Our squalane comes from 100% plant-based, renewable sugarcane, then bio-fermented to create a beautiful end product — highly stable, totally sustainable squalane. Every drop of squalane in our products is derived in this eco-friendly way. Squalane is a non-polar, fully saturated, and very stable compound, resistant to oxidation and UV radiation. It is an exceptional moisturiser, preventing moisture loss and imparting suppleness and flexibility to your skin. Although the body produces its own version of squalane (known as squalene), the amount made and retained in the skin decreases over time. It peaks in our teens and then starts to decline in our 20’s, leaving skin rough, dry and vulnerable.


Our Arjuna Extract is a plant extract of pentacyclic triterpenes from the Arjun tree. It contains approx. 7% triterpenes of which at least 65% are arjunolic acid and 25% are asiatic acid. In the context of aging skin, triterpenes are valuable ingredients to counteract all visible signs of skin aging.


With age, the skin’s natural functions slow down. This starts in your 20’s and gets more pronounced over time. Women in their late 40’s or early 50’s experience a radical change, as they enter menopause – a major reduction in female hormone production by the ovaries that tends to occur over several years. This category of aging is also referred to as ‘hormonal aging’ and occurs as levels of estrogen decline. While many tissues are affected by this process, women having overcome the menopause transition (postmenopausal phase) experience major changes, especially concerning their skin. There is a marked change in skin structure and composition. Low estrogen levels result in weakening of collagen and elastin fibers. With decreased skin elasticity, the skin loses its property to extend and bounce back to its initial state. The skin is thinner and becomes more fragile. Due to reduced sebum production and a weakened skin barrier, mature skin often feels and appears very dry. Decreasing estrogen levels also result in a weakening of blood vessels and a decreased blood distribution in the skin (microcirculation). This further results in a shortage of nutrients and oxygen, and a diminished removal of metabolic waste products in the different skin layers. This contributes to slower cell turnover.


Our Arjuna extract has a very broad activity. It strengthens the extracellular matrix leading to improved skin density and resiliency. By strengthening the skin barrier and inducing skin sebum production, Arjuna extract reduces the signs of dry skin and protects the skin from external challenges. It also contributes to improved microvascular network, leading to better skin nutrient supply and promotion of cellular turnover. Relating these activities to mature and postmenopausal skin, Arjuna extract is a perfect ingredient to combat the signs and effects of hormonal aging.


The Vitamin F we use in Hydrating Serum comprises linoleic acid (C18:2), the main fatty acid, ~60% of the total, linolenic acid (C18:3) representing ~10% and the balance, arachidonic acid (C20:4). It is esterified to resist oxidation and remain stable. A deficiency in linoleic acid is linked to many skin problems – see our blog here for more details.

Use as required, especially on dry areas. Shake well before use to ensure the arjuna extract is well mixed.

    This is the best, most cost effective product I have purchased from Optoderm. It lasts you almost 6 months, and it is extremely effective in hydrating the skin.
    I can not go without it.

    Love to add this serum to my moisturizer. It only takes a drop or two and does not make my skin feel oily.
