Studies suggest comparative efficacy between retinol and plant-based alternatives can be evaluated through transcriptomic analysis and collagen synthesis assays in both 2D and 3D skin models
In our model, serine and glycine in the cell remain constant, as is methionine input (important for the synthesis of cysteine)
The skin is reorganising itself, and that reorganisation is not always quiet
The mechanism involves stimulating over 300 different genes associated with tissue repair and remodeling, fibroblast activation and collagen synthesis, epidermal basal stem cell viability, an anti-inflammatory effect, an antioxidant effect and stimulation of microvascular growth
