Science: Guerlain Serum Reviews by NvWah

The glycolic acid (AHA) and the “desert rose” ingredients in here are helpful to recover skin from photeodamage, especially the AHA, which is widely recognized as an eraser of many aging-related skin problems. This serum is richly moisturizing too.

However it may not be good to oily and sensitive skins due to some ingredients. See "the Not-So-Good".
