What they liked

  • Gentle for a retinaldehyde, hydrating formula
  • Citrus scent, though noticeable

What they flagged

  • Contains fragrance, unsuitable for daytime use

What the gurus are saying

This retinaldehyde serum earns consistent praise for visible brightening and a surprisingly comfortable, hydrating texture that many found gentler than expected on sensitive areas like the neck. The formula's supporting cast of niacinamide, ceramides, and hyaluronic acid helps ease dryness, though one note: it does contain citrus fragrance oils, so best reserved for nighttime use. Those new to retinoids may want to start once or twice weekly with days in between, then build up as skin adjusts.

"Maelove was so early with retinol. Their retinol product is actually one of my favorite smelling products of all time, even though that's kind of illegal for a dermatologist to say."

"The Maelove Moonlight Retinal Serum has retinaldehyde, which is one-step closer to retinoid conversion than retinol, and may be slightly more effective than your regular retinol."

"May Love Moonlight Super Serum is another retinaldehyde that I like, and that's probably the first retinaldehyde product I've been exposed to, and I love that one. It has a nice cool color, as well, and so gentle and hydrating. May Love has done a great job with their products."

"If you've done retinol and you want to upgrade, go for retinaldehyde. Maelove Moonlight or Avène retinol products are great. Those are gentle retinaldehyde and that's only one conversion step away from becoming active retinoic acid versus retinol needs two conversion steps."
You Don't Need All Those Products — A Derm's Guide to Simplifying Skincare
"If you want to work on anti-aging including hyperpigmentation, fine lines or wrinkles, go for a retinol or a retinaldehyde. The OG has always been Maelove Moonlight Serum, which has been out for a long time well before all of this big explosion of retinaldehyde. This came out I believe in 2020, 2021. Retinaldehyde is more potent than retinol. I love retinaldehyde because it's more potent theoretically than retinol and you don't have a lot of irritation like the prescription stuff I would prescribe like tretinoin, tazarotene. Tazarotene is very notorious for causing irritation."

"Some brands have done a good job with retinaldehyde, which is much more unstable and harder to create. I've talked about Maelove's Moonlight Retinaldehyde Serum."
Dermatologist Explains: Which is the Best Retinol for You!
"The moonlight retinaldehyde serum is a nice retinaldehyde product that is in a dropper bottle, fairly affordable. They've done a great job with this and just a few drops to the face at bedtime and then apply your moisturizer over it. Great stuff. Studies have shown that it can help with fine lines and wrinkles even more so than retinol but it could be a little bit more irritating because it's more potent. There are trade-offs to it. Always start slow, maybe starting off like two to three times a week and then working your way up to every night slowly. But always moisturize after your retinaldehyde."

"I really love this formulation because it is super brightening. There are other ingredients in here that benefit our skin even further. For example, there's niacinamide in here and this ingredient really helps to fade dark spots and post acne marks, but it can also brighten the skin at the same time. Retinaldehyde does that also. So I feel like this combination really gives that extra kick to your skin to brighten everything up. There's also hyaluronic acid, ceramides, squalane, aloe. There's green tea. There's a lot of great ingredients in here to keep the skin nice and hydrated and nourished. It's a wonderful formula. You're getting 30 mls of product and this is a true serum type of texture. It has like this nice milky texture, but super lightweight. Very thin, very watery, and this one spreads really nice."

6 BEST MAELOVE SERUMS TO TARGET SIGNS OF AGING | THESE ARE SUPER IMPRESSIVE AND THEY WORK!
"This is actually quite nice. I didn't experience any irritation, no tingling, no nothing. I did use this a handful of times on my face just to test this, but I was also using this on my neck as well because I use Tretinoin on my face but I can't bring it down my neck, so I usually use retinols or products like this that my neck can tolerate well too on those Tretinoin nights so that I can treat the neck and the chest area, and this actually worked really nice on my neck. I didn't have any additional irritation, no retinol burn, no nothing, and I was shocked because I was just waiting for that irritation to happen and it didn't, so I was really impressed with that. Now this has some additional ingredients also like niacinamide, ceramides to strengthen that skin barrier. I love when a retinol product has ceramides in it. This also has squalene, hyaluronic acid, it also has tea extract as well, and the list goes on. So again, it is quite hydrating when you put this on your skin, your skin does feel quite comfortable, and it does have that milky consistency and it is yellow in color as well. So if you're looking for something that is a little bit stronger than retinol but one step down from retinoic acid, then I would say give this a try. I really do think this is a great one."

"I love this a lot and I think it's a really nice one, especially if you want to enter the retinaldehyde world. I would say if you're using this, don't pair it with vitamin C because it's best to keep this as that main product just so that you don't develop more irritation and dryness because that is possible when you're using a retinaldehyde. Maybe just pair up hydrating things with this, a really good moisturizer, maybe a hydrating serum, and if you're someone that uses essences and toners then use those before this."

"The Maelove Moonlight Retinaldehyde Serum does have fragrance in it, contains bergamot oil, orange oil, and grapefruit oils. They're not strong but there is a citrus scent to it, so if you're going to use this be aware of it, certainly don't use it during the daytime. This one contains 0.1% retinaldehyde. It also contains cloudberry seed oil and green tea."

