MINON AminoMoist Masks in Japan: Which of the Four Should You Choose?

I'm Irene, a Japanese-licensed pharmacist working in a Japanese drugstore. I was born in Taiwan and moved to Japan at around age 10. MINON's four-sheet boxes look similar, so let's start with what you want from the mask: extra moisture, a lighter finish, a richer feel or a specific medicated claim.

Choose by your main concern

For a straightforward moisturising mask, start with the pink Purupuru box. If dryness comes with an oily T-zone, look at the green combination-skin mask. The blue milk mask is the only Japanese quasi-drug in this comparison; the deeper pink aging-care mask offers a richer serum and a longer sheet.

The mL figures describe the serum in each sachet, not a strength ranking. All four are face sheet masks used for about 10–15 minutes after toner.

Recognise the four boxes

Pink: Purupuru Moist Skin Mask, FMb

The Japanese name is ぷるぷるしっとり肌マスク. Its gel serum contains moisturising ingredients including butylene glycol (BG), glycerin and amino acids. Choose this when your priority is a hydrated, soft finish without specifically seeking a medicated whitening product.

The maker has evaluated its claim to make fine lines caused by dryness less noticeable. Keep that qualifier: it does not promise to erase deeper wrinkles or treat a skin condition.

Blue: Medicated Whitening Milk Mask, WFMa

Look for 薬用うるうる美白ミルクマスク and 医薬部外品, the Japanese quasi-drug category. The two active ingredients are ascorbic acid 2-glucoside, a vitamin C derivative, and dipotassium glycyrrhizate. The milk-serum formula is labelled for preventing spots and freckles through suppression of melanin formation, and for preventing skin roughness.

Here, the Japanese word bihaku, often translated as “whitening,” has that specific preventive meaning. It does not mean bleaching your natural skin colour or removing existing pigmentation. The mask also does not replace sunscreen. Despite the brand's after-sun-related wording, the actual precautions say to wait until sunburn redness and heat have settled before use.

Green: Smooth and Moisturizing Skin Mask, BF

The Japanese name is すべすべしっとり肌マスク. This version is aimed at combination skin: areas that feel dry alongside areas that become oily. Its gel serum has a less-sticky finish and includes moisturising amino acids plus the skin-conditioning amino acid aspartic acid.

The sheet is shaped to cover around the sides of the nose and chin. Fit those sections gently; if a small cheek gap remains, the maker advises drawing the sheet in from the sides.

BF is a cosmetic, even though the brand discusses blemish-prone skin. Non-comedogenic testing does not make it an acne treatment or guarantee that no one will develop blemishes.

Deep pink: Soft and Fluffy Skin Mask, AF

Look for もちもちふっくら艶肌マスク. This mask has a rich, viscous serum and a longer sheet that reaches below the chin. Its ingredients include glycerin, amino acids and acetyl hexapeptide-38, the peptide highlighted by the brand.

Choose it for its moisturising feel and coverage if those are what you enjoy. “Aging care” means care suited to your age; a peptide name or a chin-covering sheet does not establish a lifting treatment or reversal of skin aging.

Irene's shelf tip: the moisturising and whitening milk masks were renewed in August 2025. The current Japanese sales names are FMb and WFMa. Older overseas pages may still show FMa or WFM, so match the Japanese box and back label when replacing a product you already own.

How to use them comfortably

1. After cleansing and applying toner, open one sachet. Unfold the sheet vertically, then sideways. Use it immediately after opening.
2. Align the eye openings, then the forehead and mouth, and gently fit the sheet over your face. Keep serum out of your eyes. For AF, fit the longer lower section beneath the chin.
3. Remove after about 10–15 minutes. There is no need to exceed 15 minutes even if the sheet still feels wet. Do not sleep with it on.
4. Gently press the remaining serum into your skin with your palms. Add moisturiser or cream if needed. Discard the sheet after one use; do not save it for tomorrow or flush it down a drain.

The maker suggests once or twice a week as a guide. It allows daily use depending on skin condition, but daily masking is optional. More frequent or longer wear is not a reason to continue through stinging or redness.

Sensitive-skin care still needs precautions

• Avoid damaged areas: do not apply over wounds, swelling, eczema or other abnormal skin. After sunburn, wait for redness and heat to subside.
• Stop and consult a dermatologist if redness, swelling, itching, irritation, loss of pigment or darkening appears during use, or if similar changes develop when treated skin is exposed to sunlight.
• Eye contact: rinse immediately if serum enters the eyes.
• Ingredient allergies: check the exact pack if you have a known cosmetic-ingredient allergy. BF lists kiwi extract; WFMa lists hydrogenated soybean phospholipids. These are cosmetic ingredient examples, not a food-allergen declaration or proof that a food allergy will cause a skin reaction.
• Tests are not guarantees: BF and AF list allergy, patch and stinging tests, with an explicit warning that reactions can still occur. BF's non-comedogenic test also does not guarantee freedom from blemishes.
• Storage: keep out of children's reach, away from direct sunlight and extreme heat or cold. Do not freeze the masks; the BF and WFMa labels specifically warn against freezer storage.

These face masks are not a treatment for eczema or persistent facial inflammation. If that is why you are shopping, have the skin problem assessed rather than trying several masks in succession.

Three questions before adding a box to your basket

Does a blue “whitening” box work like a sunscreen?

No. Its spot-prevention claim concerns melanin formation. Continue your usual sun protection; do not use the mask on hot, red, freshly sunburned skin.

Is the aging-care mask automatically better than the ordinary pink one?

Choose by feel and coverage. AF has a richer serum and longer sheet; FMb already has a specific evaluated claim for the appearance of dryness lines. The names do not create a universal ranking.

Which detail matters most when buying a replacement?

Match the full Japanese name and sales-name suffix, then check the ingredient list on your own pack. For a first purchase, choose one that fits your main concern and use it for the stated time. Comfortable skin matters more than finishing a four-sheet box quickly.
