How do I use tretinoin on my skin?

Tretinoin is a topical retinoid that people often use to treat acne, reduce wrinkles, and improve skin texture. 

It comes in cream, gel, and solution forms. Doctors usually prescribe it under different brand names, such as:

• Atralin
• Retin-A
• Renova
• Avita
• Refissa

In the United States, tretinoin typically requires a prescription. But some lower-strength retinoids, like adapalene (Differin), are available over the counter.

How do I use tretinoin for best results?

To use tretinoin for best results, follow these steps:

• Start with a lower concentration: If you’re new to tretinoin or have sensitive skin, start with a lower concentration to minimize irritation.
• Cleanse your skin: Before applying tretinoin, wash your face with a mild soap and pat it dry. If applying tretinoin to damp skin, wait about 20 to 30 minutes until your skin is completely dry to minimize irritation.
• Apply a small amount: Use a small amount, about the size of a pea, and apply a thin layer evenly across your entire face. Avoid sensitive areas like the eyes, corners of the mouth, and nostrils to reduce irritation.
• Adjust frequency slowly: Start by applying tretinoin every other night. As your skin builds tolerance, you can slowly increase to nightly use. If irritation occurs, reduce how often you use the drug (frequency) to give your skin time to adjust.
• Use at night and apply sunscreen during the day: Apply tretinoin at night since it makes your skin more sensitive to sunlight. In the morning, always use a broad-spectrum sunscreen to protect against sun damage.
• Choose the right form for your skin type: Creams are usually more hydrating, making them a good choice for dry or sensitive skin, while gels are less oily and work well for oily or acne-prone skin.
• Match the concentration to your treatment goals:
  • Acne: For mild acne, dermatologists often recommend starting with a lower concentration of tretinoin. Whereas severe cases may require a higher strength, like 0.05%.
  • Aging support: The most common strength of tretinoin used for aging support is 0.05%, though the best strength for you may vary depending on your skin type and tolerance.
  • Skin texture: Consistent use of a lower to moderate concentration can gradually improve skin tone and reduce the appearance of scars.

Tretinoin works gradually, with most people seeing improvement in their symptoms in about 12 weeks. It may take several months of consistent use to see the full benefits of tretinoin.

How should I use tretinoin with moisturizer?

Using tretinoin with a moisturizer can help reduce common side effects like irritation and dryness. You can apply moisturizer before or after tretinoin. 

Here’s how to do it effectively:

• Moisturizer before tretinoin: Applying a moisturizer before tretinoin helps create a barrier that reduces irritation. This technique, also known as the “tretinoin sandwich” method, is helpful for people new to using tretinoin or people with sensitive skin.
• Moisturizer after tretinoin: Applying a moisturizer after tretinoin can help seal the treatment and maintain hydration. This step is important, especially if you have dry or combination skin.

Choose a fragrance-free moisturizer that won’t clog pores to help avoid irritation. Look for hydrating ingredients like ceramides, hyaluronic acid, and glycerin to keep your skin moisturized.

Some products can increase irritation when combined with tretinoin. So a healthcare professional may recommend avoiding:

• harsh soaps
• skin products with alcohol
• shampoos
• hair removal creams
• astringents (liquid-based formulas that may help cleanse skin and pull out oils)
• citrus-based ingredients like lime

However, sometimes tretinoin may be combined with other active ingredients to enhance its effects and reduce irritation. 

These mixtures often include antibiotics, benzoyl peroxide, and niacinamide, which help treat various skin concerns.

Common combinations include:

• tretinoin with clindamycin (Veltin, Ziana)
• tretinoin with benzoyl peroxide (Twyneo)
• tretinoin with niacinamide

Tretinoin dosage

Tretinoin comes in different concentrations, and the right dosage depends on your skin’s needs and tolerance. 

• Acne: Different tretinoin strengths can help manage acne. But some studies show that higher concentrations, like 0.1%, can be more effective than lower ones.
• Aging support: For aging support, research shows that higher concentrations, such as 0.05%, can be effective, though the dose may vary.

The Food and Drug Administration (FDA) recommends using tretinoin every other night at first, slowly increasing to nightly use as your skin adjusts.

It also warns against stopping tretinoin without guidance from a healthcare professional, as this may cause your skin to return to its previous state over time.

To find the right tretinoin dosage for your skin, talk with a healthcare professional. They can help you choose the best option.
