A dermatologist’s take

Eh.

Neutrogena Hydro Boost is a pleasant, lightweight gel for oily and combination skin, but not the hyaluronic acid product its name promises. Hyaluronic acid sits fifteenth of twenty; the silicone doing the work sits second. Buy the fragrance-free version. If your skin is dry, this gel is too light.

Pros

  • Good fit for oily skin
  • Good fit for normal skin

Cons

  • May be too light for very dry skin
  • Standard version contains fragrance

Skin fit

Who is it best for?

Visible sebum shine and natural pores on the nose and cheek.

Oily Skin

Good fit

Oily skin still loses water through the surface, and skipping moisturizer does not reduce oil. What it needs is water pulled in without a heavy seal on top.

This gel is light enough that oily skin will wear it every day, and it disappears under sunscreen and makeup.

Normal Skin

Good fit

Enough moisture for skin with no particular complaint. If your skin is genuinely dry, this gel is too light on its own.

Inflamed acne on light skin. The spots sit in a patch of pink, and the ring of redness around each one is easy to see. A few have a yellow-white head, and the skin between them is dry and flaking.

Acne

Okay fit

Benzoyl peroxide and retinoids dry the skin out, and that is why people quit them. A light, non-greasy moisturizer alongside them prevents that.

This one adds no oils, though the fragranced version is worth avoiding on irritated skin.

The front of one shin on pale skin. The surface is pink with fine white flaking and a few shallow cracks, and the skin around it is even in tone.

Dry Skin

Poor fit

Hyaluronic acid is sold as the fix for dry skin, and this is the gel most people start with. It holds water at the surface but has little to seal it in, so dry skin needs a cream with lipids over it.

Extreme close-up of light skin in an active eczema flare, too close to tell which part of the body it is. Blotchy pink-red inflammation covers the whole frame with no clear edge, with small raised bumps, fine dry scale and a few fresh scratch marks.

Eczema

Poor fit

No barrier repair, and the gel base can sting cracked skin. Use an ointment or a ceramide cream in a flare.

Feel & smell

What does it feel like?

HeaviestLightest

Gel

It is a water gel: light, cooling, absorbed in seconds with nothing left on the surface. Some find it slightly tacky as it settles, and some report stinging.

It sits well under sunscreen and makeup, and pilling is not a common complaint. It comes in a screw-top jar, so you dip fingers into it. The standard version contains fragrance and a blue dye; the fragrance-free version is the one to buy.

Inside the formula

What do the main ingredients do?

How this formula works.

A moisturizer has three moves: pull water into the outer layer, replace the fats that glue those cells together, or seal the surface. Neutrogena Hydro Boost does the first and the third and skips the second, because there are no ceramides in it.

Full clinical explanation

A moisturizer has three moves: pull water into the outer layer, replace the fats that glue those cells together, or seal the surface. Neutrogena Hydro Boost does the first and the third and skips the second, because there are no ceramides in it.

The pulling is done by glycerin and a long list of small humectants — sodium PCA, urea, trehalose and amino acids — several of which skin makes for itself. The sealing is done by dimethicone, a silicone that lays a breathable, non-greasy film across the surface.

That film is why the gel feels so good, and it is also where the name misleads. Hyaluronic acid is a trace ingredient, not the active. The formula works well for oily and combination skin, but you are buying a silicone and glycerin gel rather than the hyaluronic acid on the jar.

All ingredient roles

Glycerin

A small humectant. It moves into the outer layer of skin and holds water there.

Dimethicone

A silicone that smooths the surface and adds to the protective film.

Sodium Hyaluronate

A form of hyaluronic acid. Its molecule is large, so it stays on the surface and holds water there.

Water

The base the other ingredients are dissolved in. Most of it evaporates soon after the product goes on.

Ethylhexylglycerin

Helps the preservative work and softens the feel of the product.

Use & results

In your routine

How to use it.

01 / EVERY DAY

How much

A pea-sized amount for the face. It spreads a long way for a gel.

Tip

The light finish is the main reason to own it. It sits under sunscreen and makeup without rolling up.

02 / OVER TIME

What to expect

Skin feels hydrated immediately and stays that way as long as you keep applying. If your skin feels tight again a few hours later, this gel is too light for you.

Price spectrum

Where does the price fall?

Paying more doesn’t guarantee better results. A good buy is a formula with the right ingredients, strength and texture for your skin. Use price per ounce to compare cost, then weigh it against the pros and cons above.
