Paula's Choice Clinical Pro Retinaldehyde Dual-Retinoid Treatment is a must-have for anyone concerned with acne and signs of ageing, such as wrinkles, fine lines, and loss of firmness. Unlike traditional retinoids, this advanced formula features 0.1% retinaldehyde, the closest over-the-counter ingredient to prescription retinoic acid, delivering powerful results with little to no irritation. Clinical Pro Retinaldehyde Dual-Retinoid Treatment is a first-of-its-kind dual retinoid that is directly broken down to retinoic acid, meaning it can be absorbed faster and easier into the skin cells compared to retinol. The dual approach, combining retinaldehyde and 0.16% Adapinoid®, tackles uneven skin texture, enlarged pores, and blemishes while promoting clearer, more radiant skin. This treatment delivers clearer, smoother skin in just two weeks, with dramatic results in just eight weeks.
