Our most effective retinoid formula with stabilized retinaldehyde for use in advanced age, ideal for use at night. Retinal 0.2% Emulsion is a highly effective retinoid formula that quickly firms and smoothes the skin while visibly reducing age spots. It helps to refine the skin structure, at the same time counteracts an uneven skin tone and improves the radiance of the skin. The serum is suitable for all skin types and is recommended for experienced retinoid users. For first-time retinoid users, we recommend trying Granactive Retinoid 2% Emulsion or Retinol 0.2% in Squalane and moving on to higher concentrations as skin tolerance improves. Retinal (also known as retinaldehyde) is a well-studied retinoid that offers a more efficient delivery of the most direct form of vitamin A molecules than retinol, as it is closer to the bioactive form of vitamin A. With a high concentration of 0.2% retinal, Retinal 0.2% Emulsion is able to noticeably improve skin firmness and improve the appearance of expression lines and wrinkles, such as crow's feet, frown lines and forehead wrinkles. Retinal 0.2% Emulsion also contains synthetic oat analogues (particularly avenanthramide - an important component of oats). The ingredient is known to help with skin discomfort and dryness that often occurs with the use of retinoids. The formula's bright yellow hue is due to the high concentration of retinal, which is naturally yellow. This may leave some residual color on skin and light-colored fabrics. This can be minimized by allowing the product to fully absorb and allowing the skin to dry before contact with light-colored fabrics. This color residue can be removed by washing the skin with water and washing fabrics with your normal laundry detergent according to the care instructions.
