Target Skin Concerns


Salicylic Acid:
  • Mechanism: Salicylic acid is a BHA that works by:
    • Exfoliating: It loosens dead skin cells and unclogs pores, preventing future breakouts and reducing the size of existing ones.
    • Anti-inflammatory: It can calm redness and inflammation associated with acne lesions.
    • Sebum regulation: It helps control excess oil production, a contributing factor to acne development.
  • Effectiveness: Salicylic acid is generally considered more effective in directly treating acne due to its combined actions. However, it’s important to choose the right concentration and frequency to avoid irritation.
Hyaluronic Acid:
  • Mechanism: While not directly addressing acne, hyaluronic acid can play a supportive role:
    • Post-inflammatory hydration: After acne lesions heal, dryness and irritation may occur. Hyaluronic acid can help replenish moisture and promote faster healing.
    • Barrier strengthening: By keeping skin hydrated, hyaluronic acid can contribute to a stronger skin barrier, potentially making it less susceptible to future breakouts.


Salicylic Acid:
  • Potential impact: Salicylic acid can be drying, especially at higher concentrations or with frequent use. This can worsen dryness and exacerbate existing concerns like flaking and irritation.
Hyaluronic Acid:
  • Mechanism: Hyaluronic acid excels in addressing dryness:
    • Humectant properties: It attracts and retains water in the skin, providing intense hydration.
    • Plumping effect: By drawing moisture into the skin, hyaluronic acid creates a plumper and smoother appearance.


Hyaluronic Acid:
  • Mechanism: Hyaluronic acid offers benefits for aging skin:
    • Hydration: As skin ages, hyaluronic acid levels naturally decline, leading to dryness and wrinkles. Supplementing with hyaluronic acid can counteract this by plumping and hydrating the skin.
    • Fine lines and wrinkles: By keeping the skin hydrated and plump, hyaluronic acid can help reduce the appearance of fine lines and wrinkles.
Salicylic Acid:
  • Potential benefit: While not directly targeting wrinkles, salicylic acid might indirectly contribute to anti-aging:
    • Cell turnover: Salicylic acid can promote exfoliation, encouraging the removal of dead skin cells and stimulating the production of new ones. This may contribute to a more youthful appearance, although research is still ongoing.

Sensitive Skin

Hyaluronic Acid:
  • Gentleness: Generally, hyaluronic acid is well-tolerated by most skin types, including sensitive skin. However, choosing products free of fragrance and other potential irritants is still advisable.
