Just wish it were refillable
I use the full-size F-Layer serum daily, but I like this little one for travel. Just wish it were refillable - it doesn’t hold much, so feels like a waste of plastic.

Amazing product!
I bought the travel size just to minimize amount of products I travel with, amazing stand alone on hair that requires a lot of work to keep it in line. Will absolutely be buying the full size!
