我們都知道含Vitamin C 的護膚產品對肌膚的保護和修複超級好。市麵上有很多昂貴含Vitmamin C 的護膚產品,但這類產品通常有個共同的問題:其中的Vitamin C 成份很不穩定,容易氧化失效(這是Vitamin C 本身的問題)。如果你用過許多含Vitamin C 的護膚品,一定對我的話深有感觸。這類產品用到後來都會變色(Vitamin C 已氧化失效的象征)。我知道許多護膚品的知識,完全可以自己配用,但很少這樣做(新鮮的麵膜除外),其中最重要的原因就是防腐的問題。因為用來配護膚品的材料都是營養極其豐富,如果不往裏麵加點防腐劑的話,配好的護膚品會很容易有大量繁殖的細菌,對皮膚是極其有害;加點防腐劑吧,又極難掌握其用量。因為用少了起不到防護的作用,用多了對肌膚是種傷害。所以除了這款精華素和一些現用的麵膜外,我不會去配用其它護膚用品。
廢話少說,請大家看成份:
1/4 到 1/2 tea spoon Vitamin C powder(根據自己膚質摸索用量,從少量用起)
4 tea spoon pure water
2 tea spoon pure Aloe Vera Gel
1 or 2 drops Vitamin E (選擇)
配這款精華素的關鍵是Vitamin C powder 要先完完全全溶解在純淨水裏再混合其他的成份搖勻。配好後,不用放冰箱,僅僅用一星期而已。
護膚之王其實是含維生素C的產品,但是就如我前麵提到:維生素C一旦溶於水後就極不穩定,易氧化失效,所以現在我會自己來配。這類產品中的Vitamin C 的濃度要達到3%-10%才能有效,現在的研究證明最高可以達到17%-20%,在20%以後就對皮膚有刺激和不好的作用。其實每個人的膚質都不同,例如我自己就非常敏感,先生就好一些。所以我倆的配方裏Vitamin C 的用量是不一樣的。
過120美金的。最常用的叫 Skinceuticals CE Ferulic,用了它將近5年,每次用到後來都變色(氧化),所以就開始自己配了。這款產品裏麵的的有效成份就是Vitamin C,Vitamin E(微量,大概1%)和Ferulic Acid。其中Ferulic Acid 是用來穩定Vitamin C 的。Paula的產品其實就是仿 Skinceuticals CE Ferulic的產品,估計用到後來也會變色失效。
補充一下,發現Paula的Vitamin C 產品是20ml一瓶裝的(而Skinceuticals CE Ferulic是30ml一瓶)。這比較聰明,但用到最後估計還是會變色氧化失效的。
Vitamin C 精華素效果到底怎樣?可以說年過30,你還想要完美flawless skin的話,隻能靠它了。貼一下Amazon的一位用戶對Skinceuticals CE Ferulic的評價,這也是我想要說的話: 45 of 48 people found the following review helpful
This review is from: Skinceuticals CE Ferulic, 1-Ounce Bottle (Health and Beauty)
C E Ferulic's immediate effects will vary from person to person. Some people may experience immediate brightening, toning and improvement in their skin texture. Other's may not be able to tolerate it well and get inflammation. I recommend using it only once every two days if you're having issues with inflammation (it's what I do).
However, for EVERYBODY, this product will decelerate aging on the skin. It's so powerful and I look forward to 20 years from now when I look younger than all my friends. HAH!
There is one very important thing I do which no one else has mentioned on here. Since it takes me about a year to finish a bottle of C E Ferulic, I keep it refrigerated. When I order it, I make sure it is almost completely clear (if not then return it). Even after a year of being refigerated, it only turns light yellow. This means that the refrigeration is preventing oxidation of the product and allowing it to stay effective.
Supposedly, "yellow" product is still effective but I really think that the clearer the product is, the better. My dermatologist even recommended that I return a bottle to a vendor one time because he thought the product looked oxidized. When I received my replacement, it was crystal clear.
