๐ฌ Ingredient Breakdown
๐ฆ Bifida Ferment Lysate Base / High Proven
A postbiotic made by fermenting Bifidobacterium, rich in peptides, amino acids, vitamins and polysaccharides. Listed first (ahead of water), so it forms the hydrating base of the serum and is the brand's signature "probiotic" ingredient.
- In-vitro study: Boosted barrier proteins filaggrin, loricrin and involucrin and acted as an antioxidant against UV and pollution.
- Human study (2010): A 10% cream made sensitive, reactive skin noticeably less dry and harder to irritate over one month.
๐ Niacinamide (Vitamin B3) 2% Proven
A multitasking form of vitamin B3 that strengthens the barrier, helps regulate oil, refines the look of pores and gently evens out tone. Yepoda states the concentration is 2% โ a gentle, barrier-supporting dose rather than a high-strength brightening level.
- Mechanism: Converts to NAD in skin cells, supporting repair, collagen production and defense against environmental stress.
- Tolerance: Around 2% is effective for barrier support and even tone with very low irritation risk.
๐งฌ Copper Tripeptide-1 (GHK-Cu) ~0.1โ0.4% Promising
A copper-bound peptide known for supporting collagen, firmness and skin regeneration. A repair-focused active that fits the serum's "barrier hero" positioning.
- 1998 study: 7 of 10 participants showed increased procollagen after one month โ more than vitamin C, melatonin or tretinoin in the same test.
- Caveat: Human evidence is still limited and many studies are small or in-vitro; results are encouraging but not conclusive.
๐ง Sodium Hyaluronate ~0.1โ2% Proven
The salt form of hyaluronic acid and a powerhouse humectant that pulls water into the skin and binds it at the surface for plump, hydrated skin.
- Multi-weight benefit: Different molecular sizes hydrate at different depths; low-weight versions are linked to improved elasticity and barrier repair.
๐ Polyglutamic Acid <1% Promising
A fermentation-derived humectant often compared to hyaluronic acid that holds water at the skin's surface and may help support wound healing for a smoother, plumper look.
- Fun fact: The same substance gives the Japanese food natto its stretchy texture.
๐ฟ Lactobacillus Ferment Lysate <1% Promising
A second postbiotic with soothing properties. Helps calm redness and may help with signs of photoaging, though the evidence is still developing.
- FA-safe: Derived from bacteria, not yeast, and free of the fatty acid chain lengths that feed Malassezia.
๐ซง Glycerin Humectant Proven
A naturally skin-identical humectant that draws water into the outer layers of the skin. Non-irritating, compatible with nearly every ingredient and effective across all skin types.
- Barrier support: Helps restore hydration, elasticity and a healthy moisture balance.
๐ Cyanocobalamin (Vitamin B12) Trace Promising
The manufactured form of vitamin B12 with skin-soothing, antioxidant and barrier-protecting properties; it is also used topically to help calm irritation and atopic dermatitis.
- Bonus: Gives the serum its characteristic soft pink hue.

๐ค Who Is It For?
โ Perfect for you if:
- You want a gentle, fragrance-free daily serum for sensitive or reactive skin
- Your goals are barrier repair, hydration, calming redness and a more even tone
- You prefer a multi-tasking "all-in-one" formula over single high-strength actives
- You have acne-prone or fungal-acne-prone skin and need a safe option
- You value vegan, cruelty-free and refillable, low-waste packaging
โ Consider alternatives if:
- You want aggressive dark-spot fading โ 2% niacinamide is on the gentle side
- You are looking for high-strength actives like 10% niacinamide, retinoids or acids
- You dislike pipette/dropper packaging or want a larger bottle for the price
- You need a single-ingredient minimalist formula to isolate one active
๐ฏ Skin Type Compatibility
Oil-free, lightweight gel that absorbs fast and won't add shine; niacinamide helps balance the look of oil.
Layered humectants hydrate well, but very dry skin will want a richer moisturizer on top to seal it in.
Balances hydration and oil across different zones without feeling heavy or greasy.
Fragrance-free, allergen-free and rich in soothing postbiotics; patch test if extremely reactive.
Non-comedogenic and fungal-acne safe, with niacinamide to help calm and refine blemish-prone skin.

