Launched in 1952 and currently owned by L’Oréal, Biotherm is a French beauty brand that specializes in skincare and bodycare. (It used to carry makeup products.) The brand’s Blue Therapy range is positioned as an anti-aging range, and Serum-in-Oil Night is one of its latest releases.
Blue Therapy Serum-in-Oil Night (30ml, £44) has a gel consistency when dispensed and it turns into a half-serum-half-oil consistency when applied. The product spreads well on the skin but it can take some time for it to be absorbed into the skin.
Some of the main moisturizing ingredients in this product are glycerin, glycine soja oil, caprylic/capric triglyceride, isononyl isononanoate, pentylene glycol, stearic acid, rosa canina (rosehip) fruit oil, ribes nigrum (blackcurrant) oil, helianthus annuus (sunflower) seed oil, and palmitic acid.
The product contains antioxidants such as glycine soja oil, algae, algae extract, rosa canina (rosehip) fruit oil, astaxanthin, ribes nigrum (blackcurrant) oil, haematococcus pluvialis (astaxanthin) extract, and tocopherol (vitamin E). (Blackcurrant oil contains gamma linolenic acid (GLA), which has antioxidant properties.)
It contains adenosine, which is an anti-irritant and a cell-communicating agent. Gamma linolenic acid (GLA) in blackcurrant oil also functions as a cell-communicating agent.
It contains ceramide 3, which helps repair the skin’s barrier system.
It is paraben-free.
However, the product contains alcohol (denatured alcohol). It is sixth on the ingredient list and the amount is fairly large. (Alcohol can cause free radical damage.) It also contains benzyl alcohol, which in itself can be irritating, but the amount is very small.
It contains rosmarinus officinalis (rosemary) leaf extract. It can function as an antioxidant but its fragrant components can be potentially irritating.
It contains fragrance (parfum) and other scenting ingredients. The fragrance is quite pleasant but some people may find it to be on the strong side.
With a fairly large amount of alcohol, I hesitate to recommend this product to anyone. If formulated without alcohol or other problematic ingredients, this would be an outstanding product which contains a wealth of skin-benefiting ingredients.
