Science
Mechanism of Action
Hydrolyzed Potato Tuber Extract delivers essential amino acids such as glutamine, asparagine, and arginine, vital for skin health and nourishment. Its rich content of vitamins B6 and C, alongside minerals and antioxidants, provides protection against environmental stressors and free radical damage, strengthening the skin's natural barrier. Components within the extract are theorized to activate PI3K/Akt and MAPK/ERK signaling through TGF-β receptors, which subsequently stimulate type I collagen synthesis by fibroblasts. Ascorbic acid, phenolic compounds, and flavonoids present in potatoes also contribute to collagen production. Natural starches gently absorb excess oil, while natural sugars promote skin renewal, and tannins, flavonoids, and minerals found in the pulp extract help reduce blemishes and enhance skin vitality.

Key findings
- 01 Clinical evaluation of a 10% potato extract in clay masks over 4 weeks demonstrated significant improvements in skin condition: a 45.2% increase in water content, 8% reduction in pore size, 31.9% increase in skin smoothness, 57.37% reduction in blemishes, and 41.8% reduction in wrinkles (Ginting et al., 2020).
- 02 Concentrations ranging from 0.01% to 1% have been recognized for providing hydrating and soothing benefits to the skin (Paula's Choice).
Transparency
Dusting Analysis
Clinical data indicates efficacy at concentrations as low as 0.01% for soothing benefits and up to 10% for significant anti-aging improvements, suggesting it is typically included at functionally effective levels rather than for 'dusting'.
The Formula
Formulation
Stability
The extract exhibits high solubility at pH 2 and pH 8, with reduced solubility around pH 6. Emulsifying activity and stability are enhanced in acidic to alkaline conditions, peaking at pH 10. This broad pH tolerance suggests excellent stability and functional properties across diverse formulations.
Safety
Safety Profile
Formal safety assessments by major regulatory bodies like CIR, SCCS, or FDA specifically for Hydrolyzed Potato Tuber Extract are not documented in current research. However, it is generally considered to have low irritancy.
