New Product Development Journal 20250220 WCS + Silver Fox

Dear friends, hello everyone!

Today, I tested two types of blended brushes. One is WCS mixed with high-grade Saikoho, and the other is a brand-new concept we are experimenting with—WCS mixed with silver fox.

The functionality and superiority of WCS mixed with Saikoho are, I believe, already well recognized. However, this blend still has some drawbacks, such as:
1. Since it contains Saikoho, friends with sensitive skin may occasionally find the texture less comfortable.
2. Saikoho performs moderately with all powder products. With matte powder foundations, it can appear flat and lacking dimension, while with pearlescent formulas, it may sometimes look a bit abrupt. Although WCS helps mitigate these issues to some extent, limitations still exist.

Saikoho is an excellent blending material due to its superior elasticity. However, in terms of hair structure, it is quite similar to WCS—both have fine, tapered tips and thick bases. (WCS has an even more extreme ratio of tip-to-base thickness, which is why I avoid using WCS for flame-shaped brushes, as the brush head would feel weak and lack control.)

When two similar hair types are blended, they apply products effectively—just like how the WCS + Saikoho flat-top brush performed with Suqqu’s newly released soft-focus powder foundation in my video. It instantly created a beautifully diffused effect, which was impressive at first, but upon closer inspection, I felt slightly dissatisfied.

After reflecting on it, I realized that this dissatisfaction might stem from excessive soft focus. It seemed to blur everything too much, smoothing out all texture—even bone structure—making the complexion look overly flat, almost like a blank sheet of paper.

I think this might be the downside of WCS + Saikoho. The tapered tips of both hairs pick up a large amount of product, and when applied, they release everything at once.

So, I tried WCS + silver fox on the other half of my face. This time, I achieved a soft-focus + radiant finish. My skin looked refined, my pores appeared smaller, but it still had dimension and didn’t feel lifeless.

I believe this is the key advantage of WCS + silver fox. Structurally, silver fox hair is the complete opposite of WCS—it has a rounded tip and a fine base. When combined, the two hairs interlock like puzzle pieces, forming a tightly integrated, velvety surface.

Think about it—why do we use soft velvet cloths to polish silverware and leather goods? Isn’t it because the smooth, rounded sheen enhances their luxurious appearance?
