Hydraluron Moisture Serum
Hydraluron Moisture Serum
Product Description
Product overview
A lightweight, water-based hydrating serum featuring low molecular weight hyaluronic acid and red marine algae to deliver deep, long-lasting moisture beneath the skin's surface for a plumper, dewier complexion.
Deep Hydration Delivery
Low molecular weight hyaluronic acid penetrates beneath the skin's surface to deliver moisture at deeper levels, unlike standard HA that sits on top.
Texture & feel
SENSORYDeep Hydration Delivery
Low molecular weight hyaluronic acid penetrates beneath the skin's surface to deliver moisture at deeper levels, unlike standard HA that sits on top.
1000x Water Retention
Hyaluronic acid holds up to 1,000 times its weight in water, acting like a moisture sponge to keep skin plump and hydrated throughout the day.
Red Marine Algae Booster
Ahnfeltia Concinna Extract gently stimulates circulation, enhancing the delivery and penetration of hyaluronic acid into the skin.
Minimalist Clean Formula
Only 13 ingredients — no oils, fragrances, silicones, parabens, or sulfates. Gentle enough for the most sensitive and reactive skin types.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. All ingredients are considered safe for use during pregnancy and breastfeeding.
Free from ferments, fatty acids, esters, polysorbates, and oils that feed malassezia yeast. Confirmed fungal acne safe by multiple ingredient checkers.
Zero comedogenic ingredients detected. This oil-free, lightweight gel formula will not clog pores or contribute to breakouts.
Fragrance-free and alcohol-free with a minimal ingredient list. Suitable for sensitive and reactive skin. Patch test recommended for very reactive skin.
Can be safely layered with retinol, vitamin C, AHAs, and BHAs. Apply Hydraluron first to hydrate, then follow with actives.
As a humectant-only serum, it draws moisture but needs an occlusive layer on top to lock hydration in. Without moisturizer, it may feel drying over time, especially in low-humidity environments.
Ingredient breakdown
INGREDIENTSSodium Hyaluronate (Low Molecular Weight) ~3.4–5.1%Proven
The sodium salt form of hyaluronic acid — a powerful humectant naturally found in the skin that can hold up to 1,000 times its weight in water. The low molecular weight version used here allows deeper penetration beneath the skin's surface for enhanced hydration from within.
- Function: Humectant that draws and retains water in the skin, improving hydration, plumpness, and elasticity
- Molecular Weight: Low MW variant penetrates deeper than standard HA, reaching lower layers of the epidermis
- Research: Extensively studied; topical HA has been shown to significantly improve skin hydration and reduce the appearance of fine lines
Ahnfeltia Concinna Extract (Red Marine Algae) ~1.0–1.5%Promising
A nutrient-rich red marine algae extract that acts as a skin protectant and helps enhance the delivery of other active ingredients. It mildly stimulates circulation, allowing hyaluronic acid to penetrate the skin more effectively.
- Function: Skin protectant, penetration enhancer, and humectant with potential antioxidant properties
- Mechanism: Stimulates mild circulation to boost absorption of HA into deeper skin layers
- Additional Benefits: Also helps thicken the product texture and provides supplemental hydration
Propanediol ~5–10%Proven
A plant-derived (typically from corn) multi-functional ingredient that improves skin moisturization, acts as a solvent, and enhances the sensory feel of the formula. It helps other ingredients absorb more efficiently into the skin.
- Function: Moisturizer, solvent, absorption enhancer, and preservative booster
- Safety: Very low irritation potential; widely considered safe for all skin types including sensitive skin
- Origin: Typically derived from corn sugar via fermentation — a sustainable, bio-based alternative to petroleum-derived glycols
13 ingredients
Water (Aqua/Eau), Propanediol, Sodium Hyaluronate, Carbomer, Butylene Glycol, Sodium Hydroxide, Ahnfeltia Concinna Extract, Disodium EDTA, Chlorphenesin, Sodium Dehydroacetate, Sodium Benzoate, Sorbic Acid, Phenoxyethanol.
Where it fits in your routine
ROUTINEApply to damp skin after cleansing/toning for best absorption. Always follow with a moisturizer to seal in hydration. Use both AM and PM.
How to use
HOW TO USECleanse & Prep
Start with a clean face. For optimal results, leave skin slightly damp after cleansing or toning — hyaluronic acid works best when it has water to draw from.
Apply a Pea-Sized Amount
Dispense a pea-sized amount of serum onto your fingertips. Gently press and pat it across your entire face and neck, avoiding the eye area.
Let It Absorb
Wait 15–30 seconds for the serum to fully absorb. The lightweight gel texture sinks in quickly without leaving residue or stickiness.
Seal with Moisturizer
Follow immediately with a moisturizer (or Hydraluron Moisture Jelly) to lock in hydration. This occlusive step is essential to prevent moisture evaporation.
Who is it for?
WHOPerfect for you if:
- Your skin feels dehydrated, tight, or flaky
- You want a lightweight hydration booster under your moisturizer
- You have sensitive skin and need a minimal, fragrance-free formula
- You're looking for a pregnancy-safe and fungal acne-safe serum
- You want to plump fine lines and improve skin texture
- You prefer clean beauty with a short, transparent ingredient list
Consider alternatives if:
- You need a standalone moisturizer — this requires a cream on top
- You live in a very dry/arid climate (humectants may pull moisture from skin without proper layering)
- You want multiple molecular weights of HA for layered hydration
- You prefer a multi-active serum with additional ingredients like niacinamide or peptides
- You need a larger bottle size — 30ml can run out quickly with twice-daily use
Skin type compatibility

