Yes it has been and the recommended alternative from the Neostrata range is: 

NEOSTRATA "Skin Active" Potent Retinol Complex 30ml

which is available end of September 2024 and contains: 0.3% Pure Retinol, 4% Niacinamide and 2% NeoGlucosamine, while boosting nourishment and hydration with Centella Asiatica and Hyaluronic Acid.

If you are concerned that this option might be too potent, we would suggest Junoskin Retinol Revitalise that has supportive ingredients and peptides to make the retinol better tolerated by sensitive skins.
