Botanical source: Silybum marianum (L) Gaertn.

Used part: seeds

Solubility: Water (0.5 mg/ml at 25.0 C), non-denatured ethanol

Solubility notes: I use Silymarin in a serum that contains non-denatured ethanol.  According to the MSDS, 0.5mg will dissolve in warm water. According to my experience (and the MSDS) it will dissolve completely in non-denatured ethanol, or a combination of water and non-denatured ethanol.

Suggested percentage: 2% to 5%

Silymarin for DIY skin care from BulkActives

About Silymarin

Silymarin 80% is a natural skin care ingredient taken from the milk thistle plant. There are many studies that show it to be effective as an anti-oxidant, an anti-inflammatory, and for UV protection and repair.

"silibinin protects against UV light-induced DNA damage and cancer cell growth."

Silymarin, is the active ingredient of the fruit of the milk thistle.

 

Silymarin is a mixture of at least seven flavolignans and one flavonoid.

 

The most abundant and potent costituents in silymarin is silybin (also called silibinin).

Silymarin in skin care - research

 

Topically applied silymarin may:

 

  • act as an anti-inflammatory:  [19] [18] [16] [12] [9] [3]

 

  • help with acne (rosacea): [18]

 

  • act as an anti oxidant:  [15] [14] [9] [5] [4] [3] [2] [1]

 

  • repair and treat sun damage:  [15] [14]

 

  • prevent or reduce UVA and UVB sun damage:  [23] [22] [20] [17] [12] [11] [10] [9] [8] [7] [5] [4] [3]
