It is recommended that you do not combine Retinal with exfoliating acids such as AHAs, BHAs, or PHAs, or with vitamin C, as this can put additional strain on the skin. Instead, it is recommended that you use them on different days.

The rule here is: slow and steady wins the race! Ideally, start by using it 1 to 2 times a week as part of your evening routine. If your skin tolerates it well, you can gradually increase the frequency. 

Retinal is often better suited for sensitive skin than traditional retinol. However, a gradual introduction is essential: Start with the lower concentration of 0.05% retinal (Absolute A) just 1 to 2 times a week. To further protect the skin barrier, we recommend combining it with soothing, moisturizing products. Applying Hydra Hero Milky Drops before the retinal serum serves as a hydrating base that soothes the skin. During the acclimation phase, you can also use the “sandwich method,” in which the retinal is layered between two layers of moisturizer to help improve tolerance.

It is recommended that you avoid using retinoids during pregnancy. If you are unsure, please consult your doctor before use.

While retinol requires two conversion steps in the skin to become its active form, retinal is just one step away. For this reason, retinal is often described as an effective and well-tolerated option among retinoids.
