Why do I have to apply the Vita-A-Kombi 3 with the brush? Vita-A-Kombi 3 contains 3% active oxygen. As soon as the cream touches the skin the oxygen reaction is triggered by the catalase enzyme in the skin. To avoid the absorption of the oxygen by the fingertips, we recommend applying all oxygen products with a brush. So the effects of the oxygen are left for the areas where you really need them.
Can I use the Vita-A-Kombi 3 with sensitive skin or skin conditions? Yes you can! The regenerating properties of active oxygen are in particular great to locally treat skin conditions and sensitive skin since they boost cell regeneration and healing. Additionally, vitamin A is applied to the skin in its neutral form and only acidified under the skin to unfold its anti-aging effects without irritation. We do recommend though to use this treatment really restrictively and locally with sensitive skin and use a lower concentration of active oxygen for the rest of the face.
