The method of combining azelaic acid with retinoic acid
Azelaic acid and retinoic acid are both good skin care medicines. However, if the two are synergistic, the method of using them is very particular.

First talk about cleansing. If you want to use these two, you must first use a gentle cleansing product to cleanse your face, remove oil and dirt, make your skin refreshing, and pave the way for subsequent skin care. After rinsing with water, wipe it lightly with a soft towel, do not rub it vigorously, and avoid hurting your skin.

As for the order of use, there are quite a few ways. Generally speaking, you can apply azelaic acid first. Take an appropriate amount of azelaic acid cream or gel, gently tap it on your face, and push it evenly to avoid sensitive areas such as the eyes and corners of your mouth. Azelaic acid can improve uneven skin tone, fight acne, and help smooth the skin. Wait for it to dry a little and form a film, about a few minutes later, then use retinoic acid. Retinoic acid can promote keratin renewal, improve skin metabolism, and has a good effect on acne, fine lines, etc. However, because it has a certain irritation, it needs to be used with caution at first. Take a small amount of retinoic acid and apply it thinly to the surface, from less to more, to gradually build skin tolerance.

The frequency of use should also be paid attention to. In the initial stage, both can be used every other day to observe the skin's reaction. If the skin is well tolerated, there is no redness, swelling, tingling and other discomfort, it can be gradually increased to once a day. However, retinoic acid has strong photosensitivity and is suitable for use at night. Be sure to do a good job of sun protection during the day. Protect it with parasols, sunglasses, sunscreen, etc., to prevent sunburn and sun aging.

During the combination of the two, the skin may appear dry and peeling, which is a normal reaction. Moisturizing steps can be added in a timely manner, such as using moisturizing creams and masks to hydrate and lock the skin and relieve discomfort. If the discomfort is serious, you should suspend use and consult a professional. In this way, the combination of azelaic acid and retinoic acid according to this method can make the skin glow and achieve the ideal skin care effect.
