Retinol is pure Vitamin A that is used to rejuvenate the skin. To provide skin benefits, retinoids (other than Tretinoin) must be converted into retinoic acid.
What are the benefits?
Retinol is a superstar ingredient that has been shown to improve skin radiance and treat symptoms associated with chronological ageing, such as wrinkles and fine lines.
Retinol is very sensitive to air and light therefore packaging a key when choosing a retinol product. Many retinol products have poor packaging and should be avoided because the retinol would most likely be (or quickly) oxidised and become ineffective.
Our Renewal Elixir is packaged in opaque double-walled and airless pump bottles to ensure products remain efficacious during their in-use lifespan.
