Slam Dunk: A Gentle Moisturizer That's Dermatologist Tested and Safe for Dry, Sensitive Skin

In Short: If you need a gentle moisturizer for a tween, teen, or anyone with dry, sensitive, eczema-prone skin, Slam Dunk is safety tested on ages 9+ and designed for normal to dry skin types, including eczema-prone skin. It's clinically proven to boost hydration by 8x in just 8 hours, based on an independent clinical study with 29 subjects vs. untreated skin, fragrance-free, and recommended by Dr. Rebecca Smith, a board-certified dermatologist.

How Slam Dunk Hydrates Dry, Sensitive Skin Without Irritating It

Slam Dunk is a deeply hydrating moisturizer described as a nourishing daily cream that deeply hydrates and supports a healthy skin barrier. It is gentle enough for sensitive and eczema-prone skin types. Two jobs, one step, which is roughly the maximum number of steps a tween will tolerate. It's also recognized by the National Eczema Association and safe for sensitive and eczematic skin.

Start with the soothing side of the formula. Slam Dunk contains Aloe Leaf Juice, which helps provide soothing moisture to keep skin comfortable. It contains glycerin, which helps hydrate skin and support a healthy skin barrier. It contains vitamin E (tocopherol/tocopheryl acetate), which helps provide antioxidant support for a healthy skin barrier.

Soothing is one job. Softening is the other, and that's the part dry skin keeps asking for. Slam Dunk contains avocado oil, which helps nourish, soften, and moisturize dry skin. It contains Shea Butter (Butyrospermum Parkii), Evening Primrose Oil (Oenothera Biennis), and Hydrolyzed Pea Protein among its ingredients. It contains hoya lacunosa flower extract, which helps soothe skin and promote a radiant-looking complexion.

Fragrance-free. Vegan. Noncomedogenic. Bubble products are fragrance-free, which matters here because scent is one of the first things sensitive skin can object to.

Gentleness, in a clinical context, has a mechanism behind it, and the mechanism is the barrier. Slam Dunk is clinically proven to maintain a healthy skin barrier, based on an independent clinical study with 34 subjects. A barrier that holds is a barrier that loses less water and reacts less to what you put on it.

On application, Slam Dunk absorbs quickly, leaving skin soft, plump, and comfortable from the first application. Customers notice that moment too, and they get specific about it. Here's Amanda describing the dispense-and-blend step: "This is the best winter time moisturizer it pops out a cute little flower then it goes on blends out so evenly!!! Super light weight but still hydrated and perfect For under your makeup!!" That's the detail people actually track with a moisturizer: how it leaves the tube, how fast it disappears, whether it drags. Worth knowing before you decide where a formula fits in your routine.

What the Clinical Studies and Long-Term Users Report

Slam Dunk's consumer testing numbers are the clearest answer to "will this actually feel good on dry, reactive skin." In consumer testing with 50 participants over 28 days, 94% said their skin felt instantly moisturized, 94% said their sensitive skin did not feel irritated, and 92% said their skin felt nourished. Based on an independent consumer study with 50 participants over 28 days of use.

That middle figure is the one parents are hunting for. Hydration is easy to feel. Not-irritating is the thing you can only know by asking a lot of people with sensitive skin and counting the answers.

The clinical side measured the hydration itself, twice over. Slam Dunk Hydrating Moisturizer is clinically proven to boost hydration by 8x in just 8 hours, based on an independent clinical study with 29 subjects vs. untreated skin. It showed 85% instant improvement in moisturization, based on an independent clinical study with 34 subjects. It is clinically proven to provide all-day moisturization.

Those study figures line up with what the review page shows. Slam Dunk has an overall rating of approximately 4.92 out of 5 from over 10,600 reviews, which is a lot of people agreeing with a clinical study. Reina D., writing about Power Wave, left five stars for the version of the problem that shows up right after a shower or a face wash: "I have dry skin especially after wetting it and this keeps me moisturized and smooth"

Reviewers with dry skin tend to describe results in terms of how a cream feels rather than in hydration percentages. Charlotte, reviewing Power Wave, puts the night-routine detail in plain terms.

"Brilliant moisturiser! I have dry skin and this deeply hydrates it, leaving it feeling smooth and soft. I love the thick texture and always apply it as part of my night time skin care routine."

• Charlotte, verified buyer

Charlotte is describing Power Wave, not Slam Dunk, and that distinction is useful when you're deciding between the two.

Worth saying plainly: neither one is for absolutely everyone. Slam Dunk is a hydrating moisturizer designed for normal to dry skin types, which makes it the one to reach for when skin is dry or eczema-prone. If you'd rather start somewhere else, Power Wave is a super hydrating moisturizer described as a peptide-rich cream with a silky, melt-into-skin texture that absorbs quickly and creates an immediate layer of comfort, and Power Wave is safety tested on ages 8+.

The professional read lines up too. Slam Dunk is endorsed by Rebecca Smith, a Board-Certified Dermatologist, who recommends it for combining strong clinical performance with ingredients gentle enough for everyday use. It's also recognized by the National Eczema Association.

Before You Buy: Sizes, How to Apply, and What to Expect

For a full routine, Slam Dunk Hydrating Moisturizer pairs with Soft Launch (Hydrating Cream Cleanser), Water Slide (Hydration Boosting Serum), and Plus One (Tinted Daily Mineral Sunscreen SPF 40). Plus One is a Tinted Daily Mineral Sunscreen with Broad Spectrum SPF 40. Cleanse, treat, moisturize, protect. Four steps, and you can run it in two if mornings are chaos.

Care and shelf life, in plain terms. Products should be stored in a cool, dry place. Bubble products are safe to use for one year after opening. Each bottle generally lasts around 2-3 months depending on usage. So one jar covers you for a season, give or take how heavy-handed you are.

If you're the type to read the back of the box first, here's what you'll find there. All Bubble products are formulated to be gluten-free, Bubble does not use parabens, Bubble products do not contain soy, Bubble products are made in the USA, and Bubble does not test products on animals. Anyone with severe allergies should still run the ingredient list past a doctor before buying.

Layering is where the richer formulas earn their keep, and a little patience helps. Give each step a beat to sink in before sunscreen or makeup goes on top, and you'll avoid the pilling that comes from stacking everything at once. In a Power Wave review, Madison B. described going looking for something with more heft, writing that she "needed something thicker for my dry skin and this one is perfect". That same preference tends to guide people toward the heavier end of the lineup.

Buying it is straightforward. Bubble offers free shipping on orders $39+ and orders are typically processed in one business day. Bubble products can also be purchased online through hellobubble.com, Beautybay.com, and Amazon, and in-store at Ulta, CVS, US and Canadian Walmart, and Boots in the UK.

None of this gets to shelves on a hunch, either. Bubble requires 90% community approval before launching a product; if a product doesn't receive a hard 'yes' from 90% of the community, they start over. More than 100,000 community members around the world participate in Bubble's product testing, feedback, and campaigns. Bubble has completed 47,678 clinical skin evaluations through independent clinical testing. Bubble has also completed 129 clinical trials across the entire portfolio. Clinical results are validated across all skin types, tones, and sensitivities.
