Purito SEOUL - Retinol Retinal 2000 NAD+ Serum 30ml

Begin by using it 2-3 times per week in the evening. As your skin builds tolerance, you can gradually increase frequency to nightly use if desired and well-tolerated.

It's best to avoid using other strong exfoliants (like AHAs/BHAs) or retinoids in the same routine when starting. Introduce other actives gradually and monitor your skin's reaction.

Retinal is a more direct precursor to retinoic acid (the active form of Vitamin A) than retinol, meaning it can potentially offer faster results. This serum contains both.

It is suitable for most skin types seeking anti-aging benefits. However, individuals with very sensitive skin should perform a patch test first and introduce it very gradually.

Retinoids can increase skin's sensitivity to the sun. Daily use of a broad-spectrum sunscreen (SPF 30 or higher) is crucial to protect your skin and prevent potential sun damage.

Visible results can vary per individual. Consistent use over several weeks to months is typically needed to observe significant improvements in skin texture, fine lines, and tone.

This can be a sign of over-application or introducing the product too quickly. Reduce usage to 2-3 times per week or apply a smaller amount. Ensure you are using a good moisturizer.

Apply a thinner layer of the serum. Ensure your skin is completely dry after cleansing before application. Wait a minute or two before applying moisturizer.

Retinoids can be sensitive to light and air over time. Ensure the bottle is stored correctly in a cool, dark place and the cap is sealed tightly. If significant changes occur, discontinue use.
