Answer :
Final answer:
A preservative facial aims to maintain overall skin health and does not treat specific issues, while a corrective facial targets specific skin conditions such as acne or dryness, often using active ingredients or specialized treatments. The correct options are a,b,c and d.
Explanation:
A preservative facial and a corrective facial have different purposes in skincare. The former is aimed at preserving the existing condition of the skin, maintaining overall facial health, and potentially including substances that prevent spoilage and contamination. Preservative facials typically do not address specific skin conditions but instead focus on the overall maintenance of a healthy complexion.
In contrast, a corrective facial is specifically tailored to treat particular skin issues such as acne, dryness, or oiliness. Corrective facials often utilize products containing active ingredients to address these concerns, such as salicylic acid, retinoids, and benzoyl peroxide among others. For instance, treating acne can vary depending on severity, and a corrective facial for severe acne might involve the application of medication like isotretinoin or techniques like phototherapy and laser therapy.
