Completely fading dark spot is quite difficult to get, but you can see the results like even skin color and % fading dark spot
try alpha-arbutin + ethyl ascorbic acid -
Another is usually stirring glycolic with NaOH
i tried to dilute glycolic but the pH is changing little. -
@MarkBroussard, thanks.
there Is problem with glycolic acid that for maximum effect of glycolic acid, the pH must be around 3.8 and fda allows < 10% concentration and its side effect on exposing to sun light or hot temperatures. -
@tinj, where do you buy it?
its color is not correct. -
After research, I found that
when applying cream to the skin, there are three possible ways:
1) if the ingredients < 500 daltons , they are absorbed through skin.
2) if the ingredients > 500 daltons, they may be absorbed through the glance
3) if the ingredients > 500 daltons, they may be absorbed between the cells
most of extra oils will be staying on the surface of the skin to perform occlusive.
it takes about 30 minutes for absorption -
@ngarayeva001, do you know any tools to measure? I just do by vision
-
Molecular weight of ethyl ascorbic acid is 204 da
So both of them have molecular weight less than 500 da -
Molecular weight of alpha arbutin is around 272 g/mol = 272 da
-
Just vision check on the picture before applying the cream and after 4 days (taking pictures)
next times checking is 8th day. -
Here after 4 days, apply cream before going to bed.
cream with only alpha arbutin: nothing improved
cream with alpha arbutin + ethyl ascorbic acid: skin tone brighten and more even + fading dark spots about 20%. -
@ngarayeva001, questions:
so what happens when cream was applied to the skin?
The emulsifiers combine the water and oils . The water and oils may contain the active ingredients. I read 500 dalton rules.
Thanks -
@MarkBroussard thanks a lot.

@ngarayeva001, thanks
can you explain the penetrating processes of cream to skin? -
@MarkBroussard, what are differences between vitamin E and
tocopherol acetates? -
@Pharma, @ngarayeva001 thank you so much.
I will have the results: alpha-arbutin vs. alpha-arbutin + ethyl ascorbic acid soon. I will let you know.@Pharma, I have a lot of basic questions. Would you please help me? You have great knowledge and sharing. I again appreciate you a lot.
our skin doesn’t absorb water? Only oils with small molecular weight can be absorbed through our skin? Because Most active ingredients are water soluble, therefore we need to choose oils(easy absorbed) and emulsifiers with small molecular weight => cream is easy to absorb to our skin? -
@Pharma, I have question: the modified ascorbic acid such as ethyl ascorbic acidenter the cell. After enzyme, ascorbic acid is off to protect the cell. Where does ethyl go?
thank you in advance. -
@Perry thanks a lot.
-
@ngarayeva001, thanks. I am clear now
-
@Perry, thanks for answer.
I read the article on Total Beauty. There are combo therapies to remove the dark spots (hyper pigmentation):
1) licorice root extract +
glycolic acid + vitamin E ,"y":1064,"w":20,"h":18,"abs_x":384,"abs_y":2384}”>
2) licorice root extract +
vitamin C + niacinamide
3) ,"y":1083,"w":397,"h":56,"abs_x":384,"abs_y":2403}”>kojic acid + arbutin +
green tea extract + vitamin C

For narrow topics I like to discuss:
1) uneven skin tone and dark spots
2) firming, sagging and wrinkles -
@ngarayeva001 thanks

Thanks
-
@ngarayeva001 what does LAA mean? I don’t understand it. Would you explain.

Typo metal instead of alkaline
