Retinaldehyde is one of the leading exfoliating ingredients in today’s skincare market. It’s a derivative of vitamin A and promotes skin cell turnover, improves skin tone, and helps to unclog pores. Furthermore, it helps to thicken the skin’s dermis which resultantly slows down wrinkle formation.

It’s perfect for anyone that’s looking for the anti-aging effects of a retinoid, with added exfoliation properties.

IDEAL FOR: Anti-Aging, Dull Skin, Fine Lines, Wrinkles, Hyperpigmentation and Scarring

SKIN TYPES: Normal Skin, Dry Skin, Aging and Mature Skin

Key ingredients:

Retinaldehyde (the least irritating form of Retinol): This encourages skin cell regeneration and collagen production, while conditioning the complexion to encourage quicker skin rejuvenation.

Peptides: These work to rebuild and repair damaged cells and signal the skin to produce collagen, slowing the aging process.

Lactic Acid: This acid melts away dead skin cells to reveal a brighter complexion.

1,3 beta glucan: This activates the scavenger cells that work to remove dead and dying cells to help promote internal cell turn over and therefore the synthesis of collagen, elastin, and other structural proteins.

Synth 6 (Palmitoyl tripeptide -38): This wrinkle filler derived from tripeptides compromised of 6 amino acids helps build and rebuild the skin and forms the matrix of collagen.

Chronoline (caproyl tetrapeptide -3): Chronoline boosts collagen production, and activates skin repair, while reducing the appearances of fine lines and wrinkles.

L-hyaluronic Acid: This contains a natural moisturising factor that continually hydrates the skin by attracting water molecules.

Shake lightly and apply 1-2 pumps to cleansed skin, morning and evening.

Osmosis serums are highly concentrated using source ingredients, and if you are new to this range we advise just a few little things.

Begin by using only 1/2 to 1 pump of serum per application for at least the first week and build up from there if needed. For optimum results, massage the serum into the skin followed by the Osmosis Boost Peptide Activating Mist.


Skincare is a ritual:

If you find the serum is struggling to be absorbed, you should take time to massage your serum into the skin thoroughly until fully absorbed. Repeat the use of the Boost Peptide Activating Mist.


Please note:
It may take a week of use before your skin becomes accustomed to the use of the rich ingredients within Osmosis serums and starts absorbing the products effectively.

    This is purely the best as it’s much stronger that any vitamin A product and it’s not irritating at all! My skin is very plumped and much better looking since I started this serum!!! Love it!!

  2. Margarita

    My absolutely favourite product!!! Definitely works well for anti-aging !

  3. Mia

    I have been using this serum for 7-10 day and am in love with the product.
    It has yellowish natural colour, smells really nicely and has the highest concentration of vitamin A. My skin is absorbing it in second .. and I see how it is getting smoother and more hydrated.

    Before I was using Obagi which was prescribed by doctor – it is not even near the same effect!

  4. Isabella

    I was really lucky when I found this serum with Retinal (Retinaldehyde) – retinal is the same as retinol but it does not irritate your skin. I started with their Level 2 serum and now doing Level 4 – very happy! Vit. A is the most important for anti-aging but very often skin feels very sensitive.. I had to stop using Obagi and Medic8 because my skin did not coop. This product is the best what happened to me)))))

  5. Juliet

    I love love love it! It is doing something magic with my skin!! Use it at night (it is brown and you cannot use it at day time) and immediately see how skin is tighter next morning.

  6. Natalie

    dermoi! made my life so easy!!! I can now buy my favourite products locally with speedy delivery.

  7. Ella

    I still don’t feel any irritation while using vitamin A serum every day – it’s very pleasing as my skin is usually very reactive on other serums&creams with high concentration of vitamin A. My skin loves it)))

  8. Suzy

    It has the highest concentration of vitamin A and it does not irritate at all
