What the gurus are saying

The medical-grade label alone doesn't guarantee superior performance compared to drugstore skincare products, even when brands like iS Clinical invest seriously in clinical research and studies. Some creators are loyal users who spend $100-250+ per serum or oil, while experts caution that many so-called medical-grade products aren't actually more effective than drugstore alternatives, which often have equally robust research backing.

"Some brands that use this term, like iS Clinical, do put money into serious clinical studies, and that research is valuable, but there are plenty of over-the-counter products with excellent clinical studies behind them. And there are also plenty of so-called medical grade products that aren't any more effective than what you can find in the drugstore."

"She uses a lot of iS Clinical oils and serums that cost two hundred to two hundred and fifty dollars each, and her eye cream is from iS Clinical at a hundred and five bucks."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Salicylic acid

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
