Ingredient breakdown
INGREDIENTS5-Ceramide Complex ~3-5%Proven
A comprehensive blend of five ceramide types (EOP, NS, NP, AS, AP) that mimic the skin's natural lipid barrier. Ceramides make up 50% of the lipids in our skin barrier and are essential for maintaining hydration and protecting against environmental damage.
- Ceramide EOP (0.85-1.3%): Most abundant, supports overall barrier integrity
- Ceramide NS (0.5-1.2%): Helps form protective layer
- Ceramide NP (0.45-1%): Known for water retention properties
- Ceramide AS & AP: Less common ceramides for comprehensive repair
Aquatide (Heptasodium Hexacarboxymethyl Dipeptide-12)Patented
An award-winning patented peptide that won the In-Cosmetics Asia Gold Medal. Unlike topical ceramides that work on the surface, Aquatide stimulates skin cells to produce their own ceramides from within, promoting long-term barrier health.
- Mechanism: Activates autophagy in skin cells to boost natural ceramide production
- Clinical Studies: Shown to increase skin's natural ceramide levels
- Dual Action: Works synergistically with topical ceramides for inside-out and outside-in repair
Panthenol (Pro-Vitamin B5) 1.2-1.8%Proven
A multi-functional ingredient that provides deep hydration, soothes inflammation, and supports skin barrier repair. At this concentration, it effectively reduces redness and helps heal irritated skin.
- Humectant: Attracts and binds water to keep skin hydrated
- Anti-inflammatory: Reduces irritation from harsh ingredients
- Wound Healing: Promotes fibroblast proliferation for faster repair
Biosaccharide Gum-1 0.3-0.7%Promising
A plant-derived polysaccharide that provides immediate soothing benefits and long-lasting hydration. Calms redness and smooths skin texture while protecting against environmental stressors.
- Source: Derived from plant fermentation
- Benefits: Anti-inflammatory, moisturizing, skin-smoothing
Supporting Barrier IngredientsEssential
The formula includes cholesterol and phytosphingosine, which together with ceramides form the "holy trinity" of skin barrier repair. This 3:1:1 ratio mimics the natural composition of healthy skin.
- Cholesterol: Essential lipid that maintains barrier flexibility
- Phytosphingosine: Antimicrobial properties, helps fight acne-causing bacteria
- Glycerin (3.5-5.3%): Powerful humectant for surface hydration

How to use
HOW TO USEDispense Product
After cleansing and toning, pump 1-2 drops of serum onto your fingertips. A little goes a long way - one pump is enough for the entire face and neck.
Apply to Face
Gently spread the serum across your face and neck, avoiding the eye area. The milky gel texture glides smoothly without tugging.
Press and Absorb
Use the warmth of your palms to gently press the serum into your skin. This enhances absorption and helps the ceramides penetrate deeper.
Follow with Moisturizer
Once absorbed (10-15 seconds), follow with your moisturizer to seal in the benefits. In summer, this serum alone may be sufficient for normal skin.

Frequently asked questions
FAQYes, this serum is safe for use during pregnancy and breastfeeding. It does not contain any ingredients of concern such as retinoids, salicylic acid, hydroquinone, or chemical sunscreens. The formula is gentle, fragrance-free, and dermatologist-tested, making it suitable for the increased skin sensitivity many experience during pregnancy.
No, this serum is NOT fungal acne safe. It contains several potential Malassezia triggers including Sorbitan Sesquioleate, Pentaerythrityl Tetraisostearate, Cetearyl Alcohol, Stearic Acid, and Glyceryl Stearate. If you're prone to fungal acne, consider alternatives like Etude House SoonJung 2x Barrier Cream or products specifically labeled FA-safe.
Yes! This serum is actually excellent to use with active ingredients. Many users apply it before retinol or tretinoin to buffer irritation while still allowing the active to penetrate. For vitamin C, apply the vitamin C serum first, let it absorb, then follow with this ceramide serum. For AHAs/BHAs, you can use this serum after to soothe and replenish the skin barrier.
This serum is best suited for dry, dehydrated, sensitive, and mature skin types. It's specifically formulated for compromised skin barriers. Those with combination skin can use it effectively, especially in dry seasons. Very oily skin types may find it slightly rich—consider using only at night or look for a gel-based alternative.
You'll feel immediate hydration and soothing upon application. Visible improvement in dryness and flaking typically occurs within 1-2 weeks. Noticeable barrier strengthening and reduced sensitivity to actives takes about 3-4 weeks of consistent use. For long-term skin health improvement, expect to see optimal results after 6-8 weeks of daily use.
Apply this serum after cleansing and toning, before heavier treatments and moisturizer. The general order is: Cleanser → Toner → This Serum → Treatment Serums → Moisturizer → Sunscreen (AM). If using retinol, you can apply this serum before the retinol as a buffer, or after to soothe.
This serum has a low comedogenic rating of 1/5, meaning it's unlikely to clog pores. User reviews consistently report that it does not cause breakouts, even on acne-prone skin. The lightweight, milky gel texture absorbs quickly without leaving heavy residue that could block pores.
The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal efficacy. The 30ml bottle typically lasts 2-3 months with twice-daily use (1 pump per application). Store in a cool, dry place away from direct sunlight to maintain product integrity.
Verdict: The Celimax Dual Barrier Boosting Serum is an excellent choice for anyone seeking comprehensive barrier repair with its unique 5-ceramide complex and patented Aquatide peptide. The fragrance-free, gentle formula makes it ideal for sensitive and dry skin types, and it works beautifully as a buffer for retinol users. While the small bottle size and lack of fungal acne safety are drawbacks, the science-backed formulation and positive user reviews make this a solid investment for barrier health. Best suited for those who prioritize ingredient quality over value-per-ml and need targeted ceramide therapy for compromised skin.

Understanding Parabens
Parabens are a large group of preservatives which are used to prevent bacteria growing in cosmetic formulations. There has been some healthy controversy surrounding them due to a few studies finding paraben presence in breast tumours and breast tissue.

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.
