Medicated Emulsion
Product Description
Product overview
A medicated milky emulsion from Shiseido's IHADA line, formulated with ultra-pure petrolatum and two anti-inflammatory actives (allantoin & dipotassium glycyrrhizate) to calm, protect, and deeply moisturize sensitive, dry, and irritation-prone skin. Lightweight yet surprisingly rich, it absorbs quickly with zero stickiness.
Ultra-Pure Petrolatum Barrier
Shiseido's proprietary high-purity petrolatum seals in moisture and shields the skin barrier from external irritants like dryness and pollution.
Texture & feel
SENSORYUltra-Pure Petrolatum Barrier
Shiseido's proprietary high-purity petrolatum seals in moisture and shields the skin barrier from external irritants like dryness and pollution.
Dual Anti-Inflammatory Actives
Allantoin and dipotassium glycyrrhizate work together to soothe redness, calm irritation, and prevent recurring roughness and inflammation.
Aqua Synergy Hydration
A mineral-rich blend of sodium glutamate, sodium PCA, calcium chloride, and magnesium chloride that delivers deep hydration to the stratum corneum.
Lamellar Lipid Technology
Phytosteryl/octyldodecyl lauroyl glutamate mimics the skin's natural lipid bilayer structure, reinforcing the moisture barrier from within.
Safety & compatibility
SAFENo retinoids, salicylic acid, hydroquinone, or chemical sunscreens. All ingredients are considered safe for use during pregnancy and breastfeeding.
Contains PEG-20 glyceryl isostearate and pentaerythrityl tetraethylhexanoate (esters) that may feed malassezia yeast. Not ideal for active fungal acne flare-ups.
Petrolatum is non-comedogenic despite its occlusive nature. The lightweight emulsion formula is unlikely to clog pores for most skin types.
Free from parabens, alcohol, fragrance, and colorants. Weakly acidic pH. Allergy tested and designed for daily use on sensitive, reactive skin.
This gentle emulsion layers well with active serums including retinol, vitamin C, AHA, and BHA. Apply after actives as a protective moisturizing step.
Classified as 医薬部外品 (quasi-drug) in Japan, meaning it contains government-approved active ingredients at regulated concentrations for specific skin benefits.
Ingredient breakdown
INGREDIENTSAllantoin ActiveProven
A well-researched soothing and skin-conditioning agent derived from the comfrey plant (produced synthetically for purity). Calms irritation, promotes cell turnover, and supports wound healing.
- Function: Anti-inflammatory, skin protectant, keratolytic agent that promotes healthy cell renewal
- Research: Clinical studies show allantoin accelerates wound healing and reduces skin irritation at concentrations of 0.5-2%
- Benefit: Soothes rough patches, itchiness, and redness while softening the skin surface
Dipotassium Glycyrrhizate ActiveProven
A potent anti-inflammatory compound derived from licorice root (Glycyrrhiza glabra). Widely used in Japanese medicated skincare for its ability to calm redness, soothe irritation, and provide antimicrobial benefits.
- Function: Anti-inflammatory, antimicrobial, and mild skin-brightening properties
- Research: Glycyrrhizin compounds demonstrated anti-inflammatory activity comparable to hydrocortisone in clinical settings
- Benefit: Reduces visible redness, prevents recurring inflammation, and supports a calmer complexion
Highly Purified Petrolatum Barrier AgentProven
Shiseido's proprietary ultra-pure grade petrolatum, refined using advanced technology to remove impurities. The gold-standard occlusive that prevents transepidermal water loss (TEWL) more effectively than any other ingredient.
- Function: Occlusive moisture barrier that reduces TEWL by up to 98%
- Research: Petrolatum is the most effective occlusive agent known in dermatology, endorsed by dermatologists worldwide for eczema and compromised skin barriers
- Benefit: Locks in hydration, protects from environmental stressors, and supports barrier repair
Aqua Synergy Complex Moisturizing BlendPromising
IHADA's signature hydrating complex combining sodium glutamate, sodium PCA, calcium chloride, and magnesium chloride. These minerals and amino acid derivatives mirror the skin's natural moisturizing factor (NMF) to deliver deep, lasting hydration.
