I would like to know which brands are actually bestsellers and popular in Korea? 

I recently purchased the BB Lab Collagen supplement and wanted to know if it's well-known?

It would be great if someone could recommend me products for oily and ageing skin too. Thank you.

I felt that for a Vitamin C serum, compared to other serums this was highly nourishing and gentle. It did also improve my skins overall radiance, reducing any dullness I suffer from.

I received this product for free from Picky and Dr. Ceuracle in exchange for my honest review. Vitamin C in powder form is the purest, I absolutely recommend this product to everyone. The fact it is contained as a powder before you dispense it to the liquid keeps it from depleting. This product left my skin visually brighter and has reduced the appearance of hyperpigmentation and fine-lines and wrinkles.

I received this product for free from Picky and Benton in exchange for my honest review.

This is a soothing, refreshing and hydrating toner. I loved how it refreshed my skin in this hot weather but also was gentle without irritating my skin. It clarifies the skin too, I don't suffer from any blemishes anymore but my skin definitely appears and feels clear.

The consistency is very runny like a typical toner, it contains some of my favourite ingredients which include bee venom and snail secretion, which are also potent anti-ageing ingredients.

Nothing at all, Its become a staple product of mine.

Coxir Intensive EGF Peptide Serum.
I received this product for free from Picky and Coxir in exchange for my honest review.

Suitable for all skin types:

This is an anti-ageing, rejuvenating serum. It strengthens the skin barrier, brightens the skin and firms. 

Key ingredients: 
EGF
peptide 
Collagen 

EGF is probably the lesser known ingredient of the three main ones. It increases skin cell renewal to repair the skin.
Peptides are an amazing ingredient, that diminish the appearance of fine-lines and wrinkles and make the skin firmer.
Collagen depletes in your 20's, the serums collagen will improve your skin elasticity and make it plump.

The texture of the serum is gel-like but as soon as you start to massage the product it literally melts into a runny, water-like consistency. The packaging states to massage the product in and I researched online Coxir mentions to tap it in for absorption, however this product is absorbed into the skin so quickly you don't need to massage much. I have oily skin and I was amazed at the quick absorption.

It's a product I've been using consistently, it firms my skin and skin barrier, leaves it soft, diminishes the appearance of fine-lines and wrinkles. I've also noticed it's great if you have dehydrated skin. It doesn't leave a residue behind and it's a product for people who don't have time to wait in the morning for their serum to absorb.
It can be used daily in the morning or evening. I've been using it throughout the day as due to prescription changes my skin has become dehydrated.

I received this mini product for free from Picky and Acwell in exchange for my honest review.

This pH balancing advance serum is multi-functional. It brightens, hydrates, encourages collagen production and plumps fine-lines and wrinkles. My skin was left smooth and soft.
