  • Go-to hyaluronic acid serum
Size: 1 Fl Oz (Pack of 1)
Love this product! I’ve tried more expensive hyaluronic acid serums but this one is still my go-to. Less than $6 has never felt so good. Good molecules always has top tier products that don’t irritate my skin. This serum, in particular, goes on easy and absorbs quickly. You really feel and see the moisturizing and plumping effects within the first couple minutes. Honestly, I love putting a little on my lips. Moisturizing and filling and plumping in minutes. I often try other serums but I always have this one stocked in my vanity. ... show more

  • Great for dry/irritated skin
Size: 1 Fl Oz (Pack of 1)
This is honestly awesome and for a great price tag. I had post retinol irritation and it was pretty bad. My regular stuff that I use was not helping to hydrate my skin back and it actually kind of burned. I got this in hopes for a little more moisture and it did the job 10x better. My skin was smooth, hydrated, and even glowed! Helped with the flakes from retinol dryness. I am going to repurchase this little gem again. I also have sensitive skin and this hasn’t bothered me at all. ... show more

  • Great for oily/acne prone skin hydration and pregnancy stretch mark prevention!
Size: 2.53 Fl Oz (Pack of 1)
Been using this for several months on my face for hydration and on my body to prevent stretch marks from pregnancy! Great price, absorbs quickly into the skin, and it makes my skin feel so hydrated without it being heavy. It layers very well with my other skin care products. I have very oily/acne prone skin. The only spots I have stretch marks are where I wasn’t putting this serum! Once I spotted the stretch marks I started applying it immediately and it has definitely helped keep them from getting worse! ... show more

  • My Skin Drinks This Up — Simple, Hydrating, and Actually Works
Size: 2.53 Fl Oz (Pack of 1)
If your skin has been feeling dry, dull, or just “off,” this is one of those products that quietly fixes it. This hyaluronic acid serum is lightweight, super hydrating, and makes your skin feel instantly smoother without being sticky or heavy. 👉 Quick take: simple formula, noticeable hydration, and really easy to work into any routine. This is perfect if: • You’re dealing with dry or dehydrated skin • You want that hydrated, glowy look (without oiliness) • You use niacinamide or vitamin C and need a hydration boost • You want a simple, no-fragrance skincare product *HOW I USE IT* I apply this on slightly damp skin right after cleansing, and before my other serums/moisturizer. It layers really well with niacinamide, which I also use, and helps everything absorb better without pilling. *PERFORMANCE* This serum absorbs quickly and leaves your skin feeling soft and hydrated almost immediately. Over time, I’ve noticed my skin looks more plump and smooth, especially when I use it consistently. If you’re using niacinamide, this pairs really well because: • Hyaluronic acid hydrates and holds moisture • Niacinamide helps with texture, pores, and overall skin appearance Together, they give you that balanced, healthy-skin look without irritation. Also worth noting: • Fragrance-free (great for sensitive skin) • Lightweight texture (not greasy at all) • Doesn’t clog pores *VALUE* For the price, this is honestly one of those “why not have this in your routine” products. It’s simple, effective, and works well with other skincare — which makes it a really solid staple. *PROS* • Deep hydration without heaviness • Layers well with niacinamide + other skincare • Lightweight, non-sticky formula • Fragrance-free and gentle • Helps skin look smoother and more plump *CONS* • Needs to be applied on damp skin + followed with moisturizer to get the full benefit If your skin ever feels tight after washing your face… this is the step that fixes that instantly. If you’re trying to build a simple skincare routine that actually works, this is one of those foundational products you’ll keep reaching for. Edit: Spilled it on myself at the end of the video 😂 10/10 for hydration… even my clothes got some. ... show more
