When incorporating tretinoin into your skincare routine, it is important to start slow and gradually increase frequency to avoid irritation. Generally, you should start by applying tretinoin once every two to three nights, gradually increasing frequency to every other night and eventually nightly as your skin tolerates it.

After washing your face, wait at least 20 to 30 minutes before applying tretinoin to allow your skin to fully dry. This will help reduce irritation and ensure proper absorption of the product.

You can then apply hyaluronic acid after the tretinoin has fully absorbed, typically after 15 to 20 minutes. This will help to hydrate and soothe the skin.

Remember to always wear sunscreen during the day, as tretinoin can make the skin more sensitive to UV rays. Start with a low concentration and gradually increase as your skin tolerates it. Also, avoid using other harsh exfoliants or actives in your routine, as this can increase the risk of irritation.

Some additional tips for using tretinoin include avoiding the eye area, as this skin is more sensitive and prone to irritation, and using a moisturizer to help soothe and hydrate the skin.
