Local organic skin care products

Imported products would have to be expensive, that's a given. 

Anything made in Vietnam would not be certified as natural or organics because there isn't an agency to inspect the products and hand out the certification.

I haven't knowingly or voluntarily put any synthetic product on my skin for almost two decades now.  What I currently use, I brought with me from the US.   

I only have advice for one item on your list: shampoo.  Use baking soda and apple cider vinegar.  Tens of thousand Americans have been using the method for decades.  I did for almost 5 years, until it became too much of a hassle in our frequent travel.  I switched to Dr. Bronner's after that.

My soap and shower gel are either from Dr. Bronner or natural and organic handmade products from a small farm in Ohio, US.  They last forever.

I blend essential oils from my own stash to use as face, hand, and body moisturiser/cleanser (also for mosquito repellent and after bites, cold, fever, sinus, stomach problems, muscle ache, hair conditioner, sleep aid, headache, sunburn, energising, etc. ).  I brought my essential oils from the States but you can buy them in Hanoi or Saigon and design a solution for your needs.

As for your idea of affordable, I seriously doubt you can find a full size (75-100 ml) or extra large size (200 ml) of any natural product for 100K or the equivalent value, even if you order directly from the company's website.  Natural and/or organic products are more expensive to produce than synthetic ones.

Thank you for the suggestions Ciambella.

But blending products is too much effort for me.

In Europe you can really buy these products for about 100k.
The price different between organic and other products is not so big in Europe than here in Vietnam.

If I not can find suitable local products here, I must find an online shop which delivers from Europe to Vietnam.

Actually the best thing is to look for Korean products. Not ALL are as you require but many are.

The mall near the Old Post Office has loads. I got some great shampoo and the best toothpaste plus an electric toothbrush that zips.

What I cannot find is underarm deodorant without all the cancer inducing ugliness. 

I am rapidly down to a sliver of my crystal which works wonders ... And I'm a guy.

Anyone know where to find crystal deoderant? Dont even try to ask at beauty shops. No idea what I am talking about.
