salicylic acid

We’re excited for our latest launch: Naturium Bodycare. Because at Naturium, we believe skincare doesn’t stop at your neck. The Perfector Salicylic Acid Body Wash helps exfoliate and smooth rough, bumpy skin. It’s the perfect body cleanser for those pesky problem areas and winter skin blues. But does salicylic acid work in a rinse-off? Read more to learn about the technology and delivery system used in our body wash.

THE SCIENCE BEHIND IT…
OVERALL CLINICAL DATA ON SPECIFIC INGREDIENT(S) & HOW THEY FUNCTION:

There are several obstacles in formulating a rinse-off product with salicylic acid. First, free salicylic acid has limited solubility. This hydrophobicity is perfect for skin allowing it to work inside the pores, clearing excess sebum and debris, resulting in reduced skin congestion and pore size. However, limited water solubility makes it difficult to incorporate into water based systems such as a body wash without first solubilizing with alcohol or excessive neutralizing with a base. Second, free salicylic acid tends to have some irritation potential as it is delivered to the skin all at once, dropping the pH of the skin. Skin pH can often act as an indicator for possible irritation potential of a product. Not only can the free salicylic acid cause irritation but anionic surfactants in a low pH system to reduce the charged state of the salicylic acid can further increase irritation. Low pH means the keratin in the skin becomes more positively charged and this acts as a magnet to negatively charged anionic surfactants which then bind to the stratum corneum and cause protein denaturation and irritation visible as skin dryness and redness. Dryness and stripped skin is already a concern due to cleansing surfactants in a body wash so the addition of free salicylic acid can compound this dryness. Third, and finally, deposition of active ingredients in a rinse-off product is difficult due to low contact time, mechanical friction from rubbing, and dilution from water during rinse-off.


Our Customized Efficacious Cosmetic Version.



Our Salicylic Acid Body Wash utilizes a unique delivery technology that overcomes these obstacles for enhanced exfoliation revealing visually poreless, clearer looking skin. Our delivery system is composed of sub-micron spheres between 0.1-0.3 microns in which the salicylic acid is enclosed. The lipid core contains a skin-like lipid blend that encapsulates the salicylic acid. Alcohol solubilization and base neutralization are not needed. This lipid core is then encased in a polymer shell that allows for suspension in a water based system, pH independent efficacy, and improved adherence to the skin.The spheres adhere to the skin where the hydrophobic matrix gradually breaks down and releases the salicylic acid in a controlled manner delivering the acid to the skin effectively and without irritation. This slow extended release maintains a skin-friendly pH, minimizes skin dryness, and mitigates irritation. Our cleanser delivers 0.5% salicylic acid in a way to minimize loss from water dilution, mechanical rubbing, and low contact time. Coupled with extended release, the salicylic acid is more available for a longer time while being suitable for sensitive skin. An in vivo study showed that this innovative delivery technology can enhance deposition of salicylic acid to the skin three times more effectively than a body wash with free salicylic acid. This resulted in higher efficacy without stressing the skin’s natural pH-buffering system.


Our sub-micron technology-based encapsulation provides gentle exfoliation to smooth skin without dryness or irritation. Blended with skin softening glycerin and linoleic-rich oils for a soft and smooth finish. Our skin renewing body wash, formulated at pH 5.3-6.0, is a gel format with mild lather from gentle surfactants that won’t strip the skin. Developed for all skin types and appropriate for daily use. It is gentle enough for sensitive skin and can also be used as a facial cleanser.
