Reviews

Great !!

"really enjoy using The Most serum. It has a light texture, absorbs fast, and feels very comfortable on the skin. It does not leave any stickiness and works well with my other skincare products. My skin feels more hydrated and soft. Happy with the purchase."

— Ilzira (5/5)

The ultimate drink of water for combination skin

"The Most by PSA is exactly what my skin was craving. Since I have porous/combination skin, I'm very picky about textures, but this serum is flawless. • Application: It spreads easily and absorbs in seconds. • Key Benefits: I’ve noticed a huge difference in my skin's moisture barrier. The Panthenol and Bisabolol really help soothe any redness, making it the perfect companion for a routine that includes acids or retinols. • Verdict: It leaves my skin looking bouncy and refreshed. It’s a versatile, high-quality serum that delivers on its promises. Definitely a repurchase for me!"

Hydrating, lightweight and actually works

"I’ve been using PSA The Most serum for about a week now, and I’m honestly impressed with how quickly I saw results. The texture is very lightweight and absorbs fast without any stickiness. It layers perfectly with my other skincare products and doesn’t pill under sunscreen or makeup, which is a big plus for me. After just a few days, my skin felt more hydrated, smoother, and less tight after cleansing. It gives that fresh, plump look without feeling heavy or greasy. I also noticed that it helps calm my skin when it feels a bit sensitive. I like that it’s simple but effective — just good hydration that actually lasts. It works really well both in the morning and at night. Overall, this is a great everyday hydrating serum, especially if your skin needs moisture without heaviness. I’ll definitely keep using it."

— Ilzira (5/5)

My hydration holy grail!

"I’ve been using The Most for a while now and it’s truly a game-changer. My skin is combined and porous, so finding a serum that hydrates deeply without feeling greasy is hard. This serum sinks in instantly and leaves my face feeling plump and ‘bouncy. ’ It layers perfectly under Silver Lining. My skin has never looked this healthy and glowing!"

— Ilzira (5/5)

A relief to use

"I’m usually skeptical of serums that promise everything, but this one is actually a relief to use. It doesn't have that annoying sticky finish that most hyaluronic serums do. It just feels like my skin is finally getting a proper drink of water. I put it on, it disappears, and suddenly my face looks less 'tired office worker' and more like a person who actually sleeps :)"

— Lina (5/5)

A gentle serum that works perfectly in my routine

"I really enjoy using The Most serum. It has a light texture, absorbs fast, and feels very comfortable on the skin. It does not leave any stickiness and works well with my other skincare products. My skin feels more hydrated and soft. Happy with the purchase."

— Ibrahim (5/5)

absolute lifesaver

"This serum is an absolute lifesaver. It feels exactly like a tall glass of ice water in the middle of a summer heatwave, it gives instant relief and deep hydration that my skin just drinks up."

— Kayra (5/5)

For acne skin one of the best

"I have acne-prone skin, so I constantly struggle with a damaged skin barrier because of active ingredients. This serum is one of my favorites — it makes my skin feel plump and well-hydrated, without any greasiness. It doesn’t clog my pores! I can say that for sure, because I’ve already used three bottles. The only downside is that it runs out very quickly — one bottle lasts me about three weeks (with dayly use)"

— Tatsiana (5/5)

Best serum

"The best moisturizing serum I've ever tried, a very smart formula that not only moisturizes but also strengthens the skin barrier."

— Верещагина Т. (5/5)

The best moisturising

"The serum perfectly moisturises the skin. I have retinol and acids in my care. This skin perfectly restores the skin after acids. The skin doesn't peel."

— Denys (5/5)
