Conclusions after reading officially published studies:

Parabens have not been proven to be harmful. Removing parabens from the formula gives the manufacturer the right to declare a new formulation/new product. Ketones (methylchloroisothiazolinone and methylisothiazolinone), which are often used as substitutes for parabens, have been shown to cause allergic reactions more frequently. Silicones and other substances that form a film on the face are not always bad, as this film protects against contact with free radicals (in the city, for example, combustion products, exhaust fumes, etc., are sources of free radicals). In most cases, the antioxidants in creams do not have time to act, as they are immediately destroyed on the skin under the influence of sunlight. Incidentally, some silicones also have a compensatory effect on sebum regulation, for example. recreate the lipid mantle.
