What is actually in the bag, additive by additive
Then there is the premium shelf: glutathione, marketed for skin brightening, and NAD+, marketed for energy and longevity. The candid position — the one a good doctor will give you off the record — is that evidence for the cosmetic and anti-ageing claims is thin, and regulators in several countries have pushed back on skin-lightening glutathione marketing specifically. These infusions are not necessarily unsafe when properly administered, but you are paying AED 800–1,500 for something whose benefit is substantially less proven than the saline it is dissolved in. Buy them with clear eyes.
Two practical quality checks apply regardless of the mix. First, additives should be drawn from single-use vials with visible expiry dates, mixed in front of you, not from a pre-mixed unlabelled bag prepared hours earlier in a hot car. Second, some vitamins are heat- and light-sensitive — in a country where a courier's boot can reach 60°C in July, ask how the provider maintains its cold chain. A pharmacy-grade answer involves cool boxes and temperature logs, not a shrug.
