"18 again" is a ' a vaginal rejuvenation & tightening gel' and I don't even want to know what that means but I'm guessing it's "rip-off in a jar". The advert selling this cream hints at what it accomplishes by having a presumed mother and housewife invite her (presumed) hubby to sing and dance like a young Bollywood star, while small children and the older generation stare, mouths agape. They've understood what the cream did for her - making her "feel 18 again" - and so the "button" on this ad is how the older woman orders it online for herself.
Dear, oh dear. "Vaginal" tightening gel. You mean this goes inside? This is worse than Lysol as a contraceptive.
