Tretinoin Cream- Advantages, Usage, & Side Effects


What Is Tretinoin?

Tretinoin, also known as all-trans retinoic acid, is a medication used for the treatment of acne, photoaging, and other skin conditions. It is a derivative of vitamin A and belongs to the retinoid family of medications. Tretinoin works by affecting the growth and differentiation of skin cells, reducing the production of sebum, and promoting the turnover of skin cells, which can help improve the appearance of the skin. It is available in various forms, including creams, gels, and solutions, and is typically applied topically to the affected areas of the skin. 


Tretinoin has several advantages when used as directed by a medical professional or dermatologist:

1. Effective in treating acne: Tretinoin is a highly effective treatment for acne, particularly comedonal acne (blackheads and whiteheads), and has been shown to reduce the number and severity of acne lesions.

2.  Reduces fine lines and wrinkles: Tretinoin is a proven anti-ageing treatment that can help reduce the appearance of fine lines, wrinkles, and other signs of ageing on the skin. It works by stimulating collagen production, which helps to keep the skin firm and elastic.

3. Improves skin texture and tone: Tretinoin can improve the overall texture and tone of the skin, making it smoother, softer, and more even in colour.

4. Can be used for other skin conditions: Tretinoin is effective in treating other skin conditions, such as psoriasis, and may also be used to reduce the appearance of scars.


Tretinoin is primarily used as a topical medication to treat acne and reduce the appearance of fine lines, wrinkles, and other signs of ageing on the skin. It works by speeding up the turnover of skin cells, which helps to unclog pores and prevent the formation of new acne lesions. It also stimulates collagen production, which helps to keep the skin firm and elastic, improving the appearance of fine lines and wrinkles. In addition to acne and anti-ageing, tretinoin has also been shown to be effective in treating other skin conditions such as

Psoriasis: Tretinoin has been shown to improve the symptoms of psoriasis, a chronic skin condition that causes patches of red, scaly skin.

Hyperpigmentation: Tretinoin can help to reduce the appearance of hyperpigmentation, such as age spots and melasma, by promoting skin cell turnover and exfoliation.

Keratosis pilaris: Tretinoin can help to reduce the appearance of small, rough bumps on the skin that are caused by a buildup of keratin, a protein that protects the skin.

What Percentage Tretinoin Is Available?

the most common concentrations of tretinoin available in the market are- 

0.01% tretinoin cream/gel: This is the lowest concentration available, and is usually recommended for people with sensitive skin or those who are new to tretinoin therapy.

0.025% tretinoin cream/gel: This is a moderate-strength concentration that is often used to treat mild to moderate acne, fine wrinkles, and hyperpigmentation.

0.05% tretinoin cream/gel: This is a higher strength concentration that is typically used to treat moderate to severe acne, as well as more pronounced signs of ageing such as deeper wrinkles and more noticeable hyperpigmentation.

0.1% tretinoin cream/gel: This is the highest strength concentration available, and is generally reserved for severe acne or very deep wrinkles and hyperpigmentation. This concentration is usually recommended for those who have already been using tretinoin for some time and have built up a tolerance to lower concentrations.

What Percentage Should I Start With?

The percentage of tretinoin cream that you should start with will depend on your skin type and the severity of your condition. Generally, it’s always best & recommended to start with the lowest concentration to avoid side effects and gradually increase over time.

How To Use Tretinoin Cream?

  1. Cleanse your face and wait for your skin to dry completely before applying the cream.
  2. Apply a pea-sized amount of tretinoin cream to your fingertips.
  3. Gently massage the cream into your skin, being careful to avoid the eye area.
  4. Start with a low concentration of tretinoin cream, such as 0.025%, and use it every other night for the first week or two. This will help your skin to adjust to the medication and reduce the likelihood of irritation.
  5. After a few weeks, you can increase the frequency of use to every night, if your skin tolerates it.
  6. Avoid using tretinoin cream with other topical medications that can cause irritation, such as benzoyl peroxide.
  7. It’s important to use sunscreen during the day when using tretinoin cream, as it can make your skin more sensitive to the sun.
  8. If you experience severe irritation, redness, or peeling, stop using the medication and consult with a certified dermatologist.

Side Effects

Like any medication, tretinoin can cause side effects, although not everyone who uses it will experience them. Some common side effects of tretinoin are-

Skin irritation: Tretinoin can cause redness, itching, burning, and peeling of the skin, particularly during the first few weeks of use. This is usually temporary and improves as the skin gets used to the medication.

Dryness: Tretinoin can cause dryness of the skin, which may be accompanied by flaking or scaling. This can be managed with the use of a moisturizer.

Sensitivity to sunlight: Tretinoin can increase the skin’s sensitivity to sunlight, making it more prone to sunburn. It is recommended to avoid excessive sun exposure and to use sunscreen with a high SPF when going outdoors.

Increased risk of skin infections: Tretinoin can increase the risk of skin infections, particularly if the skin is already damaged or broken.

Hyperpigmentation: In rare cases, tretinoin can cause hyperpigmentation, or darkening of the skin. This is usually temporary and fades once the medication is discontinued.

Teratogenicity: Tretinoin has been associated with an increased risk of birth defects when used during pregnancy, and therefore it is not recommended for use during pregnancy or breastfeeding.

  • People who have an allergy to tretinoin or other retinoids.
  • People who have eczema or other skin conditions that cause chronic skin irritation or sensitivity.
