Texture & feel
SENSORYHyaluronic Acid Hydration
Sodium Hyaluronate deeply hydrates and retains moisture while cleansing, so skin never feels tight or stripped after washing.
Soothing Botanical Extracts
Ginkgo Biloba Leaf Extract provides antioxidant protection while Licorice Root (Dipotassium Glycyrrhizate) calms redness and irritation.
Thermal Spring Water
Mineral-rich Thermal Spring Water from France helps strengthen the skin's natural barrier and protects against environmental irritants.
Ultra-Gentle Surfactants
Uses mild amino acid-based and amphoteric cleansing agents like Sodium Methyl Cocoyl Taurate that are gentle enough for baby products.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. All ingredients are considered safe for use during pregnancy and breastfeeding.
Contains Stearic Acid (C18 fatty acid) and PEG-14M which may potentially feed Malassezia yeast. However, as a rinse-off product with short skin contact time, the risk is minimal for most users.
Non-comedogenic formula. As a wash-off cleanser, ingredients have minimal time to clog pores. Stearic Acid (rated 2-3 in leave-on products) poses negligible risk when rinsed away.
pH-balanced at 5.0 with no fragrance, alcohol, or harsh surfactants. Multiple reviewers with rosacea report no irritation or stinging.
Contains MI, a preservative that can sensitize very reactive skin. It is considered acceptable in rinse-off products at low concentrations but is restricted in leave-on products in the EU.
Safe to use alongside retinol, vitamin C, AHAs, and BHAs. A gentle, non-active cleanser is ideal when using potent treatment products in your routine.

How to use
HOW TO USEWet Your Face
Splash your face with lukewarm water to dampen the skin and prepare it for cleansing.
Squeeze & Lather
Squeeze a small coin-sized amount onto your palm. Add a little water and work it into a gentle, creamy lather between your hands.
Massage Gently
Apply the lather to your face and massage using gentle circular motions for 30–60 seconds. Avoid harsh scrubbing — let the surfactants do the work.
Rinse Thoroughly
Rinse off with lukewarm water until no residue remains. Pat your face dry with a clean, soft towel — never rub.

Frequently asked questions
FAQYes. This face wash contains no retinoids, salicylic acid, hydroquinone, benzoyl peroxide, or chemical sunscreen filters — all ingredients commonly flagged during pregnancy. The formula uses only gentle surfactants, humectants (glycerin, hyaluronic acid), and soothing botanicals, making it safe for use during pregnancy and breastfeeding. As always, consult your doctor if you have specific concerns.
Use with caution. The formula contains Stearic Acid (a C18 fatty acid) and PEG-14M, which could theoretically feed Malassezia yeast. However, since this is a rinse-off product with very short skin contact time, the risk is considered minimal for most users. If you have active fungal acne, you may prefer a strictly FA-safe cleanser like Vanicream Gentle Facial Cleanser.
Absolutely. This is an ideal cleanser to pair with active treatments. It contains no actives itself, so there's zero risk of over-exfoliation or irritation from combining ingredients. A gentle, pH-balanced cleanser like this is actually recommended by dermatologists when using potent treatments like retinol or chemical exfoliants, as it allows the actives to work without additional stress on the skin barrier.
This cleanser is best suited for sensitive and normal skin types. It's also a good choice for dry and combination skin. Those with oily skin may find it too gentle and may prefer a foaming cleanser. It works exceptionally well for people with rosacea, eczema-adjacent sensitivity, or those recovering from over-exfoliation.
Most users notice immediate comfort — softer, calmer skin after the very first wash with no tightness or stinging. Within 1–2 weeks, you should see reduced redness and irritation. After 3–4 weeks of consistent use, expect improved skin texture and a healthier-looking complexion as your skin barrier recovers and strengthens.
Use it as Step 1 (or Step 2 if you double cleanse with an oil cleanser first). Apply it to damp skin, massage gently, and rinse. Follow with your toner, serum, moisturizer, and sunscreen (AM). For the Hada Labo routine, the brand recommends following with Hada Labo Hydrating Lotion (Light) as the next step.
No. With a comedogenic rating of 1/5, this cleanser poses very low pore-clogging risk. The only potentially comedogenic ingredient is Stearic Acid (rated 2-3 in leave-on products), but since this is a rinse-off product, it washes away before it can accumulate in pores. The formula is non-comedogenic for the vast majority of users.
The product has a Period After Opening (PAO) of 12 months. In terms of physical usage, the 100g tube typically lasts 4–6 weeks with twice-daily use (a small coin-sized amount per wash). Store in a cool, dry place and keep the cap closed to maximize shelf life and hygiene.
Verdict: The Hada Labo Mild & Sensitive Face Wash is a genuinely gentle, no-nonsense cleanser that lives up to its name. Its combination of Hyaluronic Acid, Thermal Spring Water, and soothing botanicals delivers a comfortable cleansing experience that respects even the most reactive skin barriers. At its affordable price point, it offers outstanding value — comparable in gentleness to premium European pharmacy cleansers at a fraction of the cost. The only notable drawbacks are the inclusion of Methylisothiazolinone (MI) preservative, which may concern those with extreme preservative sensitivities, and the small 100g tube size. If you have sensitive, normal, or dry skin and want a reliable daily cleanser that won't interfere with your active treatments, this is an excellent choice from Japan's #1 skincare brand.

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
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.
