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.

  • Use 1-2 pumps at night before you apply your favorite moisturizer. Start by using 3 times a week and build up to nightly use. Daily AM sunscreen use recommended.


    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. 


    Already loving the other Ursa Major serums in your routine? We suggest using Vitamin C in the morning and either layering Mountain Glow over Lunar Bloom at night, or alternating every- other-night between the two serums. 

     

    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: How do I recycle this product? 

    A: When you run out, just give the glass container a rinse and recycle it at home. Because the plastic pump is a mixed material, it can’t be recycled at this time. 


    Q: What is the aroma?

    A: Lunar Bloom Retinal Serum is unscented.

      Another Excellent Product

      I started using Lunar Bloom last month and it is soothing and not at all harsh on my skin. I have had texture problems all my life and the Ursa Major line of products are transforming it to a visible smoother with an even tone. Pores are much less noticeable. Lunar Bloom is wonderful to tighten and soften lines. Thank you fir giving me more beautiful skin and more confidence .

      Lunar Bloom

      I’m over 60 with sensitive skin and this is the only retinol-based product that doesn’t irritate my face. It is so light, not greasy or sticky, and is perfect under the Golden Hour cream. After years of failed efforts to find the right products for my touchy skin, (even making my own botanical creations when nothing else worked) I’m so impressed with Ursa Major skin care!
