Lunar Bloom Retinal Serum

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 skin renewal and boosting collagen. 

Like Retinol, its well-known relative, Retinal must convert to its active form, Retinoic Acid, before it can do its job. The difference? Retinol requires 2 conversion steps, while Retinal needs just 1—allowing it to get to work faster.

Whether you use one, two, or all four of our serums is totally up to you and your skin needs!

Lunar Bloom Retinal Serum is our go-to for dialing back the look of fine lines & wrinkles by promoting collagen production and skin renewal.

Brighten Up Vitamin C Serum is our go-to for brightening dull-looking skin and targeting stubborn dark spots, uneven texture and tone.

Mountain Glow Serum is our go-to for an instant dewy boost. It restores moisture and supports collagen & barrier health, so skin looks youthful and firm.

Forest Water Hyaluronic Serum is our go-to for deep hydration. It plumps skin, helping it appear firmer with fewer visible fine lines.

At night, apply 1-2 pumps of Lunar Bloom Retinal Serum before applying the moisturizer of your choice. No matter your skin time, we recommend starting slowly (using up to 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, as retinoids can increase your skin’s sensitivity to the sun!

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

Short answer: Yes. We chose Retinal for its potency (it’s 20x stronger than Retinol!) so we only needed 0.1% in our formula to deliver results, as well as supportive actives like Ceramides to help soothe skin. Also, because Retinal requires fewer steps to convert to its active form, tiny doses are often gentler than high doses of Retinol (which take twice as long to activate, often irritating skin more).

For those with sensitive skin, we recommend starting slow (using 2-3x a week) to let your skin adjust. You can also try making a “Retinal sandwich” when starting out: applying a layer of moisturizer both before & after your serum.

Lunar Bloom Retinal Serum is unscented.
