Neutrogena Hydro Boost

The famous hyaluronic acid gel — in which hyaluronic acid is the 15th ingredient of 20 and silicone is the second.

At a Glance

Mixed

Hydro Boost contains less hyaluronic acid than its name suggests. Ingredients are usually listed from most to least. In this gel, dimethicone (a silicone) is second, while hyaluronic acid is fifteenth of twenty — below the thickener and the preservative.

That means the silicone film and glycerin do most of the work you feel. That film is genuinely pleasant and hydrating, so the product performs — it just does not perform because of the ingredient in its name.

If you like it, that is fine. Choose the fragrance-free version to skip the added scent and dye, which add allergy risk without adding skincare benefit.

Key facts

How it works

It feels genuinely excellent, and that is not nothing — the moisturizer you enjoy using is the one you keep using. The gel texture is light, cooling, absorbs fast, and works well under makeup.

For oily and combination skin that finds creams suffocating, this solved a real problem, and it is popular for a reason.

First, a rumor worth killing: Hydro Boost was not part of the 2021 benzene recall. That recall covered five aerosol sunscreen sprays — Hydro Boost is a moisturizer with no SPF and was never in scope. Independent testing that flagged benzene elsewhere put a Hydro Boost product on its safe list. If you have been avoiding it for that reason, you do not need to.

Everyday habits

How to use it

When: Morning and night (AM and PM).How much: A pea-sized amount for the face. It is a light water gel. Steps: Apply to slightly damp skin after cleansing. Layer it over any serums or actives. Tip: For daytime, its light finish sits well under sunscreen and makeup.

Who should be careful+

The product is named for hyaluronic acid. Hyaluronic acid is the 15th ingredient out of 20 — below the carbomer, below the preservative. Dimethicone is second, ahead of glycerin.

So: the silicone is doing the work, and the hero ingredient is a trace. What you feel is a silicone film and glycerin. That film is genuinely pleasant and genuinely hydrating — but you are not buying what the name is selling.

The main version contains fragrance and Blue 1 dye. For a product marketed on skin health, adding a dye is a purely cosmetic decision with a real, if small, allergy cost. A fragrance-free version exists — buy that one.

It has not been reformulated, despite what you may have read — the ingredient list is unchanged since 2017. But the SKUs have been reshuffled, and the fragrance-free "Gel Cream" is now positioned for dry skin. You may repurchase and receive a different, richer product than you remember.

Reviewers report tackiness and stinging more consistently than pilling.
