Choose a serum with a retinol percentage suitable for your skin type.
It’s important to consider the concentration of retinol that’s appropriate for your skin. Start with a lower concentration (around 0.25% to 0.5%) to allow your skin to adjust. Once your skin has acclimated, you can gradually increase the concentration to higher levels (1% or more) if needed.
Retinol can cause common side effects such as dryness, tightness, flaking, and redness, especially when first introduced. These side effects typically subside within two to four weeks as your skin becomes accustomed to it. It’s important to persist through this adjustment period and continue using retinol.

Common side effects of retinol include dryness, tightness, flaking, and redness.
Apply retinol serum in the evening
Retinol serums are ideally used in the evening, before bedtime. Nighttime application provides optimal protection for your skin. After cleansing your face, apply a small amount of the serum and wait for about 20-30 minutes before following up with your moisturizer or other creams.
Moisturize
Use a hydrating moisturizer with healing and moisturizing properties after applying your retinol serum. Ingredients such as hyaluronic acid, glycerin, or ceramides will help maintain moisture levels, soothe the skin, and minimize dryness or flaking.
Use it consistently, but not too frequently
When introducing retinol serum into your skincare routine, start by applying it once or twice a week and gradually increase the frequency to allow your skin to adapt to retinol and reduce the risk of irritation. If your skin responds well, you can increase the frequency to three to four times a week. However, if you experience excessive redness or flaking, reduce the frequency.

Start by applying retinol serum once or twice a week and gradually increase the frequency.
While the goal with any skincare product is ideally daily use, you can still reap the benefits by using it a few times a week. How quickly you’ll see results will depend on the strength and type of retinoid.
Always wear sunscreen
Daily sunscreen with an SPF of 30 or higher is a must, even on cloudy days. This not only protects the gains you’ve made with retinol but also prevents premature skin aging.
Retinoids can be potent, but even those with sensitive skin can enjoy their benefits with a few adjustments. It’s best to start cautiously, applying the product once or twice a week. Mix it with your moisturizer to reduce the potential for irritation that retinoids may cause. Since everyone’s skin reacts differently to skincare products, it’s advisable to start with a lower concentration when trying retinol for the first time. Don’t overdo the frequency, either—once a week is enough to start, gradually increasing your skin’s tolerance. After a while, you can increase the frequency to twice a week or every other day.
Using a retinol serum can deliver excellent results in rejuvenating your skin, but it’s important to be mindful of potential unwanted side effects.
