How to use
| How: | Apply 1-2 pumps to clean, dry face. Allow to absorb. Avoid eye area. |
|---|---|
| When: | Use at night, after cleanser. Use 1-2 times a week, or as needed. For added hydration, or for those with more sensitive skin, top it off with a thin layer of moisturizer, such as Advanced Protection Cream, Atmosphere Protection® Cream, Dream Night Cream, or Seabiotic® Water Cream. Cleanse in the morning, then follow with your regular skincare routine. Always use sunscreen. |
| Pro tip: | Seaglow Resurfacing Scrub and Seaglow Overnight Serum should not be used together, instead use on alternative days as to not over exfoliate skin. |

I absolutely LOVE this product and what it does for my skin! It's so effective but still super gentle. I don't get any redness or irritation when I use this and I wake up with soft, smooth, hydrated, glowing skin. It's a miracle-worker!
- JTJaime T.Verified BuyerRated 5 out of 5 stars7 months agoGood so far!
I’ve only used this a few times as it recommends just 1-2x a week. Doesn’t burn like other AHAs I’ve tried before.
