The efficacy of SK-II Facial Treatment Essence. You must buy the limited edition SK-II Facial Treatment Essence just for its packaging.

Recently, I was really amazed by the limited edition packaging of SK-II Facial Treatment Essence! It actually came out with 3 limited edition white bottle packaging, each with colorful English declaration graffiti of "change", "destiny" and "decision".

The efficacy of magic water

Although limited editions have been released before, this is the first time in 37 years that SK-II has used a non-transparent bottle for the magic water. The shape is very trendy~

Now I won't confuse it with Clear Dew. When I was young and ignorant, I thought that the Fairy Water was just lotion. But when I bought it and did some research, I found that there was also a product called Clear Skin Rejuvenating Lotion. The bottle looked very similar to the Fairy Water. I was a little confused. What was the difference between the two?

In fact, the function of Clear Lotion is equivalent to that of lotion, while Fairy Water is the essence! Thinking of this, I feel it is necessary to remind everyone again what kind of product can be called essence!

People often regard "essence" as a product in a fixed form. There was a time when I was always confused when looking at various essence waters, essence liquids, and essence milks. I was particularly concerned about whether they were essences or milks!

Water or milk, it all depends on the texture

First of all, let’s clarify a concept: water, lotion, cream, and oil are the texture classifications of skin care products.

In the hands of formulators, the same few active ingredients can be made into water, lotion, and cream respectively. The only difference may be that one has more water and a lighter texture, while the other has more oil and a thicker texture. You can choose the texture that suits you according to your skin type and seasonal changes.

Depending on different needs and ingredient characteristics, the essence can be made into any of these forms.

The essence is the quantity

I think the so-called essence must meet the following conditions: it must contain one or more active ingredients with a high concentration, or sufficient amount, to solve a certain type of skin problem.

For example, anti-wrinkle essence mainly contains a series of antioxidant ingredients such as grape seed, whitening and freckle removal essence mainly contains vitamin C and niacinamide, essence for removing blackheads or closed comedones mainly contains salicylic acid, and moisturizing essence mainly contains yeast extract, hyaluronic acid, etc.

An all-purpose essence may use a single all-purpose ingredient, or may use multiple ingredients with different functions to work synergistically to achieve the effect.

These ingredients are at the front of the ingredient list, and the amount added is much larger than other skin care products. Of course, the price is correspondingly higher. The function of toner is only secondary cleansing, softening the skin and replenishing moisture, and it does not need to contain too many active ingredients.

The SK-II Facial Treatment Essence mentioned at the beginning, also known as the Fairy Water, has 7 ingredients, of which there is 1 core active ingredient - PITERA?, with a content of up to 90.7%. It is very effective in moisturizing, inhibiting free radicals and promoting keratin renewal metabolism, so it can be said to be a water-like essence.

What is the active ingredient PITERA?

SK-II’s signature ingredient, PITERA?, is named “Galactosaccharomyces fermentation filtrate” on the ingredient list.

Note that it is not the yeast itself, but the filtrate extracted from the yeast during the fermentation process. This ingredient cannot be synthesized artificially at present. Also, anyone who dares to say that they added "live yeast" must not know what microbial testing is. It is definitely exceeding the standard, so it should be sent back for re-production!

Yeast, as a single-cell fungus, contains a large number of ingredients needed by the human body, such as amino acids, proteins, minerals, vitamins, and carbohydrates, and naturally contains a lot of metabolic products.
