How Does Tretinoin For Acne Work?

Tretinoin, also known as Retin-A, is one of the most effective acne treatments. However, it takes some time to see results.

The medication works by speeding up the epidermal turnover process, thereby shedding dead skin cells that buildup to create oily, dirty skin. It also reduces fine wrinkles and dark spots caused by sun damage.

How to Use

Before using tretinoin, wash your hands and cleanse the skin with a mild soap or cleanser. Avoid products that dry the skin, such as astringents or skin cleansers that contain alcohol. Also, do not use any other topical acne medication at the same time you are using tretinoin. This can cause irritation. Apply a small amount of the medication to cover a small area of the face, avoiding the eyes, lips and nose. A pea-sized amount is usually sufficient.

Your doctor may recommend applying tretinoin to your face every other night or even at longer intervals, depending on how your skin reacts. Be patient, as it can take weeks to see results from tretinoin. However, you should notice clearer and smoother skin after a few months of regular use. It’s also important to avoid sun exposure, as tretinoin makes the skin more sensitive to sunlight. Also, make sure to use a sunscreen with a high SPF value.


Before using tretinoin, always wash your face with a gentle cleanser & gently pat dry. Avoid excessively scrubbing your skin or using harsh soaps; this may cause or worsen your irritation.

Use tretinoin only as directed by your doctor. Apply a small amount of tretinoin to clean skin every night. A pea-sized amount is usually sufficient for most people. Use a moisturizer afterwards to reduce flaking that can occur. It can take 12 weeks or more to see results from tretinoin for acne. Don’t be discouraged if you don’t see immediate results; your doctor will titrate your dose & it will get better.

Avoid using other topical acne medications or skin products containing peeling agents (including benzoyl peroxide, salicylic acid, resorcinol) or astringents with alcohol, lime, or spices, unless your doctor approves them. These can irritate your skin & make it sensitive to sunlight. You should also use a sunscreen with SPF 30 or higher when going outside.

Side Effects

Tretinoin works to combat acne in several ways. First, it speeds up the epidermal turnover process by causing dead skin cells to shed faster than usual. This reduces the accumulation of dead skin cells that can block pores and create plugs known as blackheads and whiteheads.

It also prevents your sebaceous glands from producing excessive amounts of oil. Tretinoin is also an effective anti-inflammatory, which helps to reduce the inflammation that causes pimples.

During treatment, you may experience redness or swelling of the treated area. This is normal, but you should let your dermatologist know if the redness or swelling persists.

During treatment, you should avoid using facial scrubs, fragrant lotions or peels, alcohol-based cleansers and any other products that irritate the skin. This includes over-the-counter topical acne medications, such as salicylic acid and benzoyl peroxide, unless approved by your doctor. You should also stay out of the sun as much as possible, using sunscreen and covering exposed areas with clothing.


Tretinoin is one of the most effective prescription-strength treatments for acne. However, it takes time to work, and results may vary. It is important to keep in mind that the severity of your acne, your skin’s sensitivity, and your preferences will impact the results you experience. If you aren’t seeing the desired results, talk to your doctor about adjusting your treatment.

When tretinoin is applied to the skin, it accelerates the cell turnover process. This can cause the surface of the skin to flake and peel. However, this also helps to shed dead skin cells and unclog pores that can lead to the formation of acne lesions.

A small amount of tretinoin goes a long way, so it is best to use only a pea-sized amount. It’s also important to moisturize your skin, especially if it’s sensitive, and to avoid over-exfoliating while using this medication. Additionally, be sure to wear sunscreen during the day to minimize sun damage. Tretinoin for Acne
