This product provides both UVA and UVB protection. But SPF 20 is not enough for daily protection. Dermatologists usually recommend SPF 30.
The main effective ingredient retinol is the primary naturally occurring form of vitamin A. Vitamin A is a cell-communicating factor that maintains the normal function of skin cells. It enhances dry or damaged skin by reducing flaking and restoring suppleness. Vitamin A is also potent antioxidant that prevents aging. But how effective it is towards set-in wrinkles has not been proved. For this I found the name "deep wrinkle" hard to justify.
Another effective ingredient is sodium hyaluronate which is the sodium salt of hyaluronic acid. Hyaluronic acid is a natural component of skin tissue that is used in skin-care products as a good water-binding agent.
The ingredient of concern is that this product contains triethanolamine (TEA) which has the potential to turn into an extremely potent carcinogen called nitrosodiethanolamine (NDEA). That means it causes cancer. Even more concerning, NDEA is easily absorbed through skin. There is no way of knowing if the concentration of TEA in this product is high enough to be of concerns.
