use it?

Start Glycolic Acid Serum at two evenings a week and build from there. Sweep it over a dry, freshly washed face, stay well clear of the eye area, and follow with moisturizer. It contains glycolic acid, an alpha hydroxy acid, so use sunscreen, wear protective clothing and limit sun exposure while you use it and for a week afterward.

Can I use it with retinol?

Not on the same night. We'd start retinol on its own for about four weeks, then give Glycolic Acid Serum separate evenings, such as Wednesday and Saturday. Our night-by-night plan for glycolic acid and retinol shows the full week.
