While hyaluronic acid is a popular ingredient in skincare products and can provide hydration and plumping effects to the skin, it is important to note that it may not have a direct effect on reducing or treating stretch marks.

Stretch marks occur when the skin stretches rapidly, causing the collagen and elastin fibers in the dermis to break and tear. These marks are essentially scars that form as the skin heals. Hyaluronic acid primarily works by attracting and retaining moisture in the skin, improving hydration and elasticity.

To effectively address stretch marks, it is important to focus on ingredients that promote collagen production and skin regeneration. Some ingredients that have shown potential in reducing the appearance of stretch marks include:

1. Retinoids: Topical retinoids, such as retinol, can help stimulate collagen production and promote cell turnover, which may improve the appearance of stretch marks over time. However, it is important to use retinoids cautiously and follow proper usage guidelines, as they can cause skin irritation and sensitivity.

2. Vitamin C: This antioxidant can help promote collagen synthesis and improve the overall texture and appearance of the skin. Look for stable forms of vitamin C, such as ascorbic acid or ascorbyl palmitate, in skincare products.

3. Peptides: Certain peptides, such as palmitoyl tripeptide-5 or palmitoyl tetrapeptide-7, have been shown to stimulate collagen production and improve skin elasticity.

4. Moisturizers and oils: Keeping the skin well-hydrated can help improve its overall appearance. Look for moisturizers or oils containing ingredients like shea butter, cocoa butter, or rosehip oil, which can help improve skin elasticity and reduce the appearance of stretch marks.

While the Ordinary Hyaluronic Acid can provide hydration to the skin, it may not specifically target stretch marks. It is always a good idea to consult with a dermatologist or skincare professional for personalized advice and recommendations based on your specific needs.
