Previously used
CeraTouch old creamy The recommended usage rate of the old one is 3-10% with a price of 79-262 baht (approximately from the price of 40 grams 1049 baht), but the new type (powder) usage rate: 1-7%, price 145-1015 baht. (3-4% recommendation, price 435-580 baht) (approximately from 20 grams, 2899 baht) Questions 1. Usage rate [Powder type]
Ceramide Complex (
CeraTouch ™, Powder) is the correct recommendation? (Usage rate: 1-7% (recommended 3-4%)) 2. How is the powder type better than the former? Because the price is very different (compared to the recommended maximum quantity) 3. Why is there a change in the condition of the raw materials? because it seems to make the cost much higher I still don't know the way to adjust the product formula because of the increasing cost. Thank you in advance for reading and answering questions in detail.
