在beta羟基酸和阿尔法羟基酸之间的区别

您大概听说羟基酸’好处剥皮。 什么您不可以知道是有羟基酸的二个类型- 阿尔法羟基酸 (AHAs),经常指果子酸-和beta羟基酸(丁基羟基苯甲醚),其中只有一个,柳酸。 在这篇文章我们看羟基酸的两个类型帮助您确定他们是否将有益于您的皮肤。

关于阿尔法羟基酸

阿尔法羟基酸(经常指AHAs)从果子和糖获得。 他们包括:

  • 乙醇酸,获得从甘蔗
  • 乳酸,获得从牛奶
  • 扁桃酸从苦杏仁获得
  • 酒石酸,获得从葡萄
  • 苹果酸从苹果和梨获得

在其他之中。

AHAs的主函数将剥落或取消皮肤顶层允许更新,更加健康的皮肤细胞通过显示。 他们是特别有用的在提高太阳损坏的皮肤出现,并且也许帮助减少皱痕出现。 研究表示, AHAs也许也帮助刺激胶原生产。 他们经常是所有皮肤孕腹轻松养生之道一个重要组分。 

AHAs最好用于胶凝体,提取乳脂或者化妆水允许产品提供好处。 洗涤和清洁剂,在AHA可能施加它的行动之前,经常去除。 研究表示, AHAs工作以集中至少4%最好公式化了在酸碱度大约3或4。

关于beta羟基酸

只有从乙酰水杨酸或者阿斯匹灵-柳酸-获得的一beta羟基酸。 象AHAs, beta羟基酸(丁基羟基苯甲醚)作为exfoliant增加死的皮肤细胞流出允许更新,更加健康的皮肤细胞通过显示。

研究显示丁基羟基苯甲醚减少皱痕出现,改进皮肤坎坷和协助减少皮肤染色混乱。 丁基羟基苯甲醚也是极端有用在断裂的治疗和有用的在角化症pilaris,介入封锁的或被堵塞的毛孔的情况管理。

和与AHAs,当选择丁基羟基苯甲醚产品,您可以通过选择有益于更多时在您的皮肤停留的奶油、化妆水或者胶凝体。 在他们有一个机会提供好处之前,洗涤和清洁剂从皮肤被去除。 寻找包含至少1%丁基羟基苯甲醚的产品在酸碱度在3或4之间为了获得最大好处。

The Difference Between Alpha Hydroxy Acids and Beta Hydroxy Acid

AHAs are water soluble so they do not penetrate well beneath the skin’s surface.  They are ideal for use on skin that is not prone to breakouts. BHA, on the other hand, is a lipid (oil) soluble molecule. This characteristic allows BHA to penetrate pores that contain sebum (oil) and help to exfoliate the pore itself. This makes BHA particularly useful in oily, acneic skin prone to breakouts.

Side Effects of Beta Hydroxy Acid and Alpha Hydroxy Acids

Because both BHA and AHAs remove the skin’s top layer, they make skin more sensitive to sun exposure. Sensitivity can increase by up to 50%, which makes the use of broad spectrum UVA/UVB blocking sunscreen with a minimum of SPF 30 a must. Both types of acids can cause irritation including redness, burning, pain or itching. Darker skinned individuals may also be at risk for scarring with the use of AHAs or BHA.

Formulations That Work

If the idea of incorporating an AHA or BHA into your skin care regimen appeals, consider the following products which have been shown to demonstrate benefits in many skin types:

  • MaMa Lotion - mandelic acid and malic acid to deliver benefits to acneic skin as well as melasma
  • LacHydrin - 12% lactic acid to assist in management of dry skin
  • La Roche Posay Effaclar K or Effaclar AI - formulated with LHA, a derivative of salicylic acid to help minimize breakouts
