'L'Occitane just reformulated their most cult serum so we asked 12 women to put it to the test.'

Thanks to our brand partner, L'Occitane

If I could name one of the most buzzed-about beauty trends that will never go out of style, it's glowing skin.

But maintaining that luminous, healthy-looking glow has its challenges. Our lifestyle habits, environment and what we're using (or missing) in our skincare arsenal can often lead to dullness. And while there's plenty of duds out there on that third point, sometimes it's knowing what formulas and products are actually worth introducing and sticking with, because they're just that good.

L'Occitane's Immortelle Reset Oil-in-Serum is one of those products.

If you're a skincare devotee, you're probably very familiar with the cult status of the brand's Immortelle skincare collection. Now, they've recently enhanced the formula of their iconic Reset Oil-in-Serum which harnesses the powerful essential oil from the immortelle flower, patented by L'Occitane for its strong antioxidant properties and ability to boost the skin's radiant appearance.

This oil-in-serum contains over 3,000 golden bubbles in each bottle that preserve the Immortelle essential oil. Those sensitive to fragranced skincare can also rest easy: the product's fresh scent naturally comes from the immortelle flower, which gives the product its golden glow.

Now, reformulating a product that so many beauty buffs already know and love can be risky business. Luckily, the redeveloped Reset Serum does pinky promise to improve signs of sensitivity, strengthen the skin barrier and deliver a revitalised and radiant-looking complexion — now clinically proven to increase hydration and glow after a single use, and also over time.

For example, in several consumer tests, results revealed a +14 per cent visible boost in glowy skin after 6 hours, +26 per cent visibly more hydrated skin after 8 hours — and after a 4-week trial period, this upped to +40 per cent visible boost in glowy skin and +31 per cent more hydrated skin.

Fancy! So, we were excited to have 100 women with a variety of skin types in our You Beauty Panel to test the reformulated Reset Serum IRL and report back, particularly those with sensitive skin.

Here are some of their honest verdicts.

Bernadette, 34: "This has saved my dry skin."

"This has saved my dry winter skin. I've been using some heavy duty moisturiser to help with my dry skin this season. On the first night as soon as I put on this serum, I was instantly impressed. It glided on and soaked into my skin leaving it feeling and looking hydrated! After a week, my skin is glowing! Super impressed and thankful to have found this to add to my nightly routine."

Erna, 44: "I'm converted."

"I'm absolutely in love with this new Reset Serum! I'm converted! It's truly beautiful. I have dry, sensitive skin that tends to be quite flaky during winter. While I didn't see an immediate difference after the first two nights, by the third night, my skin felt noticeably less dry.

"The serum also has a lovely fragrance, layers beautifully with other products, and leaves my skin radiant and smooth each morning. I can definitely see and feel the difference."

Natalie, 34: "Beautiful texture."

"Beautiful and unique texture! I like how it felt lightweight giving plenty of moisture to the skin. It layers well with other serums and moisturisers in my nightly routine, but feels hydrating enough to wear alone too."

Alicia, 31: "I woke up with glowing supple skin."

"Very good experience after using for a week so far. This serum feels and smells so luxurious on the skin. I woke up with glowing, supple skin and really enjoy using it."

Stephanie, 49: "My skin woke up looking brighter."

"This L'Occitane serum was such a pleasure to use, from the quality pump and feel of the packaging, to the way my skin woke up looking brighter and more glowy. The serum glides on and does not leave your skin feeling sticky or too slick. It has a very subtle, fresh scent, and I loved that it wasn't too fragranced. I'd recommend and repurchase this product again, five out of five!"

Rachael, 50: "My skin is dewy and soft."

"This product is stunning. The serum melts into your skin overnight, my skin is dewy and soft. I feel beautiful, and seeing a visible difference after one week, looking forward to using it long term. I'd definitely buy it again."

Rebecca, 32: "My skin glowed after only a week."

"I love this Immortelle Reset Oil-in-Serum serum! I can't believe how much my skin glowed after only a week. From the first use I could see less redness and my skin was so glowy. As a sensitive skin girly, I found the formula so compatible with my skin, especially with the changes in weather causing irritation. The scent was so calming for my evening routine as well. Would definitely purchase this serum in the future."

Alison, 39: "My skin is more hydrated."

"The packaging was lovely, as expected from L'Occitane! The bottle is nice and heavy, you can see the beautiful golden bubbles suspended in the serum through the glass.

"It's a very light serum, and these bubbles dissolve into the skin easily. There is a subtle floral fragrance that may be a bit much for some, but I found it disappeared completely once dry. I feel my skin is more hydrated using this product, it layers well with my existing products and is a very nice addition. I will keep using it, and would recommend it to friends! I'd give it four stars out of five so far."

Callie, 32: "Left me with a night 'glow'."

"Loved this serum, I'd happily recommend it! I used two pumps each night after cleaning my face and before using moisturiser. Very light and absorb very quickly — even left me with a night 'glow'. I would definitely buy this after this bottle is finished. The bottle is honestly so beautiful to have on display, too."

Emmeline, 48: "I have very sensitive skin and had zero reactions."

"I loved the luxe packaging, it looks so premium and I couldn't wait to try. It has an unique texture of encapsulated oil bubbles, and easily absorbs into the skin. It also has a lovely natural fragrance.

"I have very sensitive skin and had zero reactions, which felt lovely. My skin felt hydrated and fresh the next day after the use, with only this serum and a moisturiser used. While it's too early to see long-term changes, I'm a happy customer and would rate this five out of five."

Aimee, 39: "It feels like a real treat."

"It feels like a real treat and ritual to use the L'Occitane Immortelle Reset Oil-in-Serum. It smoothes on really nicely, and then I added my usual actives and then night moisturiser over the top. I think my skin appears a bit smoother and more even toned alright, so I'll happily continue using it."

Angela, 44: "My skin is smoother and brighter."

"Love this product, and having the opportunity to discover it! Great packaging, smells fantastic and lovely to apply. My skin felt hydrated, and appeared smoother and brighter after a week of use. I am planning on adding it to my morning routine too!"
