Anyone who can afford the equipment to make fresh vitamin c serum could easily afford several years supply of high end commercial products that have been tested to confirm their ingredients and effects.
- jijijijij 1y agoThat’s ridiculous. You need a mg scale and pH strips as equipment (~ 20€, once); tap water, pure vitamin C and sodium bicarbonate as ingredients (~ 6€, lasts for many, many preparations). Aluminium foil to make any glas container light-tight. The chemicals are food grade from your next supermarket or drug store. The "recipe" is used in some studies.
