Tea Tree Oil Pimple Cream
Aiken
Tea Tree Oil Pimple Cream
Treatment

A highly reliable botanical spot treatment. It utilizes a dense base of Lactic Acid and Phytosphingosine to provide a thick cushion that targets active breakouts. By incorporating pure Tea Tree Oil, it actively neutralizes the infection without requiring harsh synthetic chemicals.

Vita-C Bright Exfoliating Water
Aiken
Vita-C Bright Exfoliating Water
Toner

A highly functional hybrid acid toner. It merges the gentle chemical exfoliation of Lactic Acid and Mandelic Acid with the pore-clearing power of Salicylic Acid. By buffering these acids with Betaine and Panthenol, it successfully refines skin texture without destroying the moisture barrier. The inclusion of Ascorbyl Glucoside and Niacinamide provides a rapid brightening effect for dull profiles.

Rohto Mentholatum
Melano CC Vitamin C Brightening Essence
Essence

The absolute undisputed viral king of dark spot fading in Malaysia. While standard water-based Vitamin C serums decompose within weeks under Malaysia's tropical heat and change into an amber brown oxidized color, Rohto utilizes a revolutionary, completely waterless (anhydrous) glycol delivery vehicle. This encapsulates the pure L-Ascorbic Acid molecule flat, guaranteeing absolute 100% stability without degradation for up to a year. It integrates Isopropyl Methylphenol (O-Cymen-5-Ol) to sterilize active pore systems. The texture is a uniquely slick, dry oil-like fluid that warms slightly upon facial contact, drying into a comfortable velvety layer.

Niacinamide 5% Serum
The Raw.
Niacinamide 5% Serum
Serum

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.

Vitamin C Brightening Essence
Rohto Melano CC
Vitamin C Brightening Essence
Essence

A absolute masterpiece of pharmaceutical formulation chemistry from Rohto Japan. Standard Vitamin C (Pure L-Ascorbic Acid) is notoriously unstable and oxidizes into a useless orange fluid within weeks when exposed to air. Melano CC completely bypasses this by using an anhydrous (water-free) glycol base combined with a patented airless gray nozzle tip that dispenses the product drop-by-drop. It stays clear and active for over a year. The formula behaves like a slippery dry-oil on application and drives the Ascorbic Acid deep into hyperpigmented lesions with unparalleled stability.
