Key ingredients
| Glycerin | Provides core humectant support for lasting hydration. |
|---|---|
| Butyrospermum Parkii (Shea) Butter | Adds shea-butter emollience within the rich base to support comfort and softness in dry skin. |
| Persea Gratissima (Avocado) Oil | A moisturizing plant oil that supports emollient softness, without individually demonstrated product-study effects. |
| Oenothera Biennis (Evening Primrose) Oil | Adds lipid-rich emollience as one part of the cream, not a separate eczema treatment. |
| Tocopherol | Vitamin E in the formula provides antioxidant and conditioning context, not proof of blue-light damage repair. |

Value check
At the Budget tier, you pay for a nourishing fragrance-free cream with unusually specific published hydration testing, making it most valuable when you want richer everyday moisture rather than a weightless finish.

Bottom line
If you want a richer everyday cream for normal-to-dry skin, Slam Dunk provides strong Budget value and direct product-level hydration data. If you prefer a lightweight finish or need actual eczema treatment, another product is the better fit.
If your skin is normal or dry and you want a richer cream without moving into a high price tier, Bubble Slam Dunk Hydrating Moisturizer uses glycerin, shea butter, avocado oil, evening primrose oil and other emollients to support daily moisture. It also has published finished-product hydration results, making it a particularly evidence-supported Budget choice for its primary job.
The relevant limitation is texture and scope: this is a comfortable daily moisturizer, not a treatment for eczema, skin aging or blue-light damage. If you prefer weightless hydration, a gel-cream may be a better fit than a richer lotion.

What it claims
Bubble describes Slam Dunk as a fast-absorbing, deeply hydrating cream for normal-to-dry skin that helps support comfort and the moisture barrier. It positions the formula as suitable for sensitive and eczema-prone skin and identifies it as noncomedogenic.[1]
The brand reports an eightfold hydration increase after eight hours compared with untreated skin in an independent 29-subject study, plus an 85% immediate improvement in moisturization in a separate independent study of 34 subjects. In a 28-day consumer study of 50 participants, 94% said their skin felt instantly moisturized, 94% said their sensitive skin did not feel irritated, and 92% said their skin felt nourished. These are distinct study types and brand-published results, not percentages you should expect personally or proof of treating an underlying skin disease.[1]
Claims vs. formula
Glycerin appears third in the complete INCI and supplies water-binding support. Isononyl isononanoate, heptyl undecylenate and caprylic/capric triglyceride create a spreadable emollient base, while cetyl alcohol, shea butter, avocado oil and evening primrose oil give the cream a more substantial skin-softening character.
Independent skin-care research documents glycerol’s role in stratum-corneum hydration and barrier function. That evidence supports the ingredient’s purpose, while Bubble’s own published finished-product studies are the appropriate basis for the cream’s specific eight-hour and immediate hydration claims.[2]
The currently published official brand INCI identifies aloe leaf juice powder, chamomile flower extract, Hoya lacunosa flower extract, arginine and hydrolyzed pea protein. Those ingredients add conditioning context, but Bubble’s hydration measurements do not isolate any one botanical’s effect or establish that the cream repairs visible redness, prevents eczema flares or reverses environmental damage.[3]
Tocopherol and tocopheryl acetate provide vitamin E ingredients, commonly used for antioxidant and skin-conditioning purposes. Ingredient presence alone is not proof of the finished product’s claimed protection from blue light or clinical reduction in photoaging.
Ingredients that matter
Glycerin binds water, while shea butter, avocado oil and evening primrose oil reinforce the comfort-focused emollient system. The balance of humectants and oils explains why Slam Dunk is intended for normal-to-dry skin and is more substantial than a weightless gel.
Aloe-derived juice powder and chamomile extract add conditioning ingredients, but do not change the fact that the strongest direct evidence is measured hydration. The finished-product tests cannot tell you which ingredient caused each observed effect.
The official INCI does not list fragrance, essential oils, retinoids, added color or silicones. The brand’s noncomedogenic statement is relevant if your skin is acne-prone, but no moisturizer has a zero-breakout guarantee for every individual.
Glycerin
If your skin feels dry or tight, glycerin helps your skin hold moisture. You don't need a high percentage or a separate serum when your moisturizer already works well.

Shea butter is a well-established emollient and occlusive used to soften dry-feeling skin and add richness to moisturizers. Its value depends on the complete formula, not the ingredient name alone.

Read the IngredientBriefSafety and regulatory context
Bubble says Slam Dunk is gentle enough for sensitive and eczema-prone skin, supported by its reported consumer-tolerance study. This is useful suitability context, not an eczema-treatment claim; the moisturizer does not substitute for a clinician-recommended regimen when your skin is inflamed or actively flaring.[1]
Bubble recommends use after toner or serum, morning and evening, before sunscreen in a daytime routine. The product itself does not provide an SPF rating and is not a sunscreen.[1]
What to expect in the short term
You get a cream that spreads easily and softens the surface of dry-feeling skin. Bubble’s independent-study summaries support higher measured moisture after application and at eight hours versus untreated skin, although the public summaries do not independently establish comparative performance against another finished moisturizer.
What to expect over time
With consistent use, expect the principal benefit to remain hydration and skin comfort. The 28-day consumer data gives relevant feedback about how participants experienced the cream, but does not prove long-term reversal of sensitivity, eczema or a damaged barrier.
If you need additional occlusion, compare a denser barrier cream; if Slam Dunk feels too rich, a lighter gel-cream may make daily application more pleasant.
Who it fits
This makes the most sense if your skin is normal, dry or sensitive and you prefer a nourishing cream without listed fragrance. It is also a reasonable moisturizer to consider for acne-prone skin because Bubble explicitly calls the finished product noncomedogenic, while reminding you that it is not an acne treatment.
If your skin is very oily, or you dislike emollient-rich formulas, a lighter option may fit better. If eczema is your main concern, the brand’s sensitivity testing is not evidence that this cream is a medicated eczema treatment.
Bubble includes Slam Dunk in its official vegan moisturizer collection and states in its brand FAQ that it does not test products on animals. These are current manufacturer declarations, not evidence of an independent certification for this exact product.[4][5]
Compare before you buy
Choose Slam Dunk when you want a Budget cream for normal-to-dry skin with a richer emollient mix and specific brand-published clinical hydration tests. This direct finished-product information is more useful than an unsupported promise based on a botanical alone.
Choose a lightweight gel-cream if your skin is oily or you dislike the texture of nourishing oils and butter. If you want medical eczema treatment or targeted anti-aging outcomes, a moisturizer’s hydration results are not sufficient evidence for those goals.
Final Assessment
Bubble Slam Dunk Hydrating Moisturizer provides appealing Budget value when your skin needs a comfortable, richer daily cream, backed by two separately described independent hydration studies and a 28-day consumer-tolerance study. Its strongest benefits concern measured moisture and softness, not proven eczema treatment or blue-light repair; the noncomedogenic and sensitive-skin positioning is useful, but the weight of the finish remains an important fit consideration.
