Natural salicylic acid: the search for natural alternatives in exfoliation

Salicylic acid occurs naturally in several plants, most notably willow bark (Salix alba), meadowsweet, and wintergreen. In cosmetic formulations, plant-derived AHAs — such as fruit acids from apricot extract — offer similar exfoliating effects without the irritation risks associated with salicylic acid in sensitive skin.

Guided by a growing interest in natural, clean beauty products, consumers are increasingly informed on each ingredient’s potential to enhance their skin health. In such a context, salicylic acid has become one of the best-known ingredients for exfoliation, due to this substance’s potential to reach the innermost layers of the skin.

Taking these trends into account, we analyze the role of natural salicylic acid in a beauty market dominated by demands for effective natural ingredients and what the best natural alternatives for this ingredient are.

What is salicylic acid and where is it found naturally?

Derived from a plant hormone and part of salicylates, its chemical composition means salicylic acid is an oil-soluble substance. This characteristic, when applied to beauty and personal-care products, means salicylic acid is able to penetrate further into the skin’s pores and through the lipid layers. This, in turn, makes salicylic acid an exceedingly efficient ingredient for a number of skin care treatments: 

• It presents anti-inflammatory and antimicrobial properties
• Its exfoliating effects are based on this ingredient’s capacities to loosen and break down skin cells. This process helps remove dead cells and, as a result, skin becomes more elastic and polished
• Salicylic acid in natural products is also effective on preventing hyperpigmentation and freckles
• This substance is appreciated for its anti-acne performance: penetrating into pores, it then unclogs them and eliminates skin debris. As such, it’s a common ingredient for products targeting the removal of acne-related issues such as blackheads and whiteheads.

Salicylic acid itself doesn’t exist as such in plants — instead, willow bark extract (INCI: Salix Alba Bark Extract) contains salicin, a glycoside chemically related to salicylic acid — but unlike oral ingestion, topical application does not reliably convert salicin into salicylic acid, since the skin lacks the enzymes needed for that conversion. Its benefits come instead from salicin’s own anti-inflammatory and antioxidant properties (Jeon et al., 2023).

Why are cosmetic formulators looking for natural alternatives to salicylic acid?

While synthetic salicylic acid has been a well-known ingredient in the BPC market, the shift of consumer demands towards ingredients with a natural origin has compelled brands and laboratories to search for natural ‘salicylic acid-like’ solutions.

A majority of consumers today value a beauty brand’s efforts for offering products where natural ingredients are prioritized. While this is a growing trend across all age groups, younger generations are typically more interested in natural ingredients.

At the same time, this search for natural source of salicylic acid for skin coincides with other consumer behaviour trends shaping the current post-pandemic BPC market.

On the one hand, it’s also part of consumer’s growing focus on product ingredients, as the effectiveness perceived and demanded by the consumer is increasingly focused on ingredients.

On the other hand, brands are also being compelled to balance natural ingredients with science-based effectiveness. 

As a result, these concurrent trends have also led to the growing focus on other effective ingredients that go beyond natural salicylic acid, such as the use of fruit citric acids in skin care.

What natural ingredients can replace salicylic acid in exfoliation?

Because of salicylic acid’s abilities to reach the innermost layers of skin, it can be potentially overused and cause issues for sensitive skin, such as dryness, excessive peeling or irritation. 

As a result, brands looking to add effective exfoliation products to their catalogues that tap into natural and clean trends should look into alternative active ingredients. While fruit extracts such as Provital’s apricot extract don’t contain salicylic acid, they’re also relevant sources for the same exfoliating and renovation effects.

Acid	Type	Primary effect
Malic acid	AHA	Mild exfoliation, hydration
Citric acid	AHA	Exfoliation, antioxidant
Glycolic acid	AHA	Deeper exfoliation (trace amounts)
Succinic acid	AHA (citric cycle intermediate)	Anti-inflammatory support

More specifically, the science behind this active ingredient’s powerful cell regeneration possibilities is based on the same exfoliating action as salicylic acid, since they are allα-hydroxy acids (AHA). These acids act at the stratum corneum level, making it thinner and improving skin flexibility while promoting exfoliation processes (Tang et al., 2018). 
All in all, this natural apricot extract provides an effective alternative to natural salicylic acid with the potential to target ingredient-focused consumers looking for plant-based natural skin care products.

Compared to synthetic salicylic acid, natural alternatives like apricot-derived AHAs generally offer shallower penetration and a gentler exfoliating action, making them better suited for sensitive skin types. Unlike salicin-based willow bark extract, fruit AHAs don’t rely on enzymatic conversion, offering more predictable results in formulation.
