Retinol is a form of vitamin A in the retinoid group. It is often use as an ingredient in anti-aging skin care products. Because retinol is outstanding in reducing wrinkles, reducing dark spots from acne, restoring dull skin, helping to exfoliate skin cells, increasing firmness and elasticity, making the skin look healthier and younger.

For those who use facial skincare products that contain retinol, you should be careful when using them because it is a substance that is very sensitive to light. For those who are prone to allergies or have dry skin. You should test for allergies on your forearm before using it for the first time every time. Because retinol will make your face drier than before and can easily become irritat.
If you are just starting to use it for the first time, you should not use it every day. You should use it 2-3 times and then gradually switch to using it every other day instead. If there is no swelling, redness, allergies, or itching, you can adjust to using it every day. However, if it is a facial skincare product that contains a high concentration of retinol, the ยูฟ่าเบท recommends that you only use it at night.

The process of retinol or retinoids in skin care is that retinoids will bind to retinoid receptors that are abundant in the epidermis. Then it will stimulate the expression of genes related to various skin processes, such as stimulating skin cell division, making the skin thicker, stimulating the synthesis of more collagen, especially collagen types 1, 3 and 7, inhibiting the enzyme that breaks down collagen and also helping to stimulate the synthesis of Glycoaminoglycan, resulting in more moisture in the skin.
In addition, retinoids have the ability to bind to abnormal or inflamed cells very well, such as areas with acne inflammation, which can reduce inflammation.
How to observe that you are definitely allergic to retinol and not just normal irritation. We recommends observing whether this is skin irritation or allergy by observing whether the skin is dry after application, slightly itchy like normal dry skin. But disappears after applying moisturizer, or if there is a burning sensation after application, the skin is swollen and red, then stop using it immediately.
