This specialty product is an example of what not to do when formulating a product to minimize pores. First, aside from the name, there really isn't anything special about this product. The blend of numerous silicones and polymers creates a texture that smoothes surface irregularities and has a temporary filling effect on pores this is only one of dozens of other products that have this same benefit but without the problematic ingredients L'Oreal added.
L'Oreal's claims "Pore Vanisher works on three dimensions to shrink pores: depth, number and size. But it's not possible. Nothing it contains can truly reduce the number of pores you have. Each person is born with all the pores they'll ever have.
However, pores do change in size and depth over time due to hormones causing clogged pores and from sun damage weakening the pore's support structure, but again, Pore Vanisher falls down in fixing those problems.
Because Youth Code Pore Vanisher contains a potentially irritating amount of alcohol, fragrance ingredients known to be irritating, and a form of menthol (menthyl lactate) whose cooling sensation won't make pores smaller, it's a bad idea for pores of any size. All of these combined can damage skin and the irritation can stimulate nerve endings at the base of the pore, causing potential problems. What kind of problems? Such stimulation can trigger excess oil production, which in turn makes pores bigger, not smaller!
One more comment: L'Oreal refers to the ingredient perlite as being able to strengthen and tighten pore walls. There's no research showing that to be possible. Perlite is a silica-based rock that has no special benefit for enlarged pores. It's similar to silica in that, when milled and included in skin-care products, it imparts a silky feel and powder-like finish.
To strengthen pore walls, there are several things you can do such as exfoliate with a salicylic acid (BHA) exfoliant, be sure to get all your makeup off every night, don't irritate your skin which will stimulate more oil production, and protect your skin from the sun every day! Surprised about sunscreen improving pores? It's true! Sun exposure damages the supportive elements in the skin and those elements also help keep pores properly shaped and "tight." As those support elements become damaged, the pore has less scaffolding to help it maintain its shape, essentially becoming "loose" and enlarging.
- Silky texture has a subtle (temporary) "filling" and smoothing effect on enlarged pores.
- The texture and finish work well under makeup.
- Cannot reduce the number of pores you have or the size of the pores; rather, it simply masks the appearance of larger pores.
- Contains irritating ingredients that can potentially make enlarged pores and oily skin worse if used daily.
- Highly fragrant formula poses a strong risk of irritation.
Irritation, whether you see it on the surface of your skin or not, causes inflammation and as a result impairs healing, damages collagen, and depletes the vital substances your skin needs to stay young. For these reasons, it is best to eliminate, or minimize as much as possible, your exposure to known skin irritants, especially when there are brilliant formulas available that do not include these types of problematic ingredients (Sources: Inflammation Research, December 2008, pages 558–563; Skin Pharmacology and Physiology, June 2008, pages 124–135, and November-December 2000, pages 358–371; Journal of Investigative Dermatology, April 2008, pages 15–19; Journal of Cosmetic Dermatology, March 2008, pages 78–82; Mechanisms of Ageing and Development, January 2007, pages 92–105; and British Journal of Dermatology, December 2005, pages S13–S22).
