Should I Start with the Lowest Dose of Retin A if I Have Never Used It Before?

Yes when first starting Retin-A it would be beneficial for you to start at a lower dose and work your way up, this will help minimize the negative side affects such as redness, dryness, or irritation,  You may also think about starting at Retinal - which is a milder version of Retin-A.  Keep in mind what other medical grade skin care products you are using, you don't want to over due it and end up stopping your products do to irritation,.  I would recommend starting every other night and working your way up. 

Starting with the lowest dose of Retin-A and working your way up to a higher dose is definitely a good idea. Doing this may minimize the redness, dryness, and irritation that is a common side effect of Retin-A, especially when beginning a routine. Start at 0.05% and use it every other night if irritation develops. Everyone's skin adjusts differently to Retin-A so adjust how often and what percentage that you use slowly until irritation is minimal-and get a good moisturizer and sunscreen for use during the day!

Retin A is used for acne and for photodamage.  Acne skin tends to be more oily, although not always, and photodamaged skin tends to be more dry.

For oily skin, you can start with a mid-dose of Retin A of 0.05% and increase from there.  For dry, photodamaged skin you want to start at the lowest dose.

The lowest dose of tretinoin is actually in Renova at 0.02%.  Renova is a relative of Retin A that has a moisturizer in it.

Start the applications twice a week at nighttime, using a pea-size amount of the Retin A to be applied to the entire face avoiding the eye area.  Before the application wash your face with a mild cleanser and let the skin dry for 15 minutes.

If you still find that your skin is getting dry, you can apply a moisturizer made for sensitive skin under the Retin A.

Then gradually build up to using the medication every night, followed by increasing the dose of the Retin A.
