🧴 Formulations featuring Polygonum Cuspidatum Root Extract

A highly sophisticated, multi-pathway acne treatment serum that goes beyond basic Niacinamide. The Raw balances a clinical 5 percent dose of Niacinamide with a highly calculated acid cocktail (Glycolic Acid and Salicylic Acid). This allows the serum to control sebum, fade post-acne marks, and gently clear clogged pores simultaneously without severe barrier stripping. The immense botanical load (Green Tea, Centella, Licorice) ensures that localized redness is actively suppressed during the chemical exfoliation phase safely.

A highly targeted, single-active focus serum that maximizes the efficacy of Alpha Arbutin by buffering it with an immense botanical soothing complex. The clinical 2 percent concentration of Alpha Arbutin is the optimal dose to inhibit tyrosinase safely without causing cellular toxicity. The inclusion of Licorice and Green Tea works synergistically to suppress the underlying inflammation that often drives post-inflammatory hyperpigmentation (PIH), making this a highly reliable dark spot eraser.

The Raw.

Salicylic Acid 2% Serum

Serum

A masterclass in BHA formulation. The Raw utilizes a true 2 percent Salicylic Acid base at an optimal pH (approx 3.8) to ensure maximum lipophilic penetration without neutralizing the acid. Because BHA can be inherently drying, the formula intelligently offsets the astringent effect with an intense botanical matrix (Centella, Licorice, Green Tea) and Panthenol. This provides aggressive, deep-pore purging power while actively calming the inflammation surrounding painful active pimples.

Ethylated Ascorbic Acid 20% Serum

Serum

A breathtaking achievement in local Vitamin C formulation. Pure L-Ascorbic Acid oxidizes rapidly in tropical heat, turning brown and irritating the skin. The Raw bypasses this by utilizing a staggering 20 percent concentration of 3-O-Ethyl Ascorbic Acid, the most stable and effective Vitamin C derivative available. This allows for clinical-grade collagen stimulation and spot fading without the low-pH acid burn. The massive botanical load ensures the skin remains completely calm while the active vitamin works flawlessly.

A highly sophisticated barrier repair serum that goes beyond basic hydration. The Raw balances a clinical 5 percent dose of Niacinamide with a highly calculated 5-Ceramide complex. This allows the serum to control sebum while deeply patching micro-tears in the stratum corneum safely. The immense botanical load ensures that localized redness is actively suppressed during the healing phase flawlessly.
