Retinol is a popular skincare ingredient known for its ability to improve skin texture, reduce wrinkles, and minimize pores. It has lately become extremely popular, and many over-the-counter products are promising the impossible: making our face look younger and assisting in fighting acne. 

Retinol is a form of vitamin A. It is applied topically to the skin and is available in various forms, such as moisturizers, gels, ointments, and serums. It is often a key ingredient in many cosmetic products, improving the texture and appearance of the skin. Retinol increases cell renewal, which helps to keep pores clean and reduce the appearance of imperfections. It also acts as an exfoliator for the skin and boosts collagen production, supporting the reduction of fine lines and wrinkles, leading to skin that looks more youthful and firm. Studies show that topical retinoids help with acne scars and stretch marks. 

While effective, retinol products can be irritating, especially when first used. Choosing the right product and applying it carefully is important to avoid irritation. You can find several over-the-counter products with retinol, but for more potent concentrations, it's best to consult a dermatologist since they can recommend the right products that incorporate higher-concentration retinoids and are suitable for your skincare routine.

Before using a product containing retinol for the first time, it is important to test a small skin area. This will help you to see if you have any adverse reactions, such as irritation or allergy. If, after a few days, your skin does not show severe redness or itching, you can incorporate retinol into your evening skincare routine. You should always follow the instructions on the packaging or your dermatologist’s advice in order to minimize any skin reaction to retinol and benefit the most. Retinol is generally applied as part of your evening routine, and it’s important not to forget the moisturizer after using it. The following steps are generally recommended:

• Wash your face with a mild cleanser and gently pat dry. Avoid rubbing the skin, as retinol can make it more sensitive.

• Use a small amount of retinol, about the size of a pea, and apply it all over the face, avoiding the eyes, nose, and mouth. For the first two weeks, apply the product every other day.

• Complete your routine with a non-fasting moisturizer to avoid clogging pores.

Side Effects

While retinol is FDA-approved, it’s not free from side effects. The most common side effects of retinol use are usually temporary and may include:

• Dryness and irritation of the skin

• Itching or burning sensation

• Redness, peeling, or scaling of the skin

• Increased sensitivity to the sun

These reactions usually subside as the skin adjusts to the use of the product.

What is also important to remember is that retinol use can increase the skin's sensitivity to the sun, making it more susceptible to sunburn. In some cases, high-dose use may be associated with an increased risk of developing skin cancer. To avoid these risks, it is important to use sunscreen and avoid direct exposure to the sun by protecting your skin with clothing and hats and always apply retinol as a part of your evening routine —not in the morning.
