Applying a barrier cream is the most effective method to prevent skin irritation during treatments. Barrier creams create a protective layer on the skin, which can help shield it from potential irritants or allergens present in the products used during treatments. This layer acts as a buffer, reducing direct contact between the skin and any substances that could cause irritation.

In contrast, using more product may actually increase the likelihood of irritation, as it can overwhelm the skin with too many active ingredients or chemicals. Increasing the treatment time also poses a risk, as prolonged exposure to certain products can lead to irritation, especially if the skin is sensitive. Lastly, using a lower quality product is not advisable; these products may contain harsher ingredients or irritants that can exacerbate skin irritation rather than alleviate it. Hence, applying a barrier cream stands out as the most prudent choice for maintaining skin health during cosmetic treatments.
