So I am using a good retinol product if its name is retinol and there is retinol in the ingredient list?
Yes, if the brand provides a clear concentration: 0.5, or 1.0 without any ambiguous terms. Some, though state 0.5% or 1.0%, only infuse a limited amount of retinol due to the cost and the risk of stability. In most cases, less than 0.1% pure ingredient is added. For Hyaestic, we deliver 100% of what the label states. 1.0 retinol means 1.0% pure concentration retinol on the product.
