BIOCHEMICAL COMPOSITION

Salicylic acid is a phenolic beta-hydroxy acid. In cosmetics, its small size allows it to easily penetrate the epidermis. Its anti-inflammatory properties attracted the interest of chemists early on, though they modified it due to its unpleasant taste. This resulted in a new molecule, acetylsalicylic acid, better known as “aspirin.”

TRACEABILITY & SUSTAINABILITY

The plant-based salicylic acid used at Aroma-Zone is extracted from black willow bark.

Plant-based salicylic acid is a natural compound found in several plants, including willow and meadowsweet. With its exfoliating action, it unclogs pores, regulates excess sebum, and reduces skin imperfections. Skin imperfections, such as dark spots or marks left by old blackheads, are reduced, and skin texture is refined. Another benefit is that exfoliating the skin’s surface cells stimulates epidermal regeneration: collagen levels increase and wrinkles are reduced.

Salicylic acid also possesses anti-inflammatory activity thanks to its inhibitory effect on cyclooxygenases, enzymes involved in the synthesis of inflammatory mediators. This property gives it soothing effects that are particularly valued for relieving the discomfort and tightness associated with blackheads. However, since this effect is primarily intended to support skin comfort, it is not recommended to use this active ingredient on extremely sensitive skin. 

Subjects with mild to moderate acne who used a cleanser containing 2% salicylic acid for 8 weeks saw their blemishes decrease without any drying effect. The treatment is effective and well-tolerated.

A Note from Adeline Nalin, Head Pharmacist and Toxicologist at Aroma-Zone

“The use of salicylic acid derived from black willow (Salix nigra) is considered gentler than synthetic salicylic acid. In fact, black willow does not naturally contain “pure” salicylic acid but rather natural salicylates (salicin and derivatives), which are precursors to salicylic acid. These precursors are less irritating. Salicylic acid derived from black willow thus has a gentler, more moderate action and is therefore better tolerated. Since its action is gradual, the skin barrier remains more stable and the risk of reactions (such as irritation and redness) is reduced. The impact on the skin barrier is thus more gentle.”

A Note from Our Aroma-Zone Toxicologist

“Black willow extracts are often better tolerated than pure salicylic acid; however, people allergic to salicylates or aspirin should avoid it. Even though plant-based salicylic acid is well-tolerated, particularly by sensitive and acne-prone skin, it remains a powerful active ingredient that should be introduced gradually by adjusting the dosage, especially during the first use. Salicylic acid itself also has keratolytic properties; although it is gentle, it is advisable not to use it at the same time as other exfoliating products to avoid a cumulative effect that could weaken the skin barrier. It should be used with caution on highly reactive skin. Its use is restricted to adults and adolescents aged 12 and older.”

A Note from the Dermatologist

“Thanks to its keratolytic properties, salicylic acid helps dissolve sebum and dead skin cells, thereby reducing pimples, microcysts, and blackheads. It is therefore perfectly suited for oily or blemish-prone skin. For best results, start by gradually introducing it into your routine, preferably in the evening, 2 or 3 days a week, and don’t forget to apply sunscreen the next morning.

A few points to keep in mind. Don’t overdo it: using it too often can dry out your skin. Avoid mixing it with other exfoliants to prevent any risk of irritation. Salicylic acid is not recommended for pregnant women or for dry or irritated skin.”

Salicylic acid is regulated in Europe, with a limit of 2% in leave-on skincare products. This is the concentration used at Aroma-Zone to ensure its keratolytic effect. It is also used at lower concentrations in certain formulas for its antimicrobial properties.

Our salicylic acid is derived from black willow bark. This plant-based form has an interesting characteristic in formulations: it naturally provides viscosity, eliminating the need for unnecessary gelling agents and resulting in a stable and effective texture.

It is suitable for combination to oily skin, blemish-prone skin, dull skin, and damaged skin.

For oily skin

Salicylic acid is particularly effective at regulating excess sebum, unclogging pores, and preventing the appearance of blackheads and comedones. It helps mattify the T-zone and reduce shine, for a clearer, more even complexion.

For acne-prone skin

Thanks to its purifying and soothing properties, it helps reduce blemishes and calm acne-related redness. Used regularly, it promotes better skin balance and gradually reduces inflammation.

For combination skin

The active ingredient helps balance oily areas (forehead, nose, chin) while gently exfoliating drier areas. It provides a smoothing effect and evens out skin texture without drying it out.

For thick skin or skin with enlarged pores

By removing dead skin cells, it refines skin texture and visibly reduces the appearance of enlarged pores. The complexion looks more even, and the skin becomes softer and more radiant.

For sensitive skin

Although it is gentler than other exfoliants, this active ingredient should be used with caution on sensitive skin: preferably at a low concentration and avoiding frequent use. It is important to monitor the skin’s tolerance before gradually increasing the frequency of use.

The skin concerns addressed include blackheads and comedones, excess sebum, lack of radiance, uneven skin tone, and hyperpigmentation spots.

It purifies the skin and unclogs pores, helps eliminate blackheads, reduces blemishes, minimizes uneven skin tone, stimulates skin regeneration, and leaves the skin smoother and softer.

In fact, this active ingredient offers multiple benefits: 

• Gentle exfoliation: it removes dead skin cells from the skin’s surface and promotes cell renewal

• Deep-cleansing action: by purifying the pores, it helps limit the buildup of sebum and impurities

• Prevention of blackheads: it reduces the formation of comedones and helps maintain healthier, more balanced skin

• Sebum regulation: it balances sebum production, helping to prevent excess shine and blemishes

• Purifying action: helps limit the bacterial growth responsible for skin imperfections

• Supports cell renewal: it promotes epidermal regeneration for smoother, softer skin

• Improved skin texture: helps refine skin texture and restore radiance and evenness to the complexion

• Correction of irregularities: it helps fade pigment spots, fine lines, and minor surface imperfections.
