Why It’s Special

What’s Retinal?

Short for retinaldehyde, Retinal is a form of Vitamin A. It helps rewind the look of fine lines and wrinkles by promoting renewal and boosting collagen. 

Super potent, surprisingly gentle

Retinal is 20x more potent than Retinol. That’s why we chose it! It’s super effective in small doses, which means our formula taps into its full superpowers without setting off your skin.

Leave fine lines behind

Whether you’re looking to turn back the clock or get a head start, Retinal’s specialty is smoothing the appearance of fine lines and wrinkles.

Smooth things over

Retinal plus micronutrient-rich plant actives work their magic each night, so you’ll notice improved skin texture and smaller-looking pores.

Q: What is Retinal?

A: Short for retinaldehyde, Retinal is one of the strongest forms of Vitamin A available without a prescription. It helps rewind the look of fine lines and wrinkles by promoting renewal and boosting collagen. 


Like Retinal’s widely-known “cousin”, Retinol, both derivatives need to go through a conversion process at the level of the skin to reach their active state: Retinoic acid. Traditional Retinol is 2 steps away from this conversion. Since Retinal needs only 1 step, it’s able to get to work more quickly, and your skin is able to use it more effectively. 


TLDR: We like to think of Retinal as Retinol’s hard-working, super-skin-renewing cousin that you’ve always wanted to hang out with (and now you can).  


Q: How and when do I use this product? 

A: As part of your nightly ritual, apply 1-2 pumps of Lunar Bloom Retinal Serum before your moisturizer of choice. Start out slowly (3 times a week) to allow your skin to acclimate, before building up to nightly use.


Non-negotiable: pair this nighttime serum with a daytime SPF (we’re partial to our Force Field SPF 30), as retinoids can increase your skin’s sensitivity to the sun.


Q: How do I work this product into my existing serum routine?

A: One recommendation would be using Vitamin C in the morning and layering Mountain Glow over Lunar Bloom at night, or alternating every other night between the two serums. 


Q: Is it pregnancy safe?

A: This product is not recommended for those who are pregnant, nursing, or attempting to conceive. 


Q: What skin type is this suitable for? 

A: Lunar Bloom Retinal Serum works great for all skin types, even sensitive and acne-prone skin. This serum can keep both mature and young (and everywhere in between) skin glowing strong. 


Q: Is this safe for sensitive skin?

A: We chose Retinal specifically because of its efficacy—it’s 20x more potent than Retinol! That means we only needed to use a tiny bit (0.1%) in our formula. A tiny amount of potent Retinal is much easier on your skin than a larger amount of traditional Retinol—because your skin can’t absorb all that Retinol, and what's not absorbed can sit on skin and potentially cause unwanted side effects. We also added barrier-loving ingredients like plant-derived Ceramides and Hyaluronic Acid. to soothe even the most sensitive skin types. 


No matter your skin type, but especially those with sensitive skin, begin using gradually (3 times a week) to allow your skin to adjust. And don’t forget daily SPF protection.


If you’re worried about how extra-sensitive skin might react, you can build a Retinal sandwich—AKA applying a layer of moisturizer both before and after your serum—when starting out.


Q: What is the aroma?

A: Lunar Bloom Retinal Serum is unscented.

    Moon ritual

    I apply during the full moons for more fun. Sometimes your skin needs a break once in awhile and then a boost now and again. The full moon is my boost! Absolutely amazing.

    Pleasantly surprised

    Ordering products from Facebook has proven to be a major mistake for me. Ursa Majors skin care has been the surprise outlander. The products have been a nice change and my skin loves it.

    I miss this in my nightly routine when I run out

    I’ll celebrate my 40th birthday this year and I’ve really enjoyed adding this to my nightly routine. I have switched all of my products to Ursa Major and especially love my once a week routine of using their mud mask scrub, then this product and finishing off with the golden hour cream. I wake up with fresh glowing skin. I don’t plan on having any fillers or changing my appearance surgically as I age so appreciate Ursa Major giving my skin its natural beauty each time I use their products.
