Cover FX BritePrep FX Brightening Foundation Primer SPF50 (30ml, 45 CAD) ตัวแรกที่แลกมาก็คือ primer ตัวนี้ ตอนแรกลังเลระหว่างตัวนี้กับ Skinprep FX Nourishing Foundation Primer & Anti-Aging Serum ราคาเท่ากัน ส่วนผสมตัว nourishing น่าใช้กว่า แต่ตัว briteprep มันมี SPF50 ดัวย ก็เลยตัดสินใจเอาตัวมีกันแดดมาดีกว่า เดี๋ยวรอบหน้าค่อยสอยอีกตัว
I've used the fine L-AA and found the same problem. Heat will help to dissolve it better but it will degrade its potency. That's why I never buy fine L-AA again.
I suggest that you use a bigger bottle with less L-AA and more water and give it a very good shake na ka. But you will not get as concentrate as you would with the ultra-fine one ka. Make sure you get it dissolved completely otherwise it will scratch and burn you skin na ka.
One thing you can do with it. Mix it with cream and use it as facial scurb ka. It would give you similar effect that Olay MD and L'oreal MD offer.
Dear K Phoebe Thank you verymuch for your suggestion kub, next time I will order L-AA at //www.bulkactives.com/ . Someone said that bulkatives sells an ultra-fine grade of L-AA :) L-AA has already bruned the corner of my mouth >< I may have to use a heat to dissolve it as your suggestion.
Ps. I'm finding a glycol and squalane to make a serum but I cant' find it at bulkatives. I may have to use a good toner to mix it.
I got mine (both squalane and ultra l-aa) from makingcosmetics.com but I don't know if they will ship their products to Thailand. The shipping can be more expensive than bulkactives.com, though.
To order 120 grms of L-AA, makingcosmetics.com also ship to Thailand but the shipping rate is 36$ By USPS. !!! It's only $11.85 by EMS for bulkactives.com because thier company is located in Taiwan. :)
I think I will use Paula's choice toner to be a solvent for my DIY serum kub.
Thank you for sharing your amazing experience about DIY serum kub.
