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.


  • Retinaldehyde: Retinaldehyde is the star of A²: a revolutionary form of vitamin A that is proven to deliver results 11x faster than RetinOL. RetinAL is more potent, faster-acting, and does not create inflammation in the skin like the other forms of vitamin A.
    Encapsulated and stabilized for maximum potency, A² will leave you with visibly firmer, smoother, and brighter looking skin.

  • Peptides: A² is formulated with two clinically proven anti-aging peptides.
  • Palmitoyl tripeptide-5 acts on the specific skin receptors and stimulates the production of collagen in our skin cells. It firms our skin, reduces the appearance of wrinkles and fine-lines. It makes your skin look healthier and fresh.
  • Caprooyl Tripeptide-3 is known as the "anti-wrinkle peptide." Studies have shown this peptide to help diminish visible lines and wrinkles in just 28 days. Additionally, it targets the skin's elasticity and rejuvenates mature complexions. Caprooyl Tripeptide-3 comes from TGF-ß, a growth factor supporting the fibroblasts encompassing the epidermis, resulting in stronger, smoother skin.

  • Antioxidants: Antioxidants such as niacinamide, THD Ascorbate (tetrahexyldecyl ascorbate), resveratrol, vitamin E, and green tea work together to scavenge free radicals, reduce inflammation, and help skin cells repair their DNA and fend off damage caused by daily environmental aggressors.


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.

    3rd bottle!

    Posted by Peggy on 6th May 2024

    This is my third bottle and my skin has never been so clear and smooth! I used to use Osmosis retinaldehyde but switched because this is a higher potency and I love it has no essential oils which are damaging to the skin. And boy was I wow'd. This not only exceeded the Osmosis formulation but my resuolts are just amazing! Much much better and I love supporting a woman in business. This product has far has done wonders for my skin. Thank you and I hope others give it that try!
