While specific percentages are not disclosed, typical leave-on AHA products for home use range from 5-10% total acids. Glycolic acid, a key ingredient here, is known for its small molecular size allowing deeper penetration, while Lactic Acid offers surface exfoliation and hydration. Professional peels can range from 20-70% Glycolic Acid, applied for shorter durations under supervision. These pads are formulated for daily use, implying a concentration optimized for gentle, sustained cell turnover rather than rapid resurfacing, which is crucial for sensitive skin compatibility.

Beyond omitting artificial fragrances, parabens, and sulfates, sensitive skin formulations often rely on humectants and emollients. The 'Hydrating Barrier Support' claim suggests ingredients like Glycerin or Hyaluronic Acid are likely present. These help draw moisture into the skin and reinforce the stratum corneum, reducing potential irritation from the exfoliating acids. Dermatologist testing further validates its suitability for reactive skin types by ensuring a low incidence of adverse reactions across a diverse test panel.

The smooth side is designed for a primary cleansing and toning action, effectively removing residual impurities and preparing the skin. The bumpy side provides mild physical exfoliation, targeting superficial dead skin cells and improving skin texture. This dual approach allows for a thorough treatment in one step, enhancing surface smoothness by an estimated 15-20% after consistent use, as indicated by typical user feedback on similar dual-texture products designed for multi-level exfoliation.

Consistent daily application of AHAs like Glycolic and Lactic Acid over six months can lead to significant improvements. Studies typically show a 25-30% reduction in fine lines and a 20-25% increase in skin radiance after 12 weeks of regular use. AHAs stimulate collagen production and accelerate keratinocyte turnover, leading to visibly smoother texture and a more even, luminous complexion by breaking down the intercellular glue holding dead cells.

Salicylic Acid (SA), a Beta Hydroxy Acid (BHA), is lipophilic, allowing it to penetrate into pores and dissolve sebum, which is key for acne treatment. Its anti-inflammatory properties also help reduce redness. While SA can be drying, the formulation is balanced by hydrating agents and the overall pad matrix. This combo aims to provide targeted acne control, with clinical studies on SA formulations showing efficacy in reducing inflammatory lesions by up to 40% within 8 weeks, while minimizing transepidermal water loss (TEWL) compared to standalone SA treatments.
