Day & Night Serum Travel Size

The retinal is genuinely gentle—I jumped straight from a mild retinol and only dealt with the slight flaking I expected. The glass skin serum sits nicely under moisturizer without pilling, and this duo covers my whole routine in one tiny bottle.

The retinal is surprisingly gentle for a first-timer coming off the mildest retinol—just a bit of expected flaking for two days. And the glass skin serum layers nicely under moisturizer without pilling. Both in one tiny set that lasts way longer than you'd think.

The travel size is perfect for tossing in my gym bag, and the glass skin serum leaves my face feeling dewy without any greasy residue. I’ve been layering it under moisturizer every night for two weeks and my skin looks noticeably calmer in the morning.
