What are the common skin responses when adjusting to retinol? A. Retinol typically requires an initial adjustment period of up to 2 weeks. During this time, you may experience temporary reactions such as mild tingling, redness, or flaking. However, some people may not experience any noticeable reactions at all—this can vary depending on individual skin sensitivity. For external use only; patch test recommended prior to full use. Discontinue if irritation occurs. Q. I didn’t feel any reaction after the first use. Can I apply it to my entire face now? A. In some cases, retinol reactions may appear later rather than immediately. Even if you don’t feel any discomfort at first, we recommend that you do not increase the amount or frequency of use right away. Please follow the usage guide carefully during the first two weeks. Q. What should I do if my skin feels irritated? A. If you experience irritation while using the product, try reducing the frequency of use. You can also mix the serum with a soothing serum or a moisturizer to minimize discomfort. Q. Is it gentle enough for long-term use? A. Yes, as long as you’ve gone through the initial adjustment phase according to the instructions and your skin is responding well without discomfort, it is suitable for long-term use. Q. Should I only use this at night? A. Yes, we recommend using retinol products in your nighttime skincare routine because retinol is sensitive to light and heat. Even if you don't apply it during the day, retinol can remain active in your skin. So it's important to wear sunscreen daily during the period you’re using this product.
