Tretinoin

Retinoids - but Not all retinoids  are equal

Tretinoin a first generation Vit A which falls into  a group called retinoids. It is only available on prescription &  marketed as Retin A, Retrieve, Stieva A
I’m a big Tretinoin (Retrieve RetinA Stieva A) fan, because of its many actions on the epidermis/demis. 
Tretinoin ( Retin A Stieva A Retrieve) should not be confused with non prescription  retinols that require conversion to tretinoin to achieve the same result. Unfortunately during the conversion these retinols loose much of their potency!

Tretinoin has a number of favorable actions on the epidermis. Tretinoin modifies epithelial cellular growth,exfoliation and inhibits the first stage of acne -microcomedo ( white head ) formation
Additionally
  •     Controls oil secretion and therefore a long term treatment for acne
  •     Enhances vascularity of the dermis
  •     Reduces pigment production
  •     Increases production of glycoamino-glycans. The natural skin moisturiser
What are the essential tips for correctly using Tretinoin in your skin care routine?
Tip #1: The action of Tretinoin is enhanced by combination with the NU-Derm System

Tip #2:  Tretinoin goes on at night.
Tretinoin is light sensitive so apply it at night before retiring. Wash it off in the morning then apply your other skin care products.

Tip #3:  Some ingredients will interfere with Tretinoin.
Don’t mix glycolic acid, vitamin C, benzoyl peroxide, or salicylic acid with tretinoin cream. (Retin A Micro is less fragile, but it’s not my favorite product for anti-aging because all the really pivotal anti-aging studies were done on the cream formulation.)

You can still use these ingredients but apply them in the morning after washing off the tretinoin you applied the night before.

Tip #4:  Skin has to be totally dry before you apply Tretinoin.
Apply compatible products first, one right after the other, then wait 15 minutes or more before applying tretinoin. This lets the excess surface water evaporated from your skin, and that seems to matter for minimizing tretinoin-induced skin irritation. It means that if you are using products those products are applied right after washing. Wait 15 or more minutes, then apply the tretinoin. I recommend keeping tretinoin on the bedside table and applying it right before going to sleep

Tip #5:  Tretinoin-treated skin must be sun protected every day.
Tretinoin makes skin more sun sensitive. If you’re going to use it for all the good things you get from tretinoin treatment then you need to be committed to using broad spectrum sunscreen and a hat when you’re in the sun. I

Tip #6:  Work your way up to the highest tretinoin level your skin can tolerate.

Your skin has to be trained to tolerate tretinoin, and more is better meaning you get more benefit from higher strength levels of the medicine. I tell people it’s like a weight training program because you have to start with weights you can lift and slowly, over time, you’ll lift heavier weights as you gain fitness. It’s the same with tretinoin. You start with .025% twice a week and eventually work to 0.05% nightly. 

Warning: Tretinoin Should not be used in females considering pregnancy & during Pregnancy or Breast feeding.
