What the gurus are saying

This serum delivers a silky texture and visible hydration boost that gurus praise, particularly for those skipping retinol during pregnancy or breastfeeding, since it offers similar firming and anti-aging effects without the active. The pearl finish sits nicely under makeup and between a hydrating mist and moisturiser, making it especially helpful for dehydrated skin. The main caveat is the price tag: gurus note it's a genuine luxury step rather than a skincare essential, so best suited to those with budget room for indulgence.

"I've been trying their Luminous Silk Serum, love this. It's kind of a creamy serum. I was thinking it would be a watery serum but it's not, it's a very creamy serum and it has their signature amino acids and peptide blend that is throughout all of their products."

"The Silk Serum is for firmer, blurred, radiant, smoother, brighter skin all in one. If you love the benefits of retinol and you love the benefits of vitamin C but you've got more delicate skin, it's got three key ingredients: upcycled cranberry extract which helps with skin turnover and collagen synthesis, sea fennel which is super soothing, and Hadasei-3 which is green tea, rice and seaweed that's fermented twice. It goes 34% deeper into the skin than water so it's able to carry the active ingredients down deeper to do its best work. It's a stroke of genius."

"This is a lovely serum. It has like this beautiful pearl in it. It's great for underneath makeup and it's a really great step for like after a mist and before moisturizer, especially if you have very very dry skin or you have dehydrated skin. I was using it when my skin was really really dehydrated, especially when I had to do makeup, and I would do a mist, I would do the serum, and then I would do some kind of a moisturizer and it was just like such a nice combination. That said, it's super expensive and it's definitely not necessary. If you have some money to spend on skincare and you want to indulge in a little bit of luxury skincare, it is really nice and it does make your skin glow. If you wear it on a day when you're not doing your makeup, just on your face, it doesn't make your face look like shiny or sparkly in any way. It just makes your skin look hydrated, which is really nice."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
