Technical Details & Test Data
- Selective Sebum Absorption
No matter how old you are, you might find yourself with the oily, pore clogged skin that leads to acne. Oily skin is a result of excess sebum production from sebaceous glands on the face, neck, chest and back. Excess sebum production is in part because of hormones and hereditary factors and commonly persists beyond adolescence. Fortunately, there are a variety of effective ways to control sebum and clear oily skin, regardless of the forces that cause it.
Need to absorb not moisture but sebum on skin selectively
I can understand that hydrophobic porous PMMA or SUNSIL OLEO can selectively absorbs oil over water when it’s dry.
However, if it’s in emulsion(i.e. skincare) and it’s soaked, can it still absorb oil over water?
Safety & Health
- Toxicology
The information available on SUNPMMA gives no indication of any risk of toxicity, if the application and the concentrations used are as recommended.