โ๏ธ Pros & Cons
โ Praised
- Lightweight gel texture that absorbs fast without stickiness
- Fragrance-free and gentle โ well suited to sensitive, reactive skin
- Multi-tasking blend: probiotics, niacinamide, peptides, HA and B12
- Visible glow, even tone and reduced redness within 3โ4 weeks for many users

- The glass pipette can be awkward to dispense from
- 30ml for ~โฌ25 feels pricey per ml versus some K-Beauty rivals
- Frequently sold out on the brand website
- No strong exfoliating or high-strength actives for advanced concerns
๐ฐ Budget-Friendly Alternatives (Dupes)
Also pairs gentle 2% niacinamide with soothing, antioxidant-rich propolis. Glowy and calming, but swaps Yepoda's probiotic ferments and peptides for honeybee-derived propolis and honey.
Much higher 10% niacinamide plus zinc for oil control, at a fraction of the price. Far simpler though โ no probiotics, peptides or B12, and can feel slightly tacky on some skin.
A straightforward, affordable 10% niacinamide + hyaluronic acid serum for blemishes and oil. Lacks the barrier-repair postbiotics and peptide complex of The Repair Hero.

โ Frequently Asked Questions
It is generally considered a safe choice. The formula contains no retinoids, salicylic acid, hydroquinone or chemical sunscreens, and relies on widely pregnancy-friendly ingredients such as niacinamide, peptides, hyaluronic acid, glycerin and probiotic ferments. As always, confirm with your doctor or midwife before adding any product during pregnancy or breastfeeding.
Yes. Independent checkers confirm it as fungal-acne safe. Its ferments are derived from bacteria (Bifida and Lactobacillus), not yeast, and the formula is free of the fatty acids, esters and polysorbates that typically feed Malassezia. This makes it a sensible option for fungal-acne-prone skin.
Yes. Niacinamide and peptides layer well with most actives. You can apply it after a vitamin C serum or before/after a retinoid. If you are using strong exfoliating acids (AHA/BHA) or retinoids, introduce everything gradually and consider alternating nights to avoid over-doing it on sensitive skin.
It is suitable for all skin types and is rated excellent for oily, combination, sensitive and acne-prone skin thanks to its lightweight, oil-free, fragrance-free formula. Dry skin will benefit too, but should layer a richer moisturizer on top to seal in hydration.
Most people notice softer, more hydrated and comfortable skin within the first 1โ2 weeks. A visible glow, calmer redness and more even tone are commonly reported around 3โ4 weeks, with barrier strength and fine-line softening building over 8โ12 weeks of consistent daily use.
It is designed for Step 4 of the K-Beauty routine โ the serum/treatment step. Apply it after cleansing, toner and any watery essence, and before your moisturizer. It can be used both morning and night; in the morning, always follow with sunscreen.
No. It is oil-free and clinically tested as non-comedogenic, earning a low comedogenic rating of around 1 out of 5. It is unlikely to clog pores or cause breakouts, which is why it is well suited to acne-prone and congestion-prone skin.
It has a Period After Opening (PAO) of around 12 months. To keep the probiotic ferments and peptides effective, store it closed in a cool, dry place away from direct sunlight and use it within that window after first opening.
Verdict: Yepoda The Repair Hero is a smart, gentle "barrier hero" that punches above its short ingredient list โ combining probiotic ferments, 2% niacinamide, copper peptides, hyaluronic and polyglutamic acid and vitamin B12 into a lightweight, fragrance-free serum that is vegan, cruelty-free, non-comedogenic and fungal-acne safe. It shines for sensitive, combination and acne-prone skin looking for hydration, calm and a natural glow, and the refillable glass packaging is a sustainability win. The main trade-offs are the conservative 2% niacinamide (less aggressive than 10% rivals for stubborn dark spots), a sometimes-fiddly pipette and a modest 30ml size for the price. If you want a daily, do-it-all serum that prioritizes skin barrier and comfort over high-strength actives, it earns its "hero" name.

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.
Note, that this does not include all ingredients part of the Silicone class of ingredients.
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 ยซpromisesยป 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 are Ingredients Related to Skin Type?
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
Pro Tip Alert!
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

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.