- Sodium PCA: A component of the skin's NMF; highly hygroscopic humectant that attracts and retains water
- Sodium Glutamate: Amino acid-based moisturizer that conditions and softens the stratum corneum
- Mineral Salts: Calcium and magnesium chloride support skin barrier integrity and cellular function
Phytosteryl/Octyldodecyl Lauroyl Glutamate EmollientPromising
An amino acid-derived lipid that forms lamellar liquid crystals similar to the natural lipid bilayers found between skin cells. Reinforces the skin barrier at a structural level.
- Function: Biomimetic emollient that integrates with the skin's intercellular lipid matrix
- Benefit: Strengthens and repairs compromised skin barriers; helps maintain long-lasting hydration

Where it fits in your routine
ROUTINEApply after toner/lotion and serums. In the Japanese skincare routine, emulsions come after lotion (toner) to seal in hydration. Can be used as a final step for oily skin, or followed by a cream/balm for extra-dry skin.
How to use
HOW TO USECleanse & Tone
Start with a clean face. Apply your toner or lotion (such as IHADA Medicated Lotion) to damp skin and let it absorb.
Dispense the Emulsion
Take an appropriate amount (about a 10-yen coin size, or roughly a nickel) into the palm of your hand.
Gently Spread Over Face
Using your fingertips, gently spread the emulsion over your entire face. Focus on areas prone to dryness, redness, or irritation such as cheeks and around the nose.
Pat to Absorb
Lightly pat the product into the skin until fully absorbed. No rubbing needed — the fluid texture melts in on its own within seconds.
Follow Up (Optional)
For very dry or compromised skin, follow with IHADA Medicated Balm or a heavier cream to lock everything in. In the morning, finish with sunscreen.
Who is it for?
WHOPerfect for you if:
- You have sensitive, easily irritated, or reactive skin
- Your skin gets dry, rough, or flaky — especially in cold or dry weather
- You want a lightweight moisturizer that doesn't feel heavy or greasy
- You prefer a minimal, additive-free formula without fragrance or parabens
- You need a calming emulsion to pair with active treatments (retinol, AHA/BHA)
- You have eczema-prone or compromised skin barrier
- You're pregnant or breastfeeding and need a safe daily moisturizer
Consider alternatives if:
- You have active fungal acne (contains esters that may feed malassezia)
- You want anti-aging or brightening benefits (no retinol, niacinamide, or vitamin C)
- You prefer a very rich, heavy cream texture for extremely dry climates
- You want a completely silicone-free formula (contains decamethyltetrasiloxane)
- You need a standalone moisturizer for very oily skin in hot, humid weather
Skin type compatibility
SKIN TYPESSpecifically designed for sensitive skin. Fragrance-free, hypoallergenic, allergy-tested with anti-inflammatory actives that actively calm reactive skin.
Ultra-pure petrolatum creates a powerful moisture seal. Glycerin and Aqua Synergy complex deliver deep hydration. Follow with a balm for severely dry skin.
Lightweight enough not to overwhelm oily zones, while providing sufficient moisture for dry areas. May feel slightly rich for very oily T-zones in summer.
The petrolatum base may feel too occlusive for very oily skin in humid climates. Best used in cooler months or as an evening-only moisturizer for oily types.
Low comedogenic rating (1/5) and anti-inflammatory actives help calm acne-related redness. However, those with fungal acne should patch test first due to ester content.

Budget-friendly alternatives (dupes)
DUPESCeramide-based approach instead of petrolatum. Slightly lighter texture with pseudo-ceramide technology. Also fragrance-free and designed for sensitive skin, but focuses on ceramide barrier repair rather than anti-inflammatory actives.
Uses 9 amino acids instead of petrolatum for moisturization. Richer, creamier texture. Also hypoallergenic and fragrance-free, but lacks the medicated anti-inflammatory actives that IHADA provides.
