Truology A² Advanced Retinal Serum .2% 1 fl oz | 30 ml
A² is a uniquely encapsulated and stable retinaldehyde serum that together with the most potent collagen stimulators and antioxidants, will improve sagging skin, smooth lines and wrinkles, and will increase skin elasticity.
Formulated with .2% retinaldehyde, A² uses the most potent, non inflammatory vitamin A for serious skin rejuvenation.
Directions: Use once a day in the evening. First cleanse, then apply A² over face, neck, and chest. Allow to absorb and then follow with other serums and moisturizer. For new users of A², application should be phased in gradually. Start with two nights a week for the first two weeks. Then go to every other night the following week. And work your way up to nightly application.

Real People, Real Results
I am so impressed with the new barrier restore ultra. It is so hydrating but doesn’t feel heavy at all. The texture is so silky feels amazing on the skin. The ingredients are top tier for anti aging as always. It pairs amazing with the Epicutis SPF definitely recommend.
I absolutely LOVE this new version and this is coming from someone who loved the OG. It's a little richer but in the silkiest way. It feels so good on my skin. I was a little afraid it would be too heavy but I couldn't have been more mistaken. My skin drinks it up immediately and feels more hydrated. Thank you for an even better version! I've never loved moisturizers. I've always preferred serums . . . until now.
This product is VERY good! Love the texture and how it applies. It leaves my skin smooth and glowing. I have noticed a slit disappearance of discoloration of old pimple marks and a small spot of hyperpigmentation i have, fading away. I have purchased a back up, as i would like to see this product continue to work. Consistency is KEY! Great job, Bri! Can't wait for the next product. You and your chemist, are AMAZING!
FANTASTIC serum! Leaves my skin so dewy and hydrated. Too soon to know if it is perfecting my skin, but it looks amazing upon application and feels like my skin becomes more youthful instantly . . . so for this alone, it gets my 5 stars!
Love this product. I apply it every night over my Isdin serum. My skin looks amazing. I get many compliments. I believe the Truology Barrier Restore has improved my skin and gives me a youthful appearance.Published date12/24/25
On my 4/5 bottle of this! Cannot like without this in my routine. Love this product. Zero irritation or dryness and get all the benefits of retinol product. My skin just glows!
I Absolutely Love This Skincare Product and I Absolutely LOVE The New Delivery System Of The Product, Much Better Than The Original Version, Great Product, Great Quality and My Skin Thanks You. I Can’t Remember the Last Time I Had Any Botox, I Get Compliments All The Time On How Great My Skin Is For My 65 Year Old Self And Even People Will Compliment Me In Front Of My Husband Lol 😂
I've used this (alternating with another strong Retinal product) for over a year now and it is one of my favorite Retinal products. I have mature, oily, acne prone skin and am very picky with my skincare regimen. I prefer a stronger strength Retinal and this doesn't cause any irritation. It also plays well with other products and doesn't leave any stain on my white bedlinen.
My favorite vitamin C. I’ve used 2 bottles so far. My skin is brighter and I love all the ingredients in this. The serum layers well with my other products and I use this twice a day. Will keep purchasing
I have mature, oily, acne prone skin and have found that I just prefer a 20% THD Ascorbate over other forms of Vitamin C. This serum is light, absorbs well and layers very easily with other products. No pilling with makeup etc. I love the additional anti-oxidants/actives in the ingredient deck and incorporating this serum (alongside a couple others) into my AM routine. I do find this a little more hydrating so tend to use it more in winter than summer.
I’ve been using C-Boost consistently since they started to ship internationally and I incorporate this product at night with my Truology Vita-A Serum, absolutely Love the new delivery system and I’m hoping that the other products will eventually all be like this, it’s much better than the twist cap, which I did have a couple of the twist caps break on two of my Barrier Creams and One on my Vita-A2 Serum, other than that, my skin has never looked so good and I hardly wear makeup anymore, I feel confident enough to leave my home with no makeup, just a tinted sunscreen.
My skin feels so moisturised, smooth, bright and bouncy with this serum. I could tell pretty much immediately when I added it to my regime. Worth every penny and IMO. This is a new staple for m. Love it!
Won’t be without this product! This is my go to for peptides. It has EVERYTHING my skin loves. Love how I can put it under my eyes as well. My skin is nice and hydrated and stays that way. Not greasy or tacky, just radiant. Brianna, your line is amazing! Ty!

Product FAQ
Vita C3 is a combination of 3 clinically studied vitamin C's, L-Ascorbic acid, THD Ascorbate, and MAP (magnesium ascorbyl phosphate). Truology C-Boost is THD Ascorbate. If you have sensitive skin or are sensitive to L-Ascorbic acid, I would use C-Boost. C-Boost is also great for drier skin types as it's a lipid base and more moisturizing to the skin.
Yes, you can use C-Boost directly under the eyes
No, Vita C3 should not be used directly under the eyes because L-Ascorbic acid can irritate the delicate under-eye skin
Both include peptides and barrier restoring ingredients, but Barrier Restore is lighter on the skin, while Barrier Restore Ultra contains more ceramides, peptides, and also ectoin to further hydrate even the driest skin types. Both products contain everything your skin needs to support a healthy skin barrier, decreasing irritation and inflammation, which leads to a plump and healthy barrier.
You can layer growth factors with the Truology Youth Renew Peptide Serum. Truology Youth Renew uses multiple peptides that perform functions similar to growth factor serums, such as stimulating collagen and elastin, decreasing inflammation, and promoting a healthy skin barrier. Therefore, a growth factor serum is not necessary but can certainly be used alongside Truology.
You don't need to avoid anything; it's great for all skin types.
It is orange due to the high potency of antioxidants but it will not leave a tint on your skin when massaged in. If you are experiencing any tint on your skin it means you are most likely using too much product. Truology is very active and a little goes a long way.
All Truology products are safe for sensitive skin and were formulated for everyone including those with sensitive skin
