I’m shopping OSEA’s Labor Day sale for a chance to save more on skincare I already love.

OSEA is the clean-formulated skincare brand from the sea that I turn to when I want hydration, effective formulas and a little more from my daily routine. Founded in 1996, before “clean beauty” had even become a household term, the brand is built around seaweed-powered skincare that is also clinically tested.

From Wednesday, Sept. 2 through Monday, Sept. 7, OSEA is making its End of Summer Offer even more appealing with free gifts at different spending tiers. The deal I’m most interested in is the easiest to hit: Spend $125 and get a free Ocean Eyes Age-Defying Eye Serum, a $58 value. For me, that’s a useful addition rather than a throwaway freebie, especially if I’m already restocking my favorite hydrating essentials.

Spend $170 and the perks increase to two free gifts, including a travel-size Anti-Aging Body Balm, for a combined value of $78. At $225, shoppers get three free gifts, including a full-size Dream Night Serum, bringing the combined gift value to $166.

There are also three sets that automatically come with the free Ocean Eyes Eye Serum. The new limited-edition 30 Years of Bestsellers Set is $148 for a $240 value, a 38% savings, and celebrates OSEA’s 30th anniversary. The Undaria Body Collection is $142 for a $180 value, while the Dream Bio-Retinol Trio is $162 for a $208 value.

I like that these sets make it easy to build a routine without having to guess which products work well together. OSEA’s formulas are hydrating but still feel purposeful, and the clean formulations make these products feel like a worthwhile upgrade to my current skincare lineup.

And there’s another layer of savings: All sets and promo codes can stack for additional savings. That means I can potentially combine the existing value of a set or sale with the Labor Day gifts, then use code NYPOST for an additional 10% off.

For me, that makes this a good time to upgrade the skincare I’m already shopping for. The offer runs through Sept. 7, so I’d shop before the Labor Day promotion ends — especially for the limited-edition anniversary set.
