Examples of tretinoin in a Sentence
Do not use products with tretinoin (or Retin-A) on the area.
Treatment for mild noninflammatory acne consists of reducing the formation of new comedones with medications including topical tretinoin, benzoyl peroxide, adapalene, or salicylic acid.
Tretinoin is especially effective because it increases turnover and replacement of skin cells.
One effective treatment is topical tretinoin, used along with a topical or oral antibiotic.
For example, lotions, soaps, gels, and creams containing substances called benzoyl peroxide or tretinoin may be used to clear up mild to moderately severe acne.
Benzoyl peroxide and tretinoin work by mildly irritating the skin.
Tretinoin (Retin-A) is available only with a physician's prescription.
Because antiacne drugs such as benzoyl peroxide and tretinoin irritate the skin slightly, users should avoid doing anything that might cause further irritation.
If benzoyl peroxide or tretinoin make the skin too red or too dry or cause too much peeling, the user should check with a physician.
Anyone who has had unusual reactions to etretinate, isotretinoin, tretinoin, vitamin A preparations, or benzoyl peroxide in the past should let the physician know before using an antiacne drug.
Teens who are pregnant or who may become pregnant should check with a physician before using tretinoin or benzoyl peroxide.
Tretinoin (Retin-A and Renova) are stronger forms of retinol.
Tretinoin, for example, commonly known as Retin-A, often results in worse acne, as well as photosensitivity, excessive redness and flaky skin.
In very severe cases, over-the-counter options may not be effective and prescription creams that contain tretinoin and cortisone cream could be required to see results.
Another topical treatment for rosacea is tretinoin.
Tretinoin belongs to a class of medications called retinoids, and works by speeding up the turnover of skin cells.
During the first few weeks of using tretinoin, rosacea may also appear even worse because the medication is working on pustules forming under the skin.
It typically takes up to 12 weeks to see results with the use of tretinoin.
Tretinoin Gel 0.05% is a retinoid treatment available by prescription only.
