Beauty blogging may be a serious passion of mine, and while at weekends I spend my time testing as many beauty products I can get my hands on, during the week I swap my contour brush for a pipette and my makeup belt for a white lab coat.
Whether it be a cleanser, serum or moisturiser, chances are your beauty products contain ingredients that you are just as likely to find in any laboratory. Science is the key behind good skincare.
With that in mind I would like to share my scientific knowledge with you, and over the following week I will be providing insight on some of the most popular science beauty buzzwords.
Buzzword 1: AHAs/BHAs
Alpha Hydroxy Acid (AHA) and Beta Hydroxy Acid (BHA) are two types of acid that are used in skincare products for exfoliation purposes. Their function is to increase cell turnover, encouraging cell growth to leave your skin even and smooth. The main difference between the two, is how soluble they are in oil. AHAs readily dissolve in water, whilst BHAs are oil soluble.
One well-known BHA is salicylic acid. Due to its ability to penetrate oil, salicylic acid is able to get deep into the outermost layer of skin (stratum corneum) to clear blocked pores and is therefore regularly used in treatment of acne-prone skin.
AHAs act as more superficial exfoliants with one of the most popular being glycolic acid. Naturally derived from sugar cane, this hydroxy acid tackles minor hyper pigmentation and aids in cell renewal by sloughing off the top dead layer of skin.
Although they both sound intense, there is no need for concern as they are present in low concentrations in most beauty product you buy from a store. However, if you suffer from sensitive skin, it may be best to limit your usage of AHAs and BHAs to 2-3 times a week as they can cause minor irritation.