Soy-derived ceramide formula with 5 types of ceramides and hyaluronic acid. More focused on barrier support than soothing. Lighter texture but without the medicated quasi-drug classification or anti-inflammatory actives.
Another Shiseido sub-brand. Medicated emulsion with plant extracts for sensitive skin. Slightly more elegant texture but pricier. Also a quasi-drug with anti-inflammatory benefits, targeting similar concerns.

Frequently asked questions
FAQYes. IHADA Medicated Emulsion does not contain any ingredients known to be harmful during pregnancy or breastfeeding. There are no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or other restricted ingredients. The two active ingredients (allantoin and dipotassium glycyrrhizate) are considered safe for topical use during pregnancy. However, as always, consult your healthcare provider if you have specific concerns.
Use with caution. The formula contains PEG-20 glyceryl isostearate and pentaerythrityl tetraethylhexanoate, which are esters that may potentially feed malassezia yeast. While petrolatum itself is fungal acne safe, these additional ingredients mean this product may not be the best choice during an active fungal acne flare-up. If you're prone to fungal acne, consider patch testing first or consulting a dermatologist.
Yes. IHADA Medicated Emulsion is an excellent companion to active treatments. Its soothing, anti-inflammatory formula can help buffer the irritation sometimes caused by retinol, vitamin C, AHA, and BHA. Apply your actives first, allow them to absorb, then follow with this emulsion to calm and protect the skin. Many users find it helps reduce the dryness and flaking associated with retinol use.
This emulsion is specifically designed for sensitive and dry skin types. It excels for those with easily irritated, reactive, or eczema-prone skin. It also works well for combination skin. Those with very oily skin may find it slightly rich for daytime use in hot weather, though it makes a great nighttime moisturizer for all skin types. The lightweight fluid texture makes it more versatile than a typical cream.
Most users notice immediate comfort and soothing on the first application. Visible improvement in rough, flaky patches typically occurs within 1-2 weeks of consistent use. Reduced redness and a calmer complexion generally become apparent after 3-4 weeks. Full barrier repair and improved skin resilience may take 2-3 months of regular use.
In the Japanese skincare routine, apply this emulsion after your cleanser, toner (lotion), and any serums or treatment essences. It serves as a milky moisturizer that seals in the hydration from previous steps. For very dry skin, you can follow it with a heavier cream or balm (like the IHADA Medicated Balm). In the morning, always finish with sunscreen.
IHADA Medicated Emulsion has a low comedogenic rating of 1 out of 5. While it contains petrolatum (which is non-comedogenic), the overall formula is designed to be light and non-pore-clogging. It is allergy-tested and formulated to be less likely to cause acne, though individual reactions can vary. The product carries a Japanese certification indicating it has been tested for acne formation risk.
The recommended period after opening (PAO) is 12 months. Store in a cool, dry place away from direct sunlight and high temperatures. Always wipe the container mouth clean after each use and close the cap securely. With twice-daily use (AM and PM), a 135ml bottle typically lasts about 2-3 months.
Verdict: IHADA Medicated Emulsion is an outstanding everyday moisturizer for anyone with sensitive, dry, or reactive skin. Its brilliance lies in the simplicity — a clean, minimal formula with two proven anti-inflammatory actives backed by Shiseido's proprietary ultra-pure petrolatum technology. The fluid, milky texture feels deceptively light but delivers surprising depth of hydration and barrier protection. It's one of those rare products that works quietly and reliably, without flashy ingredients or marketing hype. A true J-beauty staple that earns its "Best Pick" status among Japanese skincare reviewers. The only reason it doesn't get a perfect 5/5 is the ester content that makes it unsuitable for fungal acne sufferers, and the lack of active anti-aging ingredients. For what it sets out to do — soothe, protect, and hydrate sensitive skin — it does it exceptionally well.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
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.
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
Notable Effects & Ingredients
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.
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!
Ingredients Related to Skin Types
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.
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.
