What effect does retinoic acid have on the skin?

1. Hydration

2. Peeling

3. Firming

4. Darkening

The correct answer is: Peeling

Retinoic acid, a derivative of vitamin A, is known for its significant impact on the skin, particularly in relation to cell turnover and exfoliation. When applied, retinoic acid accelerates the shedding of dead skin cells from the surface, promoting a process known as peeling. This action not only helps to improve the overall texture of the skin but also facilitates the reduction of acne, minimizes fine lines, and promotes an even skin tone. Regarding the other choices, options like hydration and firming do not primarily relate to the action of retinoic acid. While retinoic acid can lead to improved skin texture and might contribute to the appearance of firmness over time, its immediate and most recognized effect is the promotion of cell turnover through peeling. Darkening, on the other hand, would not be a representative effect of retinoic acid; instead, it could potentially lead to increased sensitivity or irritation in some cases, particularly if used improperly, but deriving a darkening effect wouldn’t be accurate. Thus, peeling accurately characterizes one of the hallmark effects of retinoic acid.
