Travel Size 5ml: $15 | Full Size 1 oz $68

I originally made this serum for my friend Katharine, who is sensitive to a lot of ingredients, but wanted something to combat problem skin that was also deeply hydrating. What resulted is a serum with three important goals: 1. Healing/combating acne, 2. Helping with discoloration/scarring and 3. Deep hydration.

Ingredients to help combat acne include Witch Hazel (Gentle fighter against acne, tightens skin, heals bruises, eases eczema & psoriasis), Aloe Extract (Anti-acne, anti-aging, moisturizing, reduces skin inflammation & stimulates the growth of new cells), Cucumber Extract (Non-irritating, anti-inflammatory, soothing) and Centella Asiatica Extract (antiviral, anti-inflammatory, wound-healing). Niacinamide and N-acetylglucosamine work synergistically with one another and with Aloe and Centella Asiatica to reduce hyperpigmentation from scarring. Deep hydration comes from luxurious Argan oil, skin-identical Camellia Japonica oil, and soothing, hydrating rose extract.

Hydra Serum--so much moisture and goodness that it could heal all seven of a hydra's faces. :)

Skin Type: Oily, Sensitive

Skin Concerns: Acne, Redness/inflammation
Soft, protected skin

I was searching for a niacinamide serum, and lo and behold! SB has crafted one with no only my favorite redness reducing ingredient, but aloe, camellia oil, and witch hazel as well. My skin soaks this mix right up, and looks soft, calm, and protected. No noticeable smell either, which is great since I'm picky about scents. My only complaint is that it can leave my skin a touch shiny. Not oily, but just tight and light reflecting. I'm guessing it's the thing film of aloe. No biggie! If I want to look super matte on certain days, I just use this at night instead of during the day under makeup.

Skin Concerns: Acne, Redness/inflammation
Lightweight hydration

I have sensitive, combination skin and wanted something to help add moisture to the dry areas without being too heavy on the oily areas of my skin. Hydra is great for adding moisture and soothing my skin while also helping my acne. It is a real multi-tasker that is gentle, soothing, and healing. Every time I use it, my skin feels refreshed.

Hail, Hydra??

You know I couldn't resist the MCU reference. :P But really ... Hydra I'm loving because it adds moisture without the weight/stickiness I tend to associate with products specifically designed to moisturize. I'm not sure what in the formula is giving me this result, but I'm also finding that Hydra seems to leave my skin a little less sensitive, a little less prone to inflammation. I have chronic inflammatory issues that affect my skin as well as my GI tract, so topical anti-inflammatories that don't a) goop up and peel off; b) smother my skin until it's itching just from the formula itself; c) contain steroids I can't handle over the long term OR d) smell like a combination of Old Man's Medicine Cabinet and some ancient recipe for Horse Liniment are a big WIN in my book!
I picked up the travel size when serums were on sale almost a month ago, mainly because I wanted to get free shipping (and, spoiler: a TS of Hydra is actually $1.95 CHEAPER than the standard shipping, because Life Makes No Sense). I didn't expect to love it as much as I do. Reminds me of the Strawberry Serum from Summer 2019 - and that's saying a LOT. Wish I'd bought the full size; will definitely buy again!

This stuff ROCKS

I have dry, ultra-sensitive, acne prone, aging skin with big ol' pores. I've never really found a moisturizer that could give me enough oil/moisture and keep it there until I found Hydra Serum. This stuff makes my skin dewy af, and the glow is fantastic. Along with my other SB products, the redness has diminished, less acne breakouts, lines and wrinkles noticeably reduced, and pores are smaller. I hope to never run out!! Its a staple in my routine. I'm even wearing much less makeup because my skin tone is more even.

Level up!

I have extremely dry, extremely sensitive skin, plus occasional acne. Hydra was the missing piece for me this winter. My skin soaks in Hydra like a dry sponge soaks up water. My skin feels hydrated but not sticky!
