Can you buy expensive skin care products for a small price? Are the "substitutes" of big brands really reliable?

Are the big-name skincare products that cost tens of thousands of yuan genuine or just "leek harvesters"? Can you really buy "cheap substitutes" with the same ingredients as big-name products with a small amount of money? How can you choose the skincare products that are right for you and do "effective skincare"...

In order to solve these problems that have been bothering everyone for a long time, Dad Review has brought out a new column "Ingredients": putting aside the exaggerated propaganda, we will take you to understand the real efficacy of the product from the ingredients.

In the first issue online, let’s talk about the core ingredient that has made “Ya S Lan D Little Brown Bottle” always at the top of the best-selling list and popular for 40 years: bifida yeast.

Although the word "yeast" is in its name, bifid yeast is actually cultivated from bifidobacteria. In the "Catalogue of Used Cosmetic Raw Materials (2015 Edition)", there are three ingredients for "bifid yeast":

The one that is actually used in the Ya S Lan D Little Brown Bottle is the second one, namely the lysate of bifid yeast fermentation product.

It is the metabolites and cell fluid clear fluid obtained by culturing, inactivating, breaking the cell wall and centrifuging Bifidobacterium (Bifidobacterium), including cytoplasmic fragments, cell wall components and polysaccharide complexes, and is rich in protein, yeast polypeptides, yeast polysaccharides and other trace elements.

In simple terms, the lysate of bifidobacterium fermentation product is the "corpse and body fluid" of the crushed bifidobacterium, which is an intracellular substance. It has the function of preventing photoaging caused by ultraviolet rays and promoting DNA repair.

The core ingredient of this product is "Bifida Saccharomyces cerevisiae fermentation product lysate"

The filtrate and extract of bifidobacterium fermentation products may be by-products of the fermentation process of bifidobacteria, or they may just be the "bath water" of bifidobacteria. Their main effect is moisturizing.

Here are the key points for you:

Are you usually an impulsive spender or a rational spender who does his homework? Recently, our editor found a "small brown bottle substitute" product on a certain platform:

For less than 1/4 of the price, you can get a product with a higher amount of bifid yeast than the little brown bottle. Isn't this a definite substitute for big brands?

Stop! Let's analyze it first: the bifid yeast added to the skin care products of Yaslan D and Olay Group is from the German raw material supplier CLR, and its efficacy has been verified by in vivo experiments on volunteers and indirect in vivo experiments.

The bifid yeast added to this product ranks first in the ingredient list, so the content should be at least greater than 70%. If the same raw materials are used, the cost of bifid yeast alone is close to the selling price (123.51 yuan/50mL)!

Although they are all called bifid yeast, different suppliers have different strain screening, fermentation process, cell wall breaking process, etc., and the ingredients and efficacy of the products are naturally not comparable.

Therefore, even if the "same" ingredients are added, it cannot be called a "substitute" product.

There are also some products whose details pages say "Bifida yeast repair essence without a drop of water" and "high-concentration compound yeast essence", but when you check the ingredient list, they are all "Bifida yeast fermentation product filtrate"...

What is the filtrate? What is the effect of "water"? "Moisturizing"

Therefore, at least in the field of skin care products, it is unlikely to buy the same products as big brands or even better value products at super low prices. We should look at it rationally.

Rather than blindly following trends, the most important thing is to understand your skin type and choose products that suit you.

Finally, we would also like to remind everyone that when choosing some functional products, you should carefully check the ingredient list to see if there are corresponding ingredients, and not just listen to the merchant’s propaganda.

We have also summarized a "Comparison Table of Effective Ingredients and Products" for everyone, long press to save and collect——

I hope everyone can become a "wise" consumer and avoid pitfalls when shopping! What other "hot ingredients" do you want to know about? Leave a message now!
