Review: Algenist – Double AA Barrier Serum

Where to purchase: Available at LookFantastic (UK): HERE / LookFantastic (US): HERE / Feel Unique: HERE / Sephora: HERE

Price: £80

Volume: 30ml

Made in: Germany

What is it + What does it do: A serum containing antioxidants and skin-barrier fortifying ingredients to help protect and improve the condition of the skin.

The company claim: it helps defend the skin against environmental aggressors + protecting the skin from pollutants (due to the inclusion of Antioxidants). Through the use of Niacinamide + other antioxidants, this is also supposed to help minimise the look of wrinkles.

Supposedly Good for: All Skin Types

What I think: I agree all skin types (even sensitive skins) could use this. I do think Oily/Combo Skins > Dry Skins, but if you’re applying this under a moisturiser, then Dry skins would enjoy (as this contains emollients).

Vegan?: Yes

Cruelty Free?: Sells in China, so not fully yet.

How long does it last after opening?: 12 Months

Packaging: Plastic Bottle with a cap and then a pump – lightweight as well. Easy to travel with (and I had no spills).

Directions: Apply after cleansing and toning to the face, neck and décolleté. Follow with a moisturiser.

How I use it: As this is slightly heavier than more watery serums, I used this as a moisturiser. The silicone base + emollients in here meant that this still retained the moisture on my skin. I used about 3 pumps for the face and neck.

Key Ingredients: Niacinamide (Anti-Blemish, Moisturising, Skin-barrier reinforcing and brightening). Ascorbic Acid (Vitamin C – Antioxidant + Brightening, but probably quite a low amount). Phloretin, Ergothioneine, Epigallocatechin Gallate, Tocopheryl Acetate (All Antioxidants as well). Retinyl Palmitate (Increases Skin shedding to reveal smoother and brighter skin, good for sensitive skins). Aspartic Acid, Alanine, Serine, Valine, Isoleucine, Proline, Threonine, Histidine, Phenylalanine (Amino acids which work to reinforce the skin’s barrier + draw moisture into the skin), Arginine (also helps reinforce the skin’s barrier). Epigallocatechin Gallate (Soothing).

This also contains Alguronic Acid (sourced from Algae) which forms a film on the skin and also helps protect it from environmental pollutants.

What I like:

  • Packaging that you can travel with (also lightweight packaging)
  • Lightweight
  • Fragrance + EO Free
  • Didn’t worsen my skin
  • I like the cocktail of skin-beneficial ingredients (less to think about since it’s all in there)

What I don’t like:

  • Expensive
  • Not sure about the % of these actives included, so I would still use Retinol + Vitamin C products separately on the side.

Overall Rating and Conclusion: 4 (nearly a 3.9)/5 – I liked this product! I’m unsure as to whether it’s worth the £80 price tag however. I think if you can afford it and you’d like a nice skin-barrier boosting and protecting serum, then this is a nice addition (not solution). However if you are willing to purchase serums separately i.e. Vitamin C Serum, a Niacinamide Serum + a retinol serum, you could go for that (also you would know the % of actives included, whereas with this, you don’t). I did enjoy using this and have now finished using this without any issues.

Would I purchase?: I think it’s too expensive for the effect.

Dupe?: Another product that aims to rebuild + restore + fortify the skin’s barrier is the Isntree Bifida Ampoule (Link HERE). It does have a different texture (that is a watery serum. And I do not recommend using when the skin is sensitised by heavy retinol use).

My Skin Type: I am acne prone and have slightly dehydrated combo skin. My skin is usually tight where the cheeks and eye area is and the outer parts of my face. My T zone is oily. My skin isn’t a fan of thick/heavy formulas so I opt for lightweight formulas to prevent it from clogging up. My skin doesn’t like essential oils either and I try to avoid fragrance when I can.
