Hyaluronic acid works best when you use both the serum and the cream, because each has a different job: the serum delivers it to the skin, and the cream holds in hydration and makes it last longer. It suits all skin types.
Hyaluronic acid is the best-known hydrating ingredient, and you’ll find it almost everywhere: serums, creams, masks. The question is inevitable: should you choose a serum or a cream? The short answer is that they do two different jobs. Let’s see what they are.
What is hyaluronic acid?
It’s a molecule found naturally in the skin, able to bind and hold water. Over time, its levels tend to decrease, and the skin can look less hydrated and less smooth.
How it works on your face
In cosmetics, hyaluronic acid is a humectant: it attracts water and helps the skin hold on to it. The result is skin that looks more hydrated, softer and smoother.
The molecular weight matters too:
- hyaluronic acid with a high molecular weight stays on the surface and forms a film that limits water loss;
- the kind with a low molecular weight is made of smaller molecules, which hydrate the layers of the skin more deeply.
Many formulas combine the two.
Serum or cream: the differences
- The serum has a light texture and a higher concentration of actives: it brings hyaluronic acid to the skin straight after cleansing.
- The cream combines hyaluronic acid with emollient ingredients, which help maintain hydration for longer.
They’re not in competition: the serum hydrates, the cream keeps it that way. Used one after the other, they complement each other.
Which skin types it suits
Hyaluronic acid suits all skin types, because combination and oily skin need hydration too, not just dry skin. What changes is the texture: lighter for combination and oily skin, richer for dry and mature skin.
Which ingredients it pairs with
- Niacinamide, for the skin barrier.
- Peptides, in treatments designed for tone and elasticity.
- Vitamin C, for radiance.
- Retinol or bakuchiol, as it softens the drying effect they may have.
Three myths about hyaluronic acid
“It dries out your skin”
It only happens in one case: when you use it on its own in a very dry environment. Without a cream on top, the water it draws to the surface evaporates and the skin can feel tighter than before. To avoid this, just always apply a cream straight after.
“The more concentrated, the better”
No. Above a certain percentage, the formula becomes sticky without hydrating any more. What matters is the quality of the formula and consistent use.
“Drinking it is enough”
Hyaluronic acid is also found in some supplements, but a supplement and a cosmetic work on different levels: one doesn’t replace the other. We talk about this in collagen and hyaluronic acid: the differences.
Hyaluronic acid in Mialica products
With the Mialica Linea Viso you don’t have to choose: hyaluronic acid is in both the Face Serum, with peptides, bakuchiol and niacinamide, and the 24H Face Cream, with niacinamide, peptides and exosomes. Apply them in sequence, morning and evening: first the serum, then the cream.
For your routine from within, each vial of Collagen PRO5 also contains 100 mg of hyaluronic acid.
Frequently asked questions
Can you use hyaluronic acid every day?
Yes, morning and evening, even in summer.
Is it suitable for oily skin?
Yes: it hydrates without leaving skin greasy. Choose a light texture.
How long before you see results?
You can feel the hydration straight after applying it. For smoother-looking skin, it takes consistent use over a few weeks.
In summary
Serum or cream? Both. The serum brings hyaluronic acid to the skin, the cream helps it stay there. Apply it to slightly damp skin, morning and evening, and always finish with the cream.
