CeraVe Hydrating Hyaluronic Acid Face Serum is a skincare product formulated to provide hydration to the skin, particularly with the use of hyaluronic acid. Here's a breakdown of the information provided in the product description:

1. CeraVe: This indicates that the product is part of the CeraVe brand, known for its dermatologist-developed skincare products that often include essential ceramides to support the skin barrier.

2. Hydrating Hyaluronic Acid Face Serum: This suggests that the serum is designed to deliver moisture to the skin, and it prominently features hyaluronic acid as a key ingredient. Hyaluronic acid is known for its ability to attract and retain water, helping to keep the skin hydrated and plump.

3. 1 fl oz: This refers to the volume or size of the product, indicating that it comes in a 1-fluid ounce container. Serums are typically applied sparingly, so a smaller size is common.

For the best results, it's generally recommended to apply a serum like this to clean, dry skin, before applying a moisturizer. Serums are often used to deliver concentrated active ingredients to the skin.

If you have specific skin concerns or conditions, consulting with a dermatologist is advisable before incorporating new skincare products into your routine.
