Phyto-C definitely charges a ton for their products but they're worth every single penny! I've been using the Superheal O-Live serum for about a year now and it really helps with my rosacea and keeps my skin hydrated and looking amazing without the heaviness of a cream. Very, very good stuff.
The worst company ever they take from me 2500 US dollar with no goods
Be carefull all to deal with such a company

Answer: Doesn't look like they use anything that causes serious side effects. Some products do contain retinol which can burn/itch when you first start using it.
