Abstract
Nanosized reduced graphene oxide (rGO) is found in active microcarbon used in popular face cream from the manufacturers like Ponds, Nevia, and Garnier which, under visible light exposure, gets activated by aerial oxygen to generate reactive oxygen species (ROS) harmful to skin.
Highlights
Activated carbon powder has long been in use in the purification of water (Shannon et al 2008), sugar (Harris 1942), and other food materials (Roy 1994)
The corresponding atomic force microscopic (AFM) images support the presence of spherical nano carbon in sample P and graphene like sheets in sample N and G (Fig. 1d–f), respectively
The standard MTT assays suggested that these isolated reduced graphene oxide (rGO) has cytotoxic effect on HaCaT cells (Fig. 7)
Summary
Activated carbon powder has long been in use in the purification of water (Shannon et al 2008), sugar (Harris 1942), and other food materials (Roy 1994). The base slogan of such advertisement is to combat dark spot, acne, oily skin, and environmentally inflicted damages on the exposed face outdoor The introduction of such a cream to get away with all these problems is credited with the addition of active microsized carbon with the additional advantage of getting fairer skin day by day. On application of such face cream may result quick effect where the known adsorbing property of microcarbon acts. Ponds pure white deep cleaning facial foam (P): 10 gm of P was taken in 100 ml beaker containing 80 ml 1:1 dichloromethane:ethanol mixture It was sonicated for 5 min and centrifuged for 3 min at 4500 rpm. Cells were mounted and observed through red filter (ex: 512–552 nm, em: 565–615 nm) under inverted microscope (Nikon eclipse TίU, Japan) equipped with 609 (S Plan Fluor) objective
