Description
Water first, acids second — the night shift. Skin does most of its repair while you sleep. This is the version where you help. A hyaluronic acid serum to put water in first, then a multi-acid and probiotic night serum that works on texture while you don't. For you if: You wake up with texture, and skin feels tight the moment you're out of the shower. Why these, together: If acids have ever stung, this is usually why: they went onto skin that was thirsty. Water first, then the acid — and suddenly the same actives are comfortable. Your skin does its repair overnight. This is the version where you help it. THE MOST goes first — hyaluronic acid at several sizes, so the water reaches more than the top layer. GOALS goes on top and works on skin that's already hydrated, which is why the same acids feel far gentler. Both are water-based, so they layer without pilling. Two products, $67. Bought one at a time, $89 — so the set saves you $22. Results shown are after 28 days of use. What it does: Puts water back into skin that feels tight by morning. Resurfaces overnight, while you're not touching your face. Softer texture by the end of the first week. Probiotics keep the skin's own balance steady while the acids work.

How to Use
1. THE MOST on damp skin. Three or four drops straight after cleansing, while your face is still wet — hyaluronic acid needs water to hold on to, and dry skin in a dry room is the one case where it can work against you. 2. GOALS on top, at night only. A pump pressed over face and neck. Start every other night for the first two weeks, then nightly if skin is comfortable. 3. SPF every morning. The acids work overnight; the sun undoes them by lunchtime.

"I’ve been using the GOALS Multi Acids & Probiotics Perfecting Night Serum and really like how my skin looks in the morning. My skin feels smoother, softer, and more refreshed without feeling too heavy or greasy. It gives a nice healthy glow and helps my skin texture look more even.

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!"
