SymWhite 377 is comparable to kojic acid but without skin irritation and associated side effects.
SymWhite 377 – Ingredient Overview
SymWhite 377 is a potent cosmetic brightening active (phenylethyl resorcinol) used to help reduce the look of dark spots and even skin tone. It performs at low usage levels and fits well in both face and body formulations.
What research shows
Studies and technical reviews indicate that phenylethyl resorcinol interrupts melanin formation pathways while providing antioxidant protection. As a result, formulators observe measurable improvements in pigmentation and brightness when the active is used consistently in well-designed products. Moreover, mechanistic work supports its role as a strong tyrosinase inhibitor and antioxidant in topical systems.
Additionally, combination trials show enhanced outcomes when SymWhite 377 is paired with niacinamide, alpha arbutin, or vitamin C derivatives. These combinations often yield a more complete brightening effect and improved texture in both facial creams and body lotions.
Benefits
- Supports a brighter, more uniform-looking complexion
- Helps reduce the appearance of dark spots and discoloration

- Effective at low usage rates and stable in many systems
- Pairs well with niacinamide, alpha arbutin, and vitamin C derivatives
Technical information
- INCI: Phenylethyl Resorcinol
- Solubility: Oil-soluble; soluble in glycols and warm oils
- Usage rate: 0.1% – 0.5% standard for leave-on products
- pH stability: Generally stable in pH 4.0–6.5
- Appearance: White to off-white powder
- Storage: Store in a cool, dry, dark place
Formulation notes
Add SymWhite 377 to the oil phase or pre-dissolve in a suitable solvent (glycol or warm oil) before incorporation. In practice, formulators apply gentle heat to aid solubilization, then cool and test stability. Always run full compatibility and stability testing when combining with acids, high electrolyte systems, or oxidation-sensitive actives.
