Properties and areas of use: Retinyl Palmitate is one of the vitamin A derivatives. A member of the retinoid family, this ingredient is used to improve the appearance of the skin and reduce the signs of aging. It is more suitable for sensitive skin. Retinyl Palmitate is frequently used in anti-aging creams, serums, and night care products. It is formulated to reduce the appearance of fine lines, wrinkles, and sagging skin. It is used in acne treatment as it cleans pores and promotes cell regeneration. It can be found in brightening products used for skin spots and hyperpigmentation. It can be used in after-sun products to repair sun damage and soothe the skin. It helps strengthen the skin's natural barrier and can reduce moisture loss, so it can be found in moisturizing creams and lotions.

Physical Form: Retinyl Palmitate is typically found in the form of a clear or opaque oily liquid or waxy solid, ranging from light yellow to yellow. It has a mild characteristic odor. When in solid form, it melts between approximately 28°C and 33°C. It has a high boiling point. It is sensitive to light and air. Therefore, to maintain its stability, it is usually used in light-proof packaging and with anti-oxidizing agents. Retinyl Palmitate should be stored in a cool and dark environment. It is recommended to store it in airtight containers to prevent oxidation and degradation. To preserve its stability, it is often combined with antioxidants, and special care should be taken during packaging due to its sensitivity to light.

Recommended pH range: The recommended pH range for Retinyl Palmitate to maintain its effectiveness and stability in skincare products is 5.0-6.0. This range is the pH range where Retinyl Palmitate maintains its maximum stability and provides the best results on the skin. Lower pH levels can cause Retinyl Palmitate to degrade, while higher pH levels can reduce its effectiveness.

Solubility: Oil-soluble, but not water-soluble. Retinyl Palmitate is suitable for oil-based formulations.

Function: It protects against oxidative stress by neutralizing free radicals in the skin. This supports a healthier and younger-looking skin. It accelerates the renewal of skin cells. This helps reduce the appearance of fine lines, wrinkles, and rough texture in the skin. It promotes collagen production, increasing skin elasticity. This contributes to a firmer and smoother appearance of the skin. It helps reduce pigmentation, which can even out skin tone and lighten the appearance of dark spots and uneven coloring.

Recommended usage rate: It can be used in anti-aging creams and serums at 0.1-1%; in night creams at 0.2-1%; in eye contour creams at 0.1-0.5%; in moisturizers and lotions at 0.1-0.5%; and in acne treatment products at 0.2-1%. Although Retinyl Palmitate is milder than other forms of vitamin A derivatives, it can still cause irritation in some skin types. Therefore, it is important to start with low concentrations and gradually increase the rate according to the skin's tolerance. Retinyl Palmitate can increase the skin's sensitivity to the sun. Therefore, if used during the day, it is recommended to use it with a broad-spectrum sunscreen.