"Moonlight Retinaldehyde Serum, it is 0.1% retinaldehyde. So these for me, I know they have the same amount of retinaldehyde in them. I like them both. If money's tight and you're trying to decide between these two, I would definitely go with the Naturium because this one is 1.7 oz, the Maelove is 1 oz, and they're about the same price, they're both about $30, so you get almost 3/4 an ounce more in the Naturium. But as I said, I do love both and will continue to use both."

"I have been able to use retinaldehyde on my neck and for the last few years I've used Maelove Moonlight super serum which is a retinaldehyde serum and I love this serum. I had been using a different retinaldehyde before this one but I finished up my last bottle of that over the course of 2023 and went whole hog just into Maelove Moonlight serum."
Best BUDGET Anti-Aging Skincare from the Drugstore!
"I've been using a retinaldehyde serum for a long time now that I love. I use it on my neck because my neck is too sensitive to use my prescription strength retinoid there. I've been using the M Love Moonlight Retinaldehyde Serum, which is a 0.1% formulation. Until recently, this was definitely the least expensive way to get a retinaldehyde into your skincare routine."
Yay
"My favorite of mine in this 0.1% category is the Maelove Moonlight Retinaldehyde Serum. This is divine. It has that very rich coloration you would expect from a high strength retinal and this is really rich and creamy, has much more of an emulsion-like texture. I love this Maelove one. I think it's absolutely fabulous. It has a very unique texture and is beautifully well formulated. These are the sort of strengths you want to begin with if you don't have too sensitive skin. They're going to be hydrating which is nice and you can still use them alongside your moisturizer."
Yay
"Another over-the-counter retinoid product that I really like is the MAY LOVE Moonlight Retinol Super Serum. This serum uses something called retinaldehyde rather than retinol which is one of the more common molecules found in over-the-counter retinoids, and retinaldehyde is a little bit more potent than retinol because when retinol is incorporated into the skin it has to undergo two conversion steps to become its most active form whereas retinaldehyde only has to undergo one conversion step to become its most active form. This serum also contains niacinamide, an antioxidant, and it has ceramides which help make it a little bit more hydrating and protective of the skin barrier."
Yay
"I use moonlight which is 0.1% retinaldehyde in it. A lot of people have concern about putting retinaldehyde on their skin because maybe you're sensitive, maybe you're worried about dryness or irritation, but this has other really great supporting ingredients in it. It has ceramides, it has hyaluronic acid, so it's really going to be gentle on your skin considering you're putting a retinoid on there. You can use this actually morning and night. Do I want you to use a retinaldehyde product every single night? No, I do not. Because I think it's important to take a few nights off as rest nights to rest and reset your skin and to take one or two nights off a week to do an exfoliation night."

BUDGET Skincare Swaps! | The Budget Dermatologist
"This contains retinaldehyde as the hero ingredient. It's in a good concentration and has a really good overall hydrating formula. It's in a serum dropper bottle situation and you just need a little bit and then blend it into your skin. It smells nice and it feels really hydrating on the skin, and then that yellow color kind of absorbs into the skin and doesn't show up too crazy."
Reviewing the Strongest Peptide Serum! | Anti-aging Treatment for Wrinkles
"Maelove is one of my favorite clean skincare brands. This contains retinaldehyde, which is the strongest form of retinoid you can get over the counter without a prescription. It's a budget option that also contains retinaldehyde, it's a little more affordable if you just want something different, more of like a serum. That's an amazing serum."

"A longtime favorite of mine by Maelove, the Moonlight Retinaldehyde Serum. It has 0.1 percent retinaldehyde in it. So it's a good dose, but it's a really hydrating formula. So I love this for mature or dry skin types or if you just want extra hydration in your skin. This is such a nice feeling product on the skin."

"This is a very popular product that is often sold out on their site. This one has a 0.11 concentration of retinaldehyde in it and this is less than half the price of the Avène product that I use. It's actually a really interesting product for this price. It has niacinamide in it and ceramides so it's very nourishing to the skin."
Top Budget Pick Retinaldehyde Serum for Anti-aging | The Budget Dermatologist
"I use this serum at night because I think retinoids will be the most effective for you before bedtime. This product has retinaldehyde as the form of retinoid, which is stronger than retinol and is literally the perfect option for someone with sensitive skin that still wants results. One of my favorite things about the May Love Moonlight Super Serum is that they tell us exactly how much retinaldehyde is in this product and I love a brand with transparency. This moonlight serum has a retinaldehyde concentration of 0.11 percent. May Love formulates their products to really be strong for maximum results yet still gentle so that they can actually be used by people with sensitive skin. The product contains niacinamide to strengthen and soothe the skin barrier, ceramide to strengthen and restore the skin barrier, and is formulated with squalane and bisabalol to also soothe the skin and protect against redness and irritation. First you are going to see improvement in your skin tone and radiance after just a few uses, and then you will start to see improvement in your fine lines and wrinkles at the three to six month mark. Both the one by May Love, which is more affordable, and another retinaldehyde option by Avene are my two favorite retinaldehyde options for anti-aging."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Retinoids

Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

Source: DermNet

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Source: DermNet

Ceramides

Ceramides are part of the skin's own barrier, and moisturisers built around them have evidence for holding water in and settling the tightness and flaking that come with a damaged barrier.
