Just kidding. No glass is involved in the process of achieving a "perfectly smooth and intensely hydrated complexion with an all-over sheen," notes Refinery29

It has recently become quite a popular Instagram trend - but what exactly is involved?

According to Alicia Yoon, founder of Peach & Lily, glass skin is the idea of having insanely translucent skin.

“It's a sign of youthfulness and it's one of the most strived-for qualities in Korea. However, this combination of ultra-smooth texture and super translucency can be hard to achieve with products alone,” Yoon told Refinery29

The steps to achieving a baby-like complexion requires dedication and is all in the layering of hydrating products, adds founders of Glow RecipeSarah Lee and Christine Chang, for Allure. But, in the end, you'll have blemish-free, almost-flawless, dewy-looking skin.

Apart from keeping hydrated and eating healthily, Yoon further explained that the process is two-fold and requires an exfoliator to buff your skin this will allow it to have such a smooth texture. Remember, dull skin is due to a buildup of dead skin that also makes your complexion look tired, so exfoliating will slough off your top layer of skin and boost collagen.

NOTE: Just remember never to over-exfoliate as this could lead to an excess production of sebum which often leads to breakouts.

For the second potent step, you will need a hydrating serum to give off that glass-like appearance. If you want a more natural shine, Reader's Digest suggests you apply less of the serum and let it soak into your skin overnight. Then, repeat until the process becomes a habit.

Convinced? If not, know that the youthful-looking Pharrell apparently "exfoliate[s] like a madman", and LeAnne Dlamini notes a Clarins serum as her best-kept beauty secret.

NOTE: Again, remember to exfoliate within reason and as recommended for your skin type and skin concerns.
