What it is
Plus Kirei Plus GG Base Serum is a Japanese booster serum, 100ml, used as the first step after cleansing. Its 6.5% glycylglycine plus an azelaic acid derivative work to hydrate and balance oil and water in pore-troubled adult skin, smoothing rough, bumpy texture. The watery, non-sticky formula preps skin without getting in the way of the rest of your routine.
Why it's different
It is built around 6.5% glycylglycine, a moisturizing ingredient aimed at rough, bumpy, uneven pore texture.
An azelaic acid derivative helps balance the oil and water that drive congestion and dryness together.
It layers in niacinamide, an APPS vitamin C derivative, ceramides, and amino acids, so it conditions while it preps.

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
What is glycylglycine and what does it do?
Glycylglycine is a moisturizing ingredient used to target rough, bumpy skin around the pores. At 6.5% here, it works with an azelaic acid derivative to smooth texture and balance oily, dry-prone skin.
When do I use it in my routine?
Use it as a booster first step, right after cleansing and before toner. Its watery, non-sticky texture preps the skin so the products that follow absorb well.
Is it good for oily, congested skin?
Yes. It is designed for adult skin that gets both oily and dry, with rough, bumpy pore texture. The formula focuses on balancing oil and water while smoothing the surface.
Will it feel sticky or heavy?
No. It has a light, watery, sarasara texture that absorbs quickly without tack, so it will not interfere with the toner, serum, or moisturizer you layer over it.

I can see how good it is when I use it occasionally. I will buy this lotion again from time to time.
It's neither good nor bad...If it doesn't suit my skin it can clog my pores, but this is good as it doesn't.
I've bought this so many times that I'd almost forgotten it existed. I have thin skin, so I don't like heavy products that leave a residue or make my skin feel strangely shiny. I prefer products that moisturize moderately and absorb easily. This one is exactly that: smooth and non-greasy. I bought it because it contains GG to combat pores and oiliness in the T-zone. Using it like a lotion and wiping it off in the morning has given me just the right amount of moisture, and it seems to tighten my pores. I also like the small amounts of vitamin C and ceramides it contains. It doesn't visibly eliminate pores, but it does have a moderate oil-controlling effect, and most importantly, it's easy to use, so I find myself reaching for it every day. As others have said, the GG hardens into a gritty mess, but it doesn't solidify in the liquid, so if you lightly wipe the opening after each use, it's not that noticeable. It's not flashy, but it's a subtle, essential item.
It's quite watery, so be careful not to use too much when you first start using it. I think it blends well with the skin. I'm not sure if my pores have shrunk yet, so I'll post again when I've used it all up. It doesn't have an unpleasant smell.
I bought this product because I wanted skin care products that would target inner dryness and control sebum. It may be because of the time of year, but since I started using it, I feel like my skin is less oily than before.
