Brand Overview

Biore’s Anti-Blemish In-Shower Flash Treatment isn’t a terrible product, per se… but because it can’t really do what it claims, it’s one to leave on the shelf.

This blue gel-cream comes in a squeeze tube, and its main hook is that it warms on contact. It does indeed “heat up” briefly (it actually gets quite hot, whereas products with a similar concept that we’ve tried aren’t quite as intense) thanks to a chemical reaction whose transient nature is relatively harmless on skin. Some might find the sensory experience pleasant, but the flash of warmth has no impact on acne or blemishes, and certainly can’t melt acne away as claimed; if anything, overuse of a product that gets this hot could lead to signs of sensitivity, especially if you struggle with issues like rosacea.

The active ingredient in this cream is 2% salicylic acid, the gold standard when it comes to exfoliating deep inside pores to treat and prevent acne. Unfortunately here it can’t work as potently as claimed, and the reason is twofold. First, it’s formulated at a pH of 5.80, well above what’s considered optimal (between pH 3 and 4) for exfoliation to occur. Second, this is a product that’s rinsed off immediately, and salicylic acid is most effective in leave-on formulas.

Though Biore doesn’t mention it in its claims, this contains cellulose microbeads to provide manual exfoliation. Thankfully, the beads are small and round enough that they aren’t abrasive. This also does a pretty good job removing oil from skin thanks to the high amount of zeolite clay it contains, as well as the surfactant sodium lauroyl lactylate.

Aside from those aspects, though, there just isn’t much to write home about here, especially considering this contains fragrance, which puts skin at risk for irritation.

Although this is rinsed from skin, the potential for irritation remains. Skip this, and instead selection a product that will have a meaningful impact on acne from our list of best acne and blemish treatments.

  • Cellulose microbeads provide gentle manual exfoliation.
  • Does an OK job degreasing skin.
  • Self-heating action has no impact on skin.
  • pH is above what is optimal for salicylic acid to as an exfoliant.
  • Salicylic acid is more effective in a leave-on product.
  • Contains fragrance, which puts skin at risk for irritation.

Biore At-A-Glance

Strengths: Provides complete ingredient lists for every product on the company Web sit; improved cleansers.

Weaknesses: Known for their pore strips, which aren't as helpful as they seem; lots of products that contain alcohol and/or menthol, neither of which improve the look or function of pores; the sole sunscreen option lacks the proper UVA-protecting ingredients.

This drugstore line wants you to know it is serious about keeping your pores unclogged. They pledge that their products will rid your pores of the dirt, oil, and grime that can cause them to enlarge to "manhole-sized proportions." Although that size is clearly an exaggeration, most of the claims Biore makes also stretch what's possible. For example, neither their products nor the manner in which they function take into account the fact that pore size is more often than not genetic and controlled to a large extent by the oil glands that lie beneath the skin,which are themselves controlled by hormone activity, and none of that can be affected from the outside in.

None of the Biore products can shrink the oil gland or help keep it unblocked, and that is the only surefire way to reduce pore size. One of the bonuses of taking prescription Accutane for acne is that in most cases the patient's pore size becomes remarkably smaller due to the manner in which this potent drug works internally. We are not suggesting anyone should take Accutane simply to shrink large pores. But we do suggest it would be better to stop believing that skin-care products that claim to do so are the answer. Effective skin-care products (including some items in the Biore line) can remove or absorb excess oil, which makes pores less noticeable, and a well-formulated cleanser will remove grime and surface oils without drying skin, which temporarily makes pores look slightly smaller. And believe it or not, sun protection plays a role in pore size. As skin becomes more sun damaged, it becomes thicker and unable to exfoliate normally. The buildup of dead skin cells coupled with thickened skin can make pores expand. This can be remedied by using a well-formulated AHA or BHA product along with daily application of a broad-spectrum sunscreen, products that Biore lacks.

That's the extent of it, which is why to a large extent (no pun intended) pore size is something that you must learn to live with, because beyond avoiding sun damage and trying Accutane, there is little that can be done to change it. However, the outlook isn't as bleak as it may seem. With conscientious skin care and proper use of makeup, you can successfully minimize the appearance of pores and prevent them from enlarging any further.
