BHA is an abbreviation for beta hydroxy acid, also known as salicylic acid. Don’t let the word ‘acid’ put you off. BHA is not corrosive or abrasive and actually has soothing properties. Making it much kinder on your skin than scrubs and cleansing brushes.
Salicylic acid is a keratolytic, meaning it dissolves the bonds that hold skin cells together and helps them to shed away more effectively. It's naturally occurring in white willow bark and wintergreen, but most of the salicylic acid used today is synthesized.
Salicylic acid is especially helpful in treating acne because of its ability to penetrate the follicle. It encourages the shedding of dead skin cells from within the follicle, helping keep the pores clear. And keeping the pores clear is the first step in getting all types of blemishes under control. It works best against non-inflamed breakouts, and blackheads.
Salicylic acid has other benefits, too. It helps to decrease oil and inflammation.
Most people can use salicylic acid without any big problems, but people with sensitive skin may suffer from skin irritation when using a high concentration of salicylic acid.
Dry skin, also called xerosis, is when the outer most layer of skin, or epidermis, isn’t retaining sufficient moisture. The epidermis is partially made up of epidermal proteins and fats, or lipids, which help to retain moisture. If the proper amount of these proteins or lipids are lacking, moisture will evaporate more quickly and dry skin will ensue.
Also, external and environmental factors, such as weather, cold air, hot and excessive showers and harsh soaps, are notorious for either causing or exacerbating dry skin.
Rosehip oil enhances the appearance of dry or damaged skin by reducing flaking and restoring the overall vitality of the skin. Jojoba oil is also good for keeping in moisture for healthier skin. Hyaluronic acid is another great ingredient for retaining moisture in dry skin.
Acne-prone dry skin is the hardest to treat because anti-acne ingredients like salicylic acid, glycolic acid, retinoid, etc tend to be drying. Instead of avoiding these effective ingredients, you can combine these ingredients with moisturizing ingredients to counter effect the dryness of these ingredients.
BHA (beta hydroxy acid) may be effective for dry skin, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you.
