Is Hyaluronic Acid Good for Stretch Marks?

February 22, 2026

Hyaluronic acid can help reduce the appearance of early-stage stretch marks by deeply hydrating the skin and supporting collagen production. 

For those looking for a targeted treatment, products like Truly’s Diamond Baby Treatment Body Serum combine hyaluronic acid with peptides to increase skin hydration, improve texture, and help skin look smoother and firmer over time.

Can Hyaluronic Acid Reduce Stretch Marks?

Stretch marks (striae distensae) are a common skin concern that develop during periods of rapid growth, pregnancy, weight changes, puberty, or hormonal shifts. When the skin stretches quickly, collagen and elastin fibers can tear, leading to visible streaks that may appear red, pink, purple, or dark brown at first. Over time, they often fade to a lighter, scar-like tone.

While stretch marks aren’t harmful, they can affect how you feel about your skin’s appearance. Certain skincare ingredients like hyaluronic acid may be able to help reduce the depth and intensity of stretch marks. 

Hyaluronic acid is a powerful humectant, meaning it attracts and retains water in the skin. In fact, it can hold up to 1,000 times its weight in water. This intense hydration combined with its ability to boost collagen and elastin in the skin can help improve the look of stretch marks on the chest, stomach, thighs, or wherever they may appear.

What Does Hyaluronic Acid Do for Stretch Marks?

1. Plumps & Hydrates

By drawing moisture into the skin, hyaluronic acid helps make the skin appear plumper and smoother. This plumping effect can temporarily reduce the depth and visibility of early stretch marks.

2. Improves Skin Elasticity

Well-hydrated skin is more elastic than dry skin. Because stretch marks form when skin is stretched beyond its capacity, improving elasticity can help support the skin’s overall appearance and prevent stretch marks from appearing more pronounced.

3. Stimulates Collagen Production

Hyaluronic acid helps create an optimal environment for collagen synthesis. Collagen is essential for firm, strong skin. Increasing collagen support can gradually improve skin texture and make stretch marks appear less noticeable over time.

According to the American Academy of Dermatology, two large studies found that applying hyaluronic acid to early stretch marks made them less noticeable. This suggests HA may be most effective during the early (red or purple) stage rather than on older, white stretch marks.

How to Use Hyaluronic Acid for Stretch Marks

To get the best results, we recommend applying a high quality hyaluronic acid serum to the affected areas on a daily basis for at least 4 weeks. Our top pick is Truly's Diamond Baby Treatment which combines hyaluronic acid with diamond peptides to deeply penetrate the skin's layers to visibly plump and increase skin hydration for a smoother, firmer appearance.

Clinical results show that this serum helped lift, firm, improve the look of crepey skin, and restore elasticity within 56 days of consistent use. 

To enhance the benefits of this serum, spend a few minutes massaging into your skin, as research suggests daily massage can help improve scar quality. 

Hyaluronic Acid for Early vs. Old Stretch Marks

Timing matters when it comes to seeing visible results from hyaluronic acid on stretch marks.

Early Stretch Marks (Red, Pink, or Purple)

These marks are still in the inflammatory phase. Because the skin is actively remodeling, topical treatments like hyaluronic acid tend to be more effective at this stage.

This aligns with findings referenced by the American Academy of Dermatology, which show improvement when hyaluronic acid is applied early.

Older Stretch Marks (White or Silver)

Older stretch marks are more scar-like and less responsive to topical ingredients alone. While hyaluronic acid can still improve hydration and surface texture, deeper remodeling treatments such as microneedling, laser therapy, or prescription retinoids may provide more dramatic results.

Does Hyaluronic Acid Remove Stretch Marks Completely?

No topical product, including hyaluronic acid, can completely erase stretch marks. Once the dermis has been damaged, stretch marks are technically a form of scarring.

However, hyaluronic acid can:

• Improve skin hydration
• Smooth uneven texture
• Support collagen health
• Reduce the appearance of early stretch marks

For deeper or older stretch marks, dermatological treatments like microneedling, laser therapy, or retinoids may provide more dramatic results. We suggest consulting with a dermatologist for the best course of action when you have older, deeper stretch marks.

Should You Use Hyaluronic Acid for Stretch Marks?

Hyaluronic acid is a safe, effective ingredient for reducing the appearance of stretch marks, especially early-stage ones. By deeply hydrating the skin, supporting collagen and elastin, and improving elasticity, it helps smooth, plump, and refine skin texture.

While it won’t completely erase stretch marks, consistent use of hyaluronic acid products such as Truly’s Diamond Baby Treatment Body Serum can visibly help skin look smoother, firmer, and tighter over time.
