YSL Youth Liberator Serum Foundation

October 1, 2013

I have been obsessing over YSL Youth Liberator Serum Foundation for months, and was overjoyed when I found it in Hong Kong last month! Why is it that Singapore has to lag behind every other country in the world with product launches?!??

Anyway, for those of you who are wondering what the fuss is all about, Youth Liberator Serum Foundation is the latest foundation from Yves Saint Laurent. It is infused with YSL’s Forever Youth Liberator Serum which contains the patented “Glycanactif complex”, to help the skin look more radiant, plumped and smoother.

The biggest question on my mind was, how is this Youth Liberator Serum Foundation different from YSL’s Le Teint Touche Eclat Foundation?

The biggest difference: Coverage

As I mentioned on my review of YSL’s Le Teint Touche Eclat Foundation (here), I found it to be somewhat on the lighter side in terms of coverage, and too runny in consistency to be able to blend quickly & easily. YSL’s Youth Liberator Serum Foundation offers medium to full coverage. It is much better in terms of consistency, thicker than Le Teint Touche Eclat, but not so much that it renders it difficult to blend. Instead, I found it easy to layer on to provide more coverage as needed.


Serum Foundation contains a new Color Glow Complex that counteracts dullness and gives skin a brightening effect. To give you an idea, here’s one of those half-half mug-shots below.  So glamorous, I know…but it should give you an idea of how much brighter my skin looks with the Serum Foundation.  Also, my pores seem smaller, and my under-eye bags are better concealed with the coverage.

The thing to note is, because of this light-enhancing effect, the shades for Serum Foundation do not quite correspond with Le Teint Touche Eclat. I have swatched both B30 shades of the 2 foundations for your reference.  I layered them on thick here so you can see better… but Serum Foundation appears brighter, leans more towards beige whereas Le Teint Touche Eclat appears browner.  This comparison should also give you an idea of the difference in textures and coverage that I had described earlier.

And the biggest similarity: Finish

Fans of Le Teint Touche Eclat will love the same luminous finish, which I associate very strongly as the YSL signature.  However, for those of us living in humid tropics, this dewiness has a tendency to turn oily quite fast.  The way I make it work, is by following the YSL Rituel Lumiere (described here) – first apply a makeup base, followed by the Serum Foundation, and set it by dusting a light layer of powder over (YSL Le Teint Touche Eclat Compact Powder Foundation works marvelously).  Even with all the layers, you will never look cakey or overly done, as Serum Foundation will still look natural, just much more matte!  However, if you’re the sort who generally slaps on 1 product and go, this may seem like a lot of work and is best reserved for special occasions.  Unless of course you have blessedly non-oily skin, in which case, this will be absolutely lovely!

A word on Lightbulb….

Due to their coinciding launch dates, I found myself trying to compare YSL’s Forever Youth Liberator Serum Foundation against Shu Uemura’s Lightbulb Foundation (briefly reviewed here).  For those who have experienced Lightbulb, the Serum Foundation is completely different.  Serum Foundation gives a velvety (dewy) finish whereas Lightbulb gives an almost matte yet glowy finish.  In terms of coverage both offer medium to full coverage, but I found Lightbulb to be just a tad more so than Serum Foundation.

Lastly, on longevity…

Unfortunately, due to its dewy nature, I found YSL Youth Liberator Serum Foundation to turn oily and oxidize much more readily on me (than Lightbulb).  However much it brightened up my face, I found myself having to blot and powder up by mid-day.  Even then, by the end of the day, there is some fading and quite a bit of sheen.  I didn’t actually compare side by side, but I think Serum Foundation lasts slightly longer on me than Le Teint Touche Eclat.

In conclusion

Though the skincare benefits are nice to have, there is really no good way to measure that without actually going through a whole bottle (which will probably take me another year or so given my considerable stash).  I do quite enjoy using YSL Youth Liberator Serum Foundation, the brightening effect and coverage helps me look wide awake with a mere 4 hours of sleep.  I just wished it lasts longer on me!

    Hey Linda,
    Thanks for the review. I have been wanting to try this a lot. It’s nice to read the comparison between this and lightbulb. I am loving lightbuld dewy finish and after reading your post, it makes me feel even more curious to see the matte glowing effect on my face. Can’t wait to grab a bottle of this!

      Hi Meryl, thanks for your stopping by and your kind comment! I love Lightbulb too, but i find that more “matte” than Serum foundation…. which is more velvety & dewy. Do try it out and let me know how you like it! xoxo
