**This product contains retinal, a more potent form of retinol that converts to retinoic acid in the skin. Retinal provides similar benefits to retinol but often with more noticeable effects and faster results. It is generally less irritating than retinoic acid, which is available only by prescription.

Application Frequency: In the early stages of treatment, as your skin builds tolerance, retinoids may cause significant irritation, such as redness, dryness, and peeling, especially around the eyes, nose, and mouth. Start by using the product 2-3 times a week, gradually increasing the frequency as your skin adapts.

Avoid Combining with Certain Products: Be cautious when layering retinoids with other active ingredients like benzoyl peroxide, AHAs/BHAs, or vitamin C, as these can increase irritation. If using these ingredients, it’s recommended to apply them at different times of the day.

Product Storage: Store the product in a cool, dark place, preferably in the refrigerator, both before and after opening.

Sun Sensitivity: It is recommended to use retinoid products only in the evening and always apply a broad-spectrum sunscreen with at least SPF 30 the following morning. Retinoids can increase sun sensitivity, leading to a higher risk of sunburn.

Pregnancy and Breastfeeding: It is strongly advised to avoid retinoid products during pregnancy or while breastfeeding. Always consult a healthcare provider before use.
