Description
For skin that's tight by morning and flat by three. Tight after cleansing. Flat by 3pm. Makeup sitting on top instead of sinking in. That's dehydration, not dryness — skin short on water, not oil. A hyaluronic serum to pull water in, a centella booster to keep it there, and a mist for the top-up. For you if: Skin feels tight after cleansing and flat by 3pm, and makeup sits on top instead of sinking in. Why these, together: Dry skin is a type you're born with. Dehydrated skin is a state — it happened this week, and you can fix it. Water alone doesn't stay in skin — it evaporates, and that's the whole problem this set solves. THE MOST pulls water in. LIQUID PANACEA strengthens the barrier that has to hold it there. DEW HALO tops it back up through the day. Take away any one of the three and the other two stop working properly. Three products, $74. Bought one at a time, $105 — so the set saves you $31. Results shown are after 28 days of use. What it does: Fixes the tightness you feel right after cleansing. Skin still looks hydrated at 3pm, not flat. Makeup sinks in instead of sitting on top. Keeps water in rather than just adding it — that's the whole difference.

How to Use
1. THE MOST on damp skin. Three or four drops immediately after cleansing, while skin is still wet. This one matters: applied to a dry face, a humectant will pull water out of you instead of into you. 2. LIQUID PANACEA into your moisturiser. Two or three drops mixed in, morning and night — this is the step that stops the water evaporating again. 3. DEW HALO whenever skin goes tight. Held at arm's length, eyes closed. Over makeup is fine. Desk, plane, mid-afternoon.

Stefaniia A. (5/5)

Lightweight and Hydrating ✨

"I love how lightweight and comfortable this feels on my skin. It absorbs beautifully without feeling heavy or greasy, and it layers well with the rest of my skincare routine. My skin feels soft, hydrated, and refreshed after applying it. I also really enjoy the simple packaging and how easy it is to incorporate into my daily routine."

Laura C. (5/5)

One of my favorites!

"It provides intense hydration, improves skin texture, and truly imparts an incredible glow. It has a very lightweight texture that leaves no sticky residue after application. I highly recommend trying this serum and am confident you won't be disappointed."

Maryna S. (5/5)

Transformed my skin's plumpness!

"Currently this is my favorite hydrating serum. It has great effect on my dry skin. I use it AM and PM. I'm out of my 2nd bottle and already ordered the 3rd one. I'm confidently recommending this product. It does its job pretty well."

Eva A. (5/5)

My faithful friend for many years)

"I like to combine this serum with my products in the morning and evening. It perfectly complements any of my routines and is always pleasant to use The Most. Ideal moisturising option for oily and combination skin"

A. V. (5/5)

Unexpectedly very cool product

"I didn't expect anything from this mist, but in the end it turned out to be one of the best refreshing products of this summer) Mist is always in my car and I enjoy using it every day. He just makes you better all day long"

A. V. (5/5)

Calming serum for oily, rosacea prone skin

"PSA Liquid Panacea is one of the few serums that actually helps my oily, acne-prone skin without causing irritation or breakouts. It keeps my skin calm, hydrated, and much less reactive while using acne medication. Lightweight, non-greasy, layers beautifully under moisturizer and SPF, and really helps with redness and dehydration. The only downside is the size - I run out of it way too fast."

Ais (5/5)

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!"

Ilzira (5/5)

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."
