100 years ago, I worked for Lancôme.  I was obsessed, the skincare smelled and felt amazing, the textures were unreal, the global "innovations" and "1st time" ingredients had me sold.  Then I learned what a marketing ingredient was, and moved on to other products, until recently.  I was given the Advanced Génifique (fake French word) Youth Activating Serum and threw it towards the back of my product queue, until a slot opened up and I decided to give it a try.  The second ingredient is "Bifida Ferment Lysate",  as fermented ingredients are typically high on the list of Korean Essence products I decided to do a little research.  There are no real studies on the effects of this particular bacteria on the skin, but I will tell you this, I'm on my second bottle.  This concentrate absorbs super quick and feels like an instant boost of moisture.  Lancôme bosts some moderate results across all major skin concerns, targeting it to all skin types and ages, so it truly is an "All Skin Type" product.  It features a dropped that premeasures the perfect amount every time you open it; I used this morning and night and it lasted me over 4 months

I finished my first bottle, moved to another product for the past few months and am happy to say I'm glad there was a second bottle in my queue to use.  At $105 for a 1.69oz bottle it may not be the most affordable extra step in your routine,  I give it 4/5 Stars and recommend it to anyone wanting a boost of hydration, radiance, and improvement in texture.  Use after essence and before or as your serum.
