Do you know your alphas from your betas?
Our skin naturally sheds cells every day, but this natural process can slow down for a number of reasons – from dry skin to genetics.
The result can be dry, dull, or constipated skin that needs a little help to get moving again. And this is where acids can come in!
Although they sound scary, especially on sensitive skin types, carefully controlled levels of these fruity acids can help the skin to rebalance.
Alpha-hydroxy acid (AHA) are water-soluble acids that are obtained from natural substances such as sugar cane, grapes and milk – although nowadays most acids are obtained synthetically to control their strength. They often appear in skin care as glycolic, lactic and malic acids.
These acids melt the "glue" that holds dead skin cells together on the surface of the skin. They exfoliate the skin without grainy peels to leave a lighter, smoother finish.
We use an ultra-gentle form of Pink Pomelo AHAs in our Copaiba Deep Cleanse AHA mask to give this silky clay mask a peeling boost.
In contrast, beta-hydroxy acid (BHA) are oil-soluble acids. This means that they are absorbed into the natural oils of our skin and can get directly into the pores. This makes them a popular choice for removing blackheads and traffic jams.
BHAs are said to have anti-inflammatory and antibacterial properties and are often recommended for skin prone to redness. One of the most common BHAs; Salicylic acid can aggravate and dry sensitive skin – so be careful!
