Eucerin DERMOPURE Cleansing Gel is a soap- and fragrance-free, non-comedogenic daily face wash designed for blemish- and acne-prone skin.
Understanding Key Skincare Ingredients
The foundation of many skincare products is water, also known as H2O. In cosmetics, the water used is purified and deionized, meaning that almost all mineral ions have been removed. This ensures a pure and effective base for formulations.
Cleansing Agents in Skincare
Several ingredients play a crucial role as cleansing agents. One such ingredient is Sodium Cocoamphoacetate, a clear, yellowish liquid with an amphoteric structure. This means its head possesses both positively and negatively charged parts, contributing to its mildness and excellent foaming properties. Unlike most surfactants, which are anionic (negatively charged heads), Sodium Cocoamphoacetate offers a gentler cleansing experience.
Another common cleansing ingredient is Propylene Glycol. While often confused with Sodium Lauryl Sulfate (SLS), it is distinct. Sodium Laureth Sulfate (SLES), a related compound, has a larger water-soluble head, making it milder and less irritating than SLS. While generally considered safe in cosmetic concentrations, formulas without SLES might be preferable for those seeking exceptionally mild facial cleansers. For typical shower gels, SLES is acceptable.
The Role of Sodium Chloride (Salt)
Sodium chloride, commonly known as salt, is frequently found in the ingredient lists of cleansing products. Its primary function in formulas with ionic cleansing agents (surfactants) like Sodium Laureth Sulfate is to act as a thickener. Adding a small percentage (typically 1-3%) transforms a thin surfactant solution into a desirable gel texture. This phenomenon occurs because electrolytes, such as the Na+ and Cl- ions in salt, reduce the electrostatic repulsion between the head groups of ionic surfactants. This allows for the formation of elongated micelles, which intertwine like spaghetti, creating a gel consistency. Beyond thickening, salt also serves as an emulsion stabilizer in water-in-oil emulsions, where water droplets are dispersed within an outer oil or silicone phase.
Citric Acid: An AHA from Citrus Fruits
Citric acid, derived from citrus fruits, is classified as an Alpha Hydroxy Acid (AHA). However, comparative studies suggest that it possesses fewer skin-improving properties compared to glycolic or lactic acid.
Preservatives in Skincare
Preservatives are essential "helper" ingredients that ensure the longevity and stability of cosmetic products. They prevent spoilage and maintain product integrity over time. Some preservatives, like those that work best at acidic pH levels (3-5), are pH-dependent.
Eucerin DermoPurifyer Triple Effect Serum: Targeted Action
The Eucerin - DermoPurifyer Triple Effect Serum is formulated to address multiple concerns of problem skin, offering benefits such as:
- Evens skin tone
- Anti-blemish action
- Moisturization
- Exfoliation
Key Ingredient: Salicylic Acid
A standout ingredient in this serum is Salicylic acid, present at a concentration of 1.10% - 1.70%. As an oil-soluble exfoliating acid, salicylic acid has the unique ability to penetrate pores, helping to reduce congestion. It also possesses anti-inflammatory properties, making it highly effective in treating acne. Due to its potent exfoliating nature, caution is advised to avoid over-exfoliation, which can lead to skin irritation.
Supporting Ingredients for Skin Health
Panthenol (pro-vitamin B5), found at approximately 0.55% - 1.30% concentration, plays a significant role in improving the skin barrier function and reducing inflammation.
The serum also contains a blend of humectants: pantolactone (0.15% - 0.60%), panthenol (0.55% - 1.30%), and glycerin (3.60% - 5.40%). These ingredients work synergistically to draw moisture into the upper layers of the skin, thereby enhancing skin hydration.
