What is Retin A Cream?

Retin A, also known as Tretinoin, is a medication belonging to the class of retinoids and is commonly used to treat acne. It comes in different forms and dosages, such as cream or gel, and is considered a retinoid because it derives from vitamin A. Retinoids are compounds that have similar effects to vitamin A in the body, with the ability to regulate cell growth and differentiation, improve collagen production, and reduce sebum production. To buy Retin A online from Canada, a prescription from a healthcare professional is necessary.

Dosage and Uses

This discussion will focus on the uses, storage, and differences between Retin A and Tretinoin. The dosage of Retin A, which is a retinoid medication, varies depending on the form (cream or gel) and strength (0.025%, 0.05%, or 0.1%). 

Dosage of Retin A

The dosage of Retin A should be applied once a day and closely monitored to determine the patient’s therapeutic response and skin tolerance, as individualized needs may vary. It is important to note that the gel, cream, and liquid forms contain tretinoin in different strengths. Four key points regarding the dosage of Retin A are as follows:

  1. Regular monitoring: Regular monitoring is essential to evaluate the effectiveness of the medication and any adjustments that may be required.
  2. Time for results: The time it takes for therapeutic results to become visible can vary from individual to individual. While some may experience improvement within two to three weeks, others may need more than six weeks.
  3. Individualized treatment: As each patient’s skin tolerance and response can differ, healthcare providers may need to adjust the dosage and formulation accordingly.
  4. Adjustments in frequency: Once the acne lesions have responded satisfactorily, applications can be reduced or other dosage forms of Retin A may be considered.

By closely monitoring the dosage and considering individual factors, healthcare providers are able to optimize treatment outcomes for acne vulgaris patients.

Conditions Treated by Retin A Cream

Retin A contains vitamin A and works to renew the skin by decreasing fine wrinkles, reducing mottled skin discoloration, and smoothening rough facial skin. While the primary purpose is for treating acne, it can also be effective in improving other skin issues. However, it is essential to note that Retin A should only be used with a healthcare professional’s prescription.

To give a better comprehension of the uses of Retin A, here is a table outlining its main indications:

Skin Condition



Decreases the number and severity of acne pimples and promotes fast healing

Fine Wrinkles

Reduces the visibility of fine lines and wrinkles on the face

Mottled Skin Discoloration

Enhances uneven pigmentation or dark spots on the skin

Rough Facial Skin

Makes rough facial skin smoother

It is worth noting that while Retin A can offer positive results, it may take several weeks or months to observe notable improvements. In addition, precautions should be taken when using this medication, such as avoiding sun exposure and following correct application techniques. 

How to store

Storing this medication correctly is essential to maintain its effectiveness and extend its shelf life. Refrigeration may not be essential for tretinoin cream, but it can slow down the degradation of the active ingredient. Conversely, it is recommended to store retinol and vitamin C serums in the fridge to prevent them from spoiling. Cool temperatures can also extend the life of skincare products that contain retinol or vitamin C. However, most skincare products are designed to be stored at room temperature without complications. 

Retin A vs Tretinoin

Retin-A and tretinoin are the same medication, with Retin-A being the brand name and tretinoin being the active ingredient. Generics are often prescribed to save money, as they have the same effects. It is a type of retinoid used to treat acne and also has anti-aging properties. Other medications containing tretinoin include Retin-A Micro, Avita, Renova, and Ziana. Retin-A Micro delivers tretinoin more slowly for less irritation compared to Retin-A, while over-the-counter retinol is derived from vitamin A and works at a slower rate.

Recent evidence-based guidelines for acne, including those from the American Academy of Dermatology (AAD) and the European Dermatology Forum (EDF), have agreed that retinoids have an essential role in this widespread disease.

Consulting healthcare professionals or pharmacists is crucial for understanding the differences between these medications and asking any related questions. Both brand-name and generic tretinoin have similar benefits, such as keeping pores clear, softening fine lines, and fading discolorations.

Side Effects and Warnings

When using Retin A, it is important to be aware of the potential side effects and warnings associated with the medication. While it can effectively decrease the number and severity of acne pimples and promote quick healing, there are some precautions that should be taken.

Side effects of Retin A may include:

  • Dryness
  • Itching
  • mild burning
  • skin redness
  • blistering
  • crusting
  • eye redness and watering
  • eyelid swelling
  • skin discoloration

These symptoms are usually mild and temporary, but if they become severe or persistent, medical attention should be sought.

Warnings and Precautions of Retin A Usage

There are certain warnings and contraindications that should be considered before starting Retin A therapy.

One of the main contraindications is hypersensitivity to tretinoin or any of its components. Patients with evidence of hypersensitivity should not use this medication. Additionally, this should not be used during pregnancy due to the high risk of fetal loss and malformations. Effective contraception must be used throughout treatment and for one month after discontinuation, even in patients with a history of infertility or menopause.

Patients without genetic markers t(15;17) translocation may need alternative treatment options as well. Oral tretinoin is contraindicated during breastfeeding, caution is advised during pregnancy (especially in the first trimester), and caution is advised in females of reproductive potential and pediatric patients.

For topical usage, caution should be exercised if there is hypersensitivity to fish products, sunburn, photosensitivity, eczema, or pregnancy in the first trimester, as these conditions may increase the risk of adverse reactions.

It is essential to consult with a healthcare professional before starting Retin A therapy and follow their guidance closely regarding these warnings and contraindications. This will help ensure safe and effective usage while minimizing potential risks associated with this medication.

Drug Interactions of Retin A

Interactions between Retin A and other medications should be taken into consideration to ensure safe and effective usage. Healthcare professionals should carefully review a patient’s medication profile before prescribing Retin A to avoid any potential complications.

Particular caution should be exercised when using Retin A in combination with other drying products or high alcohol concentrations, as this could lead to increased skin irritation or dryness. Additionally, this belongs to a class of medications called retinoids, which can have various effects on the body. Therefore, it is important to identify any possible interactions with other drugs that may affect their efficacy or increase the risk of side effects.

Sun exposure should also be minimized while using Retin A due to its potential photosensitizing effects. Combining Retin A with other medications that increase sun sensitivity could further increase the risk of sunburn and adverse effects from sunlight exposure.

Here is a list of medications that interact with Retin A:

  • methyl aminolevulinate topical
  • aminolevulinic acid
  • aminolevulinic acid topical
  • sulfur topical
  • clascoterone topical
  • isotretinoin
  • verteporfin
  • methoxsalen
  • benzoyl peroxide topical
  • porfimer
