Retinol

Also-called: Vitamin A | Function: Anti-acne, Skin conditioning, Skin brightening, Cell-signaling ingredient

Retinol is a synthetic derivative of Vitamin A and is commonly found in skincare products. It works by increasing cell turnover and promoting the production of collagen, resulting in smoother, refined skin texture and reduced acne breakouts. It also helps fade dark spots and improves the appearance of fine lines and wrinkles. However, pregnant women should avoid using retinol due to potential risks. Side effects may include irritation, redness, dryness, peeling, and burning, but these can be minimized by adjusting usage frequency and using a moisturizer. If symptoms persist or worsen, it's advisable to consult a healthcare provider.

Aqua/water/eau

Also-called: Aqua, Aqua/Water, Water/Aqua/Eau, Aqua/Water/Eau | Function: Skin conditioning, Solvent

Water serves as a fundamental component in skincare products, often listed as the first ingredient, which means it's the most abundant. It acts as a solvent, helping to dissolve other ingredients and facilitate the application and absorption of products.

Glycerin

Also-called: Glycerol | Function: Skin-identical ingredient, Viscosity controlling, Skin protecting, Skin conditioning, Humectant/Moisturizer, Solvent
