Love my new sleep set!

Oh my goodness, I just got the Silk pillowcase and eye mask set and I absolutely love it! The silk feels so luxurious on my skin and hair, and the eye mask blocks out light perfectly. I've been sleeping so much better since it arrived. My hair looks smoother too, which is a big plus. I will definitely be shopping here again for gifts for friends!

Satisfied with my Travel set

I recently bought the Travel silk set because I needed something compact for trips. The packaging was simple but elegant, and the items inside (a small pillowcase and eye mask) felt premium. I used it on a weekend trip, and it definitely made a difference. The silk pillowcase kept my hair from getting tangled, and the eye mask was comfortable without putting pressure on my eyes. I was curious if the hyaluronic acid actually did anything, and while I didn't see a dramatic change in just a few days, my skin didn't feel as dry as it usually does after hotel stays. Ordering was easy on the website, and it shipped out within a couple of days. It reached me in California about a week after ordering. I'm considering getting a full-sized pillowcase for home now.

Good pillowcase, fast shipping

I bought the Mulberry silk pillowcase. It arrived quickly, about 4 days. The silk feels nice and cool. My hair seems less frizzy in the mornings now. Happy with the purchase.

Nice silk, delivery took a bit

I ordered the hyaluronic acid infused silk pillowcase and it's quite lovely. The material is soft and feels good against my skin; I do think my face feels a bit more hydrated. The quality seems solid for the price. My only real gripe was the shipping time. It took about 9 days to reach me in Texas, which felt a little long. Customer service was responsive when I inquired though. Overall, a good product, just factor in some extra time for delivery.

Does the hyaluronic acid actually stay in the pillowcase after washing? Or does it all just wash out after a few cycles?

M Mike V. 3 weeks ago
it's supposed to last a while, i wash mine pretty regularly and my hair still feels really good. they say it's woven in or something so it doesn't just disappear.

i was worried about this too, but it seems to hold up. i've had mine for months and it still feels hydrating.

Can you stack discount codes? I have a first-time buyer one and saw some influencer codes floating around.

A Amber Doyle 1 month ago
nah, they only let you use one code at checkout. tried it myself.

pretty sure it's just one per order. most sites are like that these days anyway.

Thinking of getting one of these pillowcases, but has anyone tried to return one? Is it a hassle or pretty straightforward?

A Amber Brooks 1 month ago
yeah returns were easy, did it last month. just follow their instructions on the site.

How do these compare to the Slip brand ones? Are they worth the price difference?

K Kevin K. 1 month ago
i've had both, the sleep in beauty ones feel a bit thicker and i definitely notice the difference with my skin being less dry in the morning. worth it imo.
