A: It's a 5% blend of GA + LA (couldn't find specifics of each). Either the "brand expert" is incompetent at his/her job or CeraVe is falsely advertising these as actives.

A: Hello Lilli. Thank you for your interest with CeraVe Skin Renewing Nightly Exfoliating Treatment Gycolic Acid Face Serum 1fl oz.

We do however recommend using CeraVe Skin Renewing Nightly Exfoliating Treatment Glycolic Acid Face Serum - 1 fl oz in the evening, after cleansing and then following with a moisturizer. We hope this information has been helpful and that you can use our products with great success.

A: Hello! While every ingredient we use in our products is evaluated for safety, we do not specifically test our products on women who are pregnant or nursing. CeraVe ensures there is substantial information supporting the safety of our products when used as directed by consumers. However, as there could be certain ingredients that physicians may not recommend for use during pregnancy and nursing, we always recommend that you discuss this with your physician and follow their advice.

A: Hey, Great question! Glycolic Acid and Retinol are two very powerful antiaging ingredients that shouldn't be used together in the same application as there is a high risk of irritation. We recommend to alternate the serums- One night with the retinol serum and the next night with the glycolic acid serum.

A: Hello Zdolla, Thank you for your interest in CeraVe Skin Renewing Nightly Exfoliating Treatment Glycolic Acid Face Serum - 1 fl oz. We do not recommend using this product in the eye area. As an alternative option we suggest you try our Skin Renewing Eye Cream. CeraVe’s Skin Renewing Eye Cream, which was developed with dermatologists, visibly firms and reduces the look of fine lines, crow’s feet wrinkles, puffiness, and dark circles around the eyes. Featuring an anti-aging peptide complex, hyaluronic acid, niacinamide, ceramides, and caffeine, this multi-tasking eye wrinkle cream helps to reveal firmer skin and visibly brighten tired-looking eyes. We hope you will give this product a try soon!

A: Hi there! Thanks for your interest in our Skin Renewing Nightly Exfoliating Treatment Glycolic Acid Face Serum.

Since individual's skin concerns differentiate, we recommend consulting with your medical doctor to see which products are appropriate for your skin concerns and will best benefit you. Should you require further assistance, please don't hesitate to reach out to us.

A: Hi there! Thank you for your interest in our products. It is best when using our Skin Renewing Nightly Exfoliating Treatment to apply evenly to face nightly, after cleansing. This then can be followed by our Skin Renewing Night Cream. We hope this helps!
