Hey Marian😊
Thank you for your question!✨
We recommend that you start using The Ordinary Glycolic Acid 7% Toning Solution about 1-2 times a week in the evening, especially if you are new to exfoliating acids. If your skin feels good, you can increase to 2-3 times a week. If you have sensitive skin, always patch test on a small area first.
Remember not to combine with other acids, retinol, or strong active ingredients the same evening, as it can be too much for the skin and disrupt the barrier.
Always finish with a moisturizing cream – and don’t forget sunscreen during the day.
Good luck with your skincare routine and hope you have a lovely day🌞
