To use FlashTenser™ (Quick Skin Tenser) in the formula or pre-serum, how many % should I use? FlashTenser™ (Quick Skin Tenser) when used in the actual formula. will result in a feeling of gooey (like DMAE ), or feel tight and uncomfortable on the skin (like lift now )? Thank you in advance.

Hello, I recommend you to try at 5%. In case of using a high concentration rate, after applying it may feel sticky for a short time. When it dries, there will be no stickiness left, but 5% should not cause a greasy feeling. If found to be gooey But still need to use at 5% may add other ingredients. to help adjust the texture by selecting in the category เพิ่มความนุ่มลื่น - ละลายในน้ำ
