Frequently asked questions
FAQTopical Tranexamic Acid is generally considered Category B (no evidence of risk in humans) and is minimally absorbed through the skin. However, there is limited research on topical use during pregnancy. We recommend consulting your healthcare provider before using this product during pregnancy or while breastfeeding. The serum is free of retinoids, salicylic acid, and hydroquinone which are typically avoided during pregnancy.
No, this serum is NOT fungal acne safe. It contains Polyglyceryl-10 Laurate, which may potentially feed malassezia yeast. If you're prone to fungal acne, consider alternatives like Cos De BAHA Tranexamic Acid Serum or Good Molecules Discoloration Correcting Serum, which have fungal acne-safe formulations.
Yes, Tranexamic Acid pairs well with most actives. It can be used with retinol (apply TXA first, then retinol), vitamin C (use in the same routine), and AHA/BHA (apply acids first, then TXA). However, if you're new to actives, introduce one at a time. For sensitive skin, alternate nights between this serum and strong exfoliants/retinoids rather than layering them.
This serum works best for oily and combination skin types due to its lightweight gel texture. It's also suitable for normal and dry skin (when followed by a moisturizer) and has been tested for sensitive skin. However, it's NOT recommended for those with fungal acne. Those with very reactive sensitive skin should patch test and introduce gradually.
Results vary by individual, but clinical studies show: immediate hydration and soothing, brighter complexion within 1-2 weeks, visible dark spot fading at 4 weeks (4.3% skin tone improvement, 29.59% reduction in inner pigmentation), and significant results at 8-12 weeks. Consistency is key - use twice daily with sunscreen for best results. Stubborn melasma may take longer.
Apply after cleansing, toning, and essence (if using), but before heavier serums, oils, moisturizer, and sunscreen. The routine order is: Cleanser → Toner → Essence → THIS SERUM → Other Serums → Moisturizer → Sunscreen (AM). Can be used both morning and night for maximum results.
This serum has a low comedogenic rating of 1/5 and is unlikely to clog pores for most users. It's oil-free, silicone-free, and has a lightweight gel texture that absorbs quickly. However, it does contain Polyglyceryl-10 Laurate which may trigger breakouts in those sensitive to fatty acid derivatives or prone to fungal acne.
The serum has a PAO (Period After Opening) of 12 months. The airless pump design helps maintain the stability and potency of active ingredients like Vitamin C by preventing air exposure. With twice-daily use of 2-3 pumps, the 30ml bottle typically lasts 4-6 weeks, well within the 12-month window.
Verdict: The Haruharu Wonder Centella 4% TXA Dark Spot Go Away Serum is a well-formulated, clinically-backed brightening serum that delivers on its promises. The combination of 4% Tranexamic Acid, 4% Niacinamide, Vitamin C, and soothing Centella complex makes it an effective multi-action treatment for dark spots and hyperpigmentation. The lightweight gel texture, fragrance-free formula, and airless pump packaging are thoughtful touches. While the small bottle size and non-fungal acne safe status are drawbacks, the efficacy and clean formulation make it a solid choice for those seeking to fade dark spots and achieve a more even skin tone. Best suited for oily to combination skin types who can commit to consistent use for 4-12 weeks.

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.

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.

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.
