5. How to use retinol in your skin care routine
You can start retinol by using it at night, several times a week. Here's how to start incorporating retinol into your daily skincare routine:
Wash your face and wait until it's completely dry. Some products may work better when applied to damp skin, but with retinol, moist skin can increase irritation. Take a pea-sized amount of retinol product. Start applying from the chin in an upward and outward direction. Apply evenly to the face, but be careful to avoid the eye and mouth area Next, you can apply skin care products such as serum or cream. Because retinol can cause dryness, it's a good idea to use an effective moisturizer to help keep skin moisturized and protect the skin's barrier. Finally, don't forget to apply sunscreen if you use retinol during the day. Consult a dermatologist before using a retinol if you are using any other topical acne treatments. In general, retinol is incompatible with vitamin C or hydroxy acids, as those ingredients can also cause skin irritation. On the other hand, retinol products are great for pairing with moisturizers or products that include hyaluronic acid or niacinamide.
