Copper Peptide dissolved at the shop 1000ppm, equivalent to 1% in solvent, which the shop recommends to use in the amount of 1- 3% means that even if it is dissolved in the amount of 1%, it has to be dissolved again to achieve a concentration of 1-3% again, right? We can't use 1000ppm to apply directly on the skin for 100%, right? which compared to the powder form It must be dissolved in a solvent to reach the recommended concentration of 0.01-1%, and if it dissolves to 1%, it can go directly onto the skin as well. It shouldn't be any different from the 1000ppm melted one, so 1000ppm should be able to be applied directly to the skin as well. Is that correct? Thank you.

Hello, if using powder type, use 0.1% to get concentration = 1000ppm. If using liquid type, use 100%, will get concentration = 1000ppm. From the results of past research. It is also recommended to use The liquid type at 1-3% (or equal to the concentration of peptide at 10-30ppm), but because of the current There are many brands of products. It is used in very high concentrations. The company is sold as a powder. in case of wanting to make a formula with a concentration higher than 1000ppm
