You can use the lotion before or after you apply Topical Steroids depending on your preference. Either way it does not affect the effectiveness of the lotion.


Are the additives in Dr. Fukaya's Skin Repair Lotion safe? Are they toxic?

The additives we use in our lotion are for preservation purposes and are commonly used ingredients that we believe they are safe.
However, we understand that there may be a slight chance of allergy or contact dermatitis. For such cases, we have Dr. Fukaya's Skin Repair Lotion without any preservatives. However, those lotions without preservatives are more likely to be contaminated with mold or bacteria soon after use. Therefore, we do not currently offer these lotions unless you are diagnosed with allergy or contact dermatitis by your doctor. We also have a test reagent for the 3 types of additives used in our lotion available if your doctor agrees to provide you with a patch test.

You can see some information of the additives in our lotion here:
Phenoxyethanol
Iodopropynyl Butylcarbamate
Hydroxypropyl-b-Cyclodextrin


I'm using coal tar solution to control itch. Can I replace it with Dr. Fukaya's Skin Repair Lotion?

Coal tar and hyaluronic acid are too different to replace with each other. We recommend to continue using coal tar solution in addition to Dr. Fukaya's Skin Repair Lotion.


I was just reading over the Barnes report and noticed that it stated the molecular weight of HAFI is 50,000 - 400,000da. However, I noticed your repair lotion is 50,000 - 110,000da. How can you be sure that HA fragments that are 110,000 - 400,000da are not important in reversal of skin atrophy?

There are two reasons why our Dr. Fukaya Skin Repair Lotion(50000 - 110,000da) is effective.

1. The hyaluronan receptor for endocytosis (HARE) activates NF-κB-mediated gene expression in response to 40-400k da, but not smaller or larger hyaluronans.

The Fig5 in the following link shows that the activation is most strongly observed around 100,000da.

2. You can find the result of electrophoresis of our lotion's ingredient (hyaluronan of 50,000 - 110,000da) in the second image, No.7 in the following link (Dr. Fukaya's Japanese blog). As it shows, the peak is 50,000 - 110,000da, but it also covers the wider range of molecular weight of HAFI.

From those two reasons, we are convinced that our lotion is effective.

In the first place, Dr. Barnes divided the molecular weight into the three ranges based on the following paper (the link below), and the number itself (50,000 - 400,000da) does not have any practical meaning. Dr. Barnes proved that there are some molecular weights which serve as the activator within the range of 50,000 - 400,000da.

Can I use Dr. Fukaya's Skin Repair Lotion on any part of body and face?

Yes, Dr. Fukaya's Skin Repair Lotion can be used on any part of body and face, including scalp and genital area.


Can the summer heat affect Dr. Fukaya's Skin Repair Lotion?

No, hyaluronic acid is highly tolerant of heat and light. In fact, our lotion is heated to 130 °C for sterilization in the production process. Therefore, it is impossible that the lotion is degraded by the summer temperature.


Where can I find the expiry date?

Hyaluronic Acid is chemically stable and resistant to heat and light. Dr. Fukaya's Skin Repair Lotion uses a single component and the ingredients don't change its component. So, we don't set its lifetime as you can use it safely for very long time.


How long does it take to see the results?

The effects of the lotion can vary on each customer. We normally recommend to use it twice a day for 3 months. You may be interested to read the reviews from our customers (http://drfukaya.ocnk.net/page/11).


I have heard that similar products can have harmful ingredients. Can you confirm that this is not the case with your product.

Our lotion is safe and it work gently. If you are allergic to any of the preservatives, we have a non-additive version available.


I think that my skin is reacting to the lotion. What should I do?

If you are currently going through topical steroids withdrawal, your skin can react to the lotion at the early stage of withdrawal. This is because skin can be hyper sensitive during this period and can react to anything, even to water. In such a case, we recommend to stop the use of the lotion for a while and try again later.


Does your lotion help with surgery scarring and atrophy, indented scarring?

Our Skin Repair Lotion is effective to reduce itchiness and dryness of scars, but we are afraid that it does not improve scars themselves.


Can I buy your products locally?

We currently have one distributor in the UK. Please be advised that our distributors have their own policy on price, delivery and conditions. We also deliver our products to the UK from Japan from our website.
