Mediocre retinol. Not bad but not great either. Does not cause irritation (provided the skin barrier is restored and used correctly). There is a smell, not annoying, but it is better without fragrances in such products

Over all it’s good product, no irritation and nice texture

Хорошая сыворотка,мне понравился продукт,удобная помпа и лёгкая сыворотка

The claims that this is the most gentle retinol to get started have intrigued me I’ll be updating this soon

Love dr althea brand. I never have any issues with their products
