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.
Rosacea refers to a redness of the face caused by a condition affecting the blood vessels in the face. It’s more common in middle-aged women with lighter complexions, although rosacea can affect anyone. The exact cause is unknown, though it is typically hereditary and not caused by pore clogs or skin infections. Many people mistake rosacea’s redness and bumpiness of the face for acne. Rosacea has no cure, and it can fluctuate in its severity from month to month.
There are a few ingredients that can help reduce inflammation associated with rosacea. For example, jojoba oil is good for reducing inflammation associated with certain conditions that cause redness. However, it is important to work with a dermatologist to determine the cause of redness on your skin to determine the right course of treatment if it is rosacea or a combination of concerns.
BHA (beta hydroxy acid) may be effective for rosacea, 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.
