π¬ Ingredient Breakdown
π§ Hyaluronic Acid (Sodium Hyaluronate) 0.5% Β· 5 MW Proven
The hero of the formula: five molecular weights of HA draw water into different depths of the skin, from the surface down, for instant multi-level hydration and a plumper, smoother look.
- Source: Sodium hyaluronate is a clinically established humectant shown to increase skin hydration and improve elasticity and barrier comfort.
- How it works: Holds many times its own weight in water, binding moisture within the upper layers of skin.
β¨ Niacinamide (Vitamin B3) ~2% (est.) Proven
Smooths rough, bumpy texture, supports the skin barrier and helps even out tone. A multitasking favorite for KP-prone and uneven body skin.
- Source: Topical niacinamide is well supported by research for improving barrier function and the look of uneven tone, typically at 2β5%.
𧱠Ceramide NP <1% Proven
An identical-to-skin lipid that helps rebuild and seal the moisture barrier, reducing water loss so hydration lasts longer.
- Source: Ceramides are core components of the skin's natural barrier; topical ceramides are shown to support barrier repair.
πΏ Panthenol (Pro-Vitamin B5) Supporting Promising
A soothing humectant-emollient that calms and softens, often used to comfort dry, irritated or compromised skin.
- Source: Panthenol is widely used for its hydrating and skin-soothing properties in barrier-support formulas.
π Gluconolactone (PHA) Supporting Promising
A gentle polyhydroxy acid that lightly exfoliates and smooths while attracting moisture β milder and less irritating than AHAs, with added antioxidant benefits.
- Source: PHAs are larger molecules than AHAs, exfoliating the surface more gently and suiting sensitive skin.
𫧠Glycerin High (2nd listed) Proven
A classic, heavily-studied humectant that pulls and holds water in the skin for reliable, all-day baseline hydration.
- Source: Glycerin is one of the most researched and effective humectants in skincare, supporting barrier function and hydration.

Cleanse & pat
Shower or cleanse, then pat skin until it's just slightly damp.
Dispense
Pump 2β4 times into your palms β use more for larger areas.
Massage in

π€ Who Is It For?
β Perfect for you if:
- You want lightweight, fast-absorbing hydration without grease
- You have dry, dehydrated, eczema-prone or sensitive skin
- You dislike fragrance or want a mixable, layerable base

- You like "skincare for the body" with proven actives
β Consider alternatives if:
- You're prone to fungal acne / malassezia (esters present)
- You have very dry skin and want all-in-one moisture (you'll likely still need a cream)
- You're on a tight budget β $45 is premium for a body product
- You want a rich, occlusive butter or a scented experience
π― Skin Type Compatibility
Gel-serum absorbs instantly with zero shine or heaviness.
Hydrates well but usually needs a cream layered on top for lasting moisture.
Light enough for oily zones, hydrating enough for dry patches.
Fragrance-free and accepted by the National Eczema Association; gentle and well-tolerated.
Non-comedogenic and oil-free, but esters mean fungal-acne-prone skin should patch test.

βοΈ Pros & Cons
β Praised
- Sinks in almost instantly β no greasy, sticky residue
- Genuinely hydrating; great for dry, dehydrated skin
- Fragrance-free and easily mixable with other products
- Loved for KP, strawberry legs and rough texture
- Clean, vegan formula with face-grade actives
- National Eczema Association Seal of Acceptance
β Criticized
- Expensive at $45 for a body product
- Not rich enough alone for very dry skin (needs a cream)
- Pump can leave product stuck at the bottom
- Contains esters β not ideal for fungal-acne-prone skin
π° Budget-Friendly Alternatives (Dupes)
HA, ceramides and a barrier-lipid complex in a gel-serum β very similar actives for less. It's a face serum, so you'll use more to cover the body.
HA + ceramides + vitamin B5, fragrance-free and barrier-focused. Cheaper but thicker and formulated for the face rather than the body.
Multi-weight HA + B5 at a fraction of the price. Lacks ceramide, niacinamide and panthenol, and the texture is tackier on the body.

β Frequently Asked Questions
Generally considered yes. It contains no retinoids, salicylic acid, hydroquinone or chemical sunscreens β just humectants (hyaluronic acid, glycerin, panthenol), niacinamide, ceramide NP and a gentle PHA (gluconolactone). As always, check with your doctor about your specific situation.
Use caution. It contains sucrose stearate, polyglyceryl-10 stearate and hydrogenated lecithin β fatty-acid esters that can potentially feed malassezia. If you're prone to fungal acne or seb derm, patch test on a small area first.
Yes. It's fragrance-free and pH-friendly, so it works as a hydrating base under or over actives. On the body it pairs nicely with retinol or exfoliating treatments to buffer dryness and keep skin comfortable.
It's best for dry, dehydrated, sensitive and eczema-prone skin, plus anyone wanting lightweight hydration. Oily and combination skin also love the non-greasy gel finish that absorbs instantly.
Softer, smoother skin is usually immediate. Texture improvements β like KP and rough patches β tend to show over 1β2 weeks, with plumper, healthier-looking skin after about 4 weeks of consistent daily use.
After cleansing or showering, on slightly damp skin, before any lotion, cream or oil. Use it alone for light hydration, or as a treatment step under a richer moisturizer for very dry skin.
It's brand-stated non-comedogenic with a low comedogenic profile (about 1/5). It uses lightweight coconut-derived alkanes and esters rather than heavy oils, so it's unlikely to clog pores for most people.
Around 12 months after opening (12M). The airless pump helps keep the formula stable and protected from air and contamination, which supports its shelf life.
Verdict: The Body Serum delivers exactly what it promises β genuinely lightweight, fast-absorbing hydration with face-grade actives: five molecular weights of hyaluronic acid, niacinamide, ceramide NP and a gentle PHA. It's a standout for dry, sensitive, eczema- and KP-prone skin, and an easy "slap-on-and-go" step after the shower. The trade-offs are the premium $45 price and the fact that very dry skin will still want a cream layered on top. Fungal-acne-prone users should patch test for the esters. For everyone else chasing soft, plump, comfortable skin, it earns its hype.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

EU Allergen-Free
EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
Fungal Acne (Molassezia) Safe
Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging Β«promisesΒ» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
