As long as you have the serum sandwiched between slightly damp skin and a moisturizer, you're good to go. It really plumps up the skin and makes it look nice and moisturized, and stays moisturized, throughout the day. NT: You definitely want your skin to be wet or damp before applying a hyaluronic acid serum.
You just need to make sure you're applying it correctly. As a rule, you want to apply your hyaluronic acid product to clean, damp skin, and the lock it in with a moisturizer and face oil. “If you put hyaluronic acid on top of a sunscreen or a moisturizer, it's not going to work,” Dr. Talakoub says.
Well, the quick answer is yes, you can mix serums with moisturisers. For this, you should follow the same guidelines as when you mix two serums together. Mix a couple of drops of serum in the palm of your hand with the moisturiser of your choice. Then just apply it to your face.
“Hyaluronic acid plays well with most ingredients, while caution must be taken when using retinol in combination with alpha hydroxy and beta hydroxy acids, benzoyl peroxide, and some types of vitamin C.”
Goldenberg's go-to recommendation for timing between serums and moisturizers is about one minute. This wait has the same reasoning: Sixty seconds — give or take — gives each product a moment to delve into your pores.

"It's important to apply HA before your other serums because it helps to seal in the moisturizer you'll be putting on top," confirms board-certified dermatologist Shari Sperling, DO. She adds that it works great as a moisturizer because of how well it binds to water, plumping and hydrating your face.
Can You Use Hyaluronic Acid and Vitamin C Together? Not all powerful skincare ingredients can be mixed, but hyaluronic acid and vitamin C are two that become even stronger when paired with one another. These ingredients can provide both immediate and lasting results when used together in anti-aging formulations.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out skin and cause further irritation if your skincare routine already includes retinol.
These “can cause an increase in skin cell turnover which can lead to purging—a breakout of spots in areas where you would normally get acne. However, hyaluronic acid does not increase skin cell turnover; it's purely a hydrating skincare ingredient.” In short, hyaluronic acid isn't to blame for any breakouts.
To allow serums to fully absorb, apply and wait 5 minutes before moisturizing. Take note: Well-formulated serums absorb quickly and disappear into your skin. If they leave an oily or sticky residue, they're not doing their job well.
You can use your serum(s) both morning and night. They do not necessarily replace your moisturizer but can boost the hydrating effects of your moisturizer. Moisturizers have a simpler job; they are meant to hydrate the skin and prevent water loss.
If your skin's happy with serum alone, you can skip moisturizer. But only a lucky few with normal and super oily skin can get away with this, in my experience. So, don't be too disappointed if your skin needs both.
Retinol and Hyaluronic Acid
“AHA, BHA, retinol, and benzoyl peroxide can be mixed with moisturizing ingredients like hyaluronic acid, ceramides, and rosehip oil to get effective results — just ensure you are not using retinol as well as AHA or BHA's during the day," says Graf.
“You can't use it in too many products, or it will start to draw water from the skin,” she says.
Retinoids and serums can be used together, especially if the serum is soothing or hydrating. Be careful using very aggressive face oil serums with retinoids.
You can mix serums together in the palm of your hand before massaging them into your skin. This works best if all the serums are of the same consistency – otherwise, they won't blend together super smoothly, and you might end up with serums that feel (excuse this word), curdled.
Once your vitamin C serum has dried down, apply moisturizer. This order is crucial because applying moisturizer before your serum could block your skin from absorbing all of its goodness. If applying in the morning, follow with a broad-spectrum sunscreen with an SPF 30 or higher.
If you are applying a Vitamin C serum and hyaluronic acid separately, it's suggested that you apply the Vitamin C first, and then add the hyaluronic acid afterward in order to help fortify the skin barrier and lock in the moisture.
While hyaluronic acid can't fill in visible acne scars, it can help reduce redness and the visible appearance of acne. In addition, hyaluronic acid can help protect the skin, which is especially helpful for acne-prone skin, as it typically doesn't have a very strong lipid barrier.
Apply hyaluronic serums after cleansing (and toning, if you use a toner). Moisturizers go over the top. During the day, your SPF will be your last skincare step. Most people notice a difference in how their skin feels immediately after applying a hyaluronic acid product.
While some skincare ingredients, like retinol, are best used at night and others, like vitamin C, work their magic in the daytime, hyaluronic acid can be used both morning and night. “I recommend use of an HA serum up to twice daily, depending on your skin's needs,” says Abdulla.
"Hyaluronic acid can draw moisture from the air and keep your skin moist, holding almost 1000 times its weight in water," she says. "So, it's not only a moisturizer, it has the ability to hold extra moisture."
Hyaluronic acid hydrates and plumps up skin, giving you a youthful and radiant glow. By brightening the skin, it can help mask darkness under the eyes. “Hyaluronic acid and glycerin help pull moisture into the epidermis from the environment above and dermis below,” Waldorf says.
