Quick answer
MSM (methylsulfonylmethane) is a sulfur compound often touted for skin elasticity and firmness, while hyaluronic acid is a hydration powerhouse. They serve different purposes, and you may benefit from both depending on your skin goals. For plumping and moisture, choose hyaluronic acid; for a firmer look, consider MSM.
When scanning ingredient labels, you might wonder: what does MSM actually do for skin, and how does it stack up against hyaluronic acid? Both are popular in anti-aging serums, but they work in distinct ways. Let's break down the facts so you can decide which deserves a spot in your routine.
MSM is a form of sulfur, an element your body uses to build keratin and collagen. Hyaluronic acid, on the other hand, is a humectant that draws water into the skin. Understanding their unique actions helps you target specific concerns like dryness, sagging, or fine lines.
What is MSM and how does it benefit skin?
MSM, short for methylsulfonylmethane, is an organic sulfur compound. Sulfur is a key component of collagen and keratin, the proteins that keep skin firm and resilient. While direct research on topical MSM is limited, its role in supporting skin structure is why it appears in firming and anti-aging products.
In skincare, MSM is often combined with other active ingredients to enhance elasticity and reduce the look of sagging. For example, Odacité's Firming • Buriti + Lime • Bu+L Serum Concentrate uses rare Amazonian fruits and beta carotene to help skin look tighter and firmer, a similar goal to MSM-based formulas.

- Look for MSM in serums or creams aimed at firming and elasticity.
- Pair MSM with antioxidants like vitamin C for added anti-aging support.
Hyaluronic acid: the hydration hero
Hyaluronic acid is a naturally occurring molecule that can hold up to 1,000 times its weight in water. In skincare, it acts as a humectant, pulling moisture from the environment into the outer layers of your skin. This plumps fine lines and leaves skin looking dewy and fresh.
For example, Odacité's Clarifying Serum • Salicylic + Hyaluronic Acid combines this hydrating ingredient with salicylic acid to support a clear-looking complexion. The hyaluronic acid helps counterbalance any dryness from the exfoliating acid, making it suitable for blemish-prone skin that still needs moisture.

- Hyaluronic acid is ideal for dry or dehydrated skin types.
- It works well under moisturizers to lock in hydration.
MSM vs. hyaluronic acid: key differences
The main difference lies in their function: MSM supports skin structure (firmness, elasticity) while hyaluronic acid provides hydration (plumpness, moisture). They are not interchangeable; rather, they can complement each other in a well-rounded anti-aging routine.
If your primary concern is fine lines caused by dehydration, hyaluronic acid will give you the quick plumping effect. If you're worried about sagging or loss of firmness, MSM or other firming ingredients may be more relevant. Some products combine both, but it's not necessary to have both in every formula.
- For hydration: choose hyaluronic acid.
- For firmness: consider MSM or firming botanicals.
Myth-busting verdicts
- Myth: MSM is a hydrator like hyaluronic acid: MSM is not a humectant; it doesn't draw water into the skin. Its role is more about structural support. Use hyaluronic acid for hydration, not MSM.
- Myth: You need both MSM and hyaluronic acid in every product: Not necessarily. Depending on your skin concern, you might benefit from one more than the other. Combination products can be convenient but aren't mandatory. Choose based on your primary concern: dryness vs. firmness.
- Myth: All sulfur ingredients are the same: MSM is a specific form of sulfur. Other sulfur compounds may have different effects, such as treating acne. Don't assume all sulfur acts alike. Check the ingredient label for the exact form.
Products that put these ingredients to work

In the debate between MSM and hyaluronic acid, there's no clear winner—only what's right for your skin. For a hydration boost, opt for hyaluronic acid; for firming support, explore MSM or firming botanicals. You can even layer them in your routine, but always patch-test new products and adjust based on how your skin responds.
