Basic Knowledge of Skin care Formula Development
Skin Structure and Types Skin Structure: The skin, the largest organ of the human body, consists of three main layers: Epidermis: The outermost layer, including the stratum corneum, primarily serves protective and barrier functions. Dermis: The middle layer contains collagen, elastic fibers, and blood vessels, providing elasticity and support. Subcutaneous Tissue: The deepest layer, composed mainly of fat and connective tissue, acts as cushioning and protection.
Skin Types: Based on sebum secretion and moisture content, skin can be categorized into the following types: Dry Skin: Characterized by dryness, lack of oil, prone to flaking and fine lines. Oily Skin: Excessive sebum production, prone to acne and clogged pores. Combination Skin: Oily T-zone (forehead, nose, chin) with dry areas on the cheeks. Sensitive Skin: Easily irritated by external factors, prone to redness, itching, and allergic reactions.
Classification of Formula Ingredients Base Ingredients: Water: The most common base ingredient, used to dissolve other ingredients and provide moisture. Oils: Such as plant oils and mineral oils, providing nourishment and hydration. Emulsifiers: Help mix oil and water to form a stable emulsion. Thickeners: Adjust the consistency of the product, like xanthan gum and carbomer.
Active Ingredients: Humectants: Such as hyaluronic acid and glycerin, attract and retain moisture. Antioxidants: Like vitamin C and vitamin E, fight free radicals and slow skin aging. Whitening Agents: Such as arbutin and niacinamide, inhibit melanin production and brighten skin tone. Anti-Aging Ingredients: Like retinol and peptides, promote cell renewal and reduce wrinkles.
Preservatives and Stabilizers: Preservatives: Such as phenoxyethanol and potassium sorbate, inhibit the growth of bacteria and mold. Antioxidants: Like vitamin E and BHT, prevent the oxidation of oil ingredients in the product.
Auxiliary Ingredients: Fragrances: Provide a pleasant scent. Colorants: Such as titanium dioxide, used to adjust the product color. Stabilizers: Like EDTA, maintain the stability of the formula.
