Salicylic Acid, More Than Just Antibacterial Support!
January 10 2023 – Shannon Esau
We know it as a superb exfoliant and essential component to the treatment of acne skin, but did you know that salicylic acid is also an analgesic and pain reliever?
Before skin care professionals used it for cosmetic purposes, salicylic was used by Greek physicians to ease headaches and pains. Its uses in medicine date back to 5th century BC and it has been used throughout history to relieve aches, reduce fever, and in some cases as an anti-inflammatory. In fact, this wonder ingredient is noted throughout history among different cultures including Native Americans, Germans, French and English, and it plays a very significant role in plant growth and development.
The name salicylic is derived from the Latin word Salix, which literally translates to willow tree – the bark from which this ingredient was originally obtained. It is a monohydroxy benzoic acid, a type of phenolic and beta hydroxy acid (BHA) that occurs naturally in wintergreen leaves, licorice, marigold, sweet birch, willow bark extract and several other plant species.
In plants it fills a critical role in the growth and development, photosynthesis, transpiration, and ion uptake and transport. It also aids in endogenous signaling, supporting the plant in its defenses against pathogens.
How it Works on the Skin
In the world of skin care it has been used in the treatment of acne, psoriasis, calluses, keratosis pilaris, and warts. Salicylic, a beta hydroxy acid (BHA), works as a keratolytic agent causing cellular turnover, unclogging pores and neutralizing the bacteria within, then essentially constricting the pore size to prevent future clogging. It also stimulates new cell growth.
Salicylic acid has a larger molecule size than its cousin alpha hydroxyl acid, which enables the acid to stay on the surface of the skin allowing it to more effectively, penetrate and exfoliate within the pore. Once it has penetrated the pore it also acts as a chemical trap for free radicals, essentially exfoliating from the inside out. This characteristic makes it a superb exfoliant for acne and acne-prone skin. The larger molecule size also produces less irritation than AHAs, making it a welcome alternative for sensitive skins.
- Provides anti-inflammatory, antiseptic, fungicidal, antioxidant and bactericidal benefits.
- Exfoliates, rejuvenates and supports cell turnover.
- Decreases the skin’s thickness and softens comedones.
- Great for sensitive, rosacea, acne-prone and problematic skins.

Tips When Introducing Salicylic Acid
While this acid is known for its anti-inflammatory properties it is important to be mindful of any changes in the skin including dryness or occasional flaking, especially when you introduce a toner or corrective. We recommend easing into these products, typically using them 2-3 times per week or as directed.
