It is recommended that you do not use Retinal in combination with exfoliating acids such as AHA, BHA, or PHA, 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 incorporating it into your evening routine 1 to 2 times a week. If your skin tolerates it well, you can slowly increase the frequency. 

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

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 requires only a single step. For this reason, retinal is often described as an effective and well-tolerated option among retinoids.
