Milk thistle and moldavian dragonhead are sources of fatty oils with high content of polyunsaturated fatty acids, especially linoleic acid and α-linolenic acid. These fatty acids, together with other biologically active substances have positive effects on regeneration processes in skin, help improve natural functions and provide an effective protection against negative external effects. As a consequence of naturally high polarity of both oils, the oils can be used in cosmetic products in high concentrations, without negative effects on their useful properties, such as absorption, spreading or feeling of stickiness. Milk thistle and Moldavian dragonhead oils are especially ideal for the creation of formulas designated for ageing, sensitive or irritated skin.