Frequently asked questions
FAQYes. Hydraluron Moisture Serum contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or any other ingredients flagged as unsafe during pregnancy or breastfeeding. The formula consists of hyaluronic acid, red marine algae, and basic stabilizers/preservatives — all considered safe for expecting and nursing mothers. As always, consult your healthcare provider if you have specific concerns.
Yes. The formula is confirmed fungal acne safe by multiple ingredient analysis tools. It contains no fermented ingredients, fatty acids, esters, polysorbates, or oils that are known to feed malassezia yeast. This makes it one of the safest hyaluronic acid serums available for those prone to fungal acne or pityrosporum folliculitis.
Absolutely. Hyaluronic acid is one of the most compatible ingredients in skincare and can be layered with virtually any active, including retinol, vitamin C (L-ascorbic acid), AHAs (glycolic, lactic acid), and BHAs (salicylic acid). Apply Hydraluron first on damp skin to hydrate, wait for it to absorb, then apply your treatment actives. It can also help buffer potential irritation from stronger actives by keeping skin hydrated.
Hydraluron is formulated for all skin types. It is particularly excellent for oily, combination, sensitive, and acne-prone skin due to its oil-free, fragrance-free, lightweight gel texture. Dry skin types will also benefit, though they should pair it with a rich moisturizer on top. Its minimal 13-ingredient formula makes it especially well-suited for sensitive and reactive skin that cannot tolerate complex formulations.
Many users report immediately softer, smoother skin after the first application. Noticeable improvements in plumpness and hydration levels typically appear within 1–2 weeks of consistent twice-daily use. Fine line reduction and overall radiance improvements become more visible after 4–6 weeks of daily use paired with a moisturizer.
Apply Hydraluron after cleansing and toning, but before treatment serums (like retinol or vitamin C) and moisturizer. The general rule is thinnest to thickest consistency. Apply to damp skin for maximum hydration, let it absorb for 15–30 seconds, then follow with your other products. Always finish with moisturizer (AM and PM) and sunscreen in the morning.
No. Hydraluron Moisture Serum has a comedogenic rating of 0 out of 5. Independent ingredient analysis has found zero comedogenic ingredients in the formula. It is oil-free, silicone-free, and water-based, making it extremely unlikely to clog pores or cause breakouts. It is safe for acne-prone skin.
The serum has a Period After Opening (PAO) of 12 months. With twice-daily use of a pea-sized amount, the 30ml tube typically lasts approximately 6–8 weeks. Store in a cool, dry place away from direct sunlight to maintain efficacy throughout the PAO period.
Verdict: Indeed Labs Hydraluron Moisture Serum is an excellent, no-fuss hydrating serum that does one thing exceptionally well — it delivers hyaluronic acid deep into the skin with a clean, minimalist formula. Its ultra-short ingredient list (just 13 ingredients), fungal acne safety, pregnancy safety, and zero comedogenic rating make it a standout for sensitive and acne-prone skin. The addition of red marine algae to boost HA penetration is a clever touch, even if clinical evidence for that claim is limited. Where it loses points is value — at $24.99 for 30ml with a single molecular weight of HA and no additional actives, competitors like The Ordinary HA 2% + B5 offer more for significantly less. It also cannot work alone and requires a moisturizer on top. Best for minimalists who want a reliable, safe, no-frills hydration booster to prep skin before their moisturizer.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue.

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.

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 «promises» 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.
