Why do you need to apply an SPF whilst using Retinol, Retin-A, Tretinoin, Tanzorac, Tanzorotene?
It is essential to apply SPF sun protection, to protect your skin against harmful sun rays which are UV UVA UVB which are extremely harmful in implementing premature aging & Life-threatening conditions such as skin cancer.
The ultraviolet rays from the sun that penetrate deeply into the skin. damage the skin’s elastic fibres that keep skin firm, allowing fine lines & wrinkles to develop. Sunlight is also responsible for age spots or “liver spots” on the hands, face, and other sun-exposed areas.
Retinol & Retinoids are advised to be used at night as the last product you apply
There are 2 reasons for this ….
If retinol or Retin-A Tretinoin Tanzorac Tanzorotene are exposed to sunlight it decreases the efficiency of the product also retinol & retinoids work by speeding up the process of removing dead skin cells to reveal younger brighter fresher skin cell’s so it is a must you are diligent regarding your sun protection It is advised you use SPF30 or higher I personally use SPF50 Z Block every morning which protects me from UV UVA UVB rays it is a Zinc Oxide physical sunscreen so no harmful chemicals, it is easily absorbed leaves no white cast and is deeply hydrating also it makes for a great primer so you can easily apply your make up afterwards. SPF should be applied every day even during winter as harmful rays are still present and still penetrate the skin through clouds.UVA can also penetrate through glass windows and UVB is the high-energy ray that penetrates and burns the epidermis.
