Which type of product should be strictly avoided for pregnant or nursing clients?

Pregnant or nursing clients should avoid certain products due to their potential risks to both the mother and the developing fetus or nursing infant.

Salicylic acid is a beta hydroxy acid commonly used to treat acne and exfoliate the skin. However, while it is often deemed safe in topical formulations in small concentrations, there is still some debate about its use during pregnancy, leading to recommendations for caution.

Vitamin A, particularly in its retinoid form, poses a significant risk during pregnancy. High doses of vitamin A can cause congenital disabilities in a developing fetus. Given its powerful effects on skin cell turnover and differentiation, it’s often advised to avoid products containing retinoids during this time.

Trichloroacetic acid (TCA) is a strong chemical peel agent used for more aggressive skin resurfacing. Such potent treatments can penetrate deeply and carry risks during pregnancy, including effects on the developing fetus.

Considering the potential hazards associated with all these products, the safest approach is to avoid them entirely for pregnant or nursing clients. This precaution protects both the mother and child from any uncertain side effects, which is why the choice to avoid all the listed products is the most prudent decision.
