Cosmetics is a science with deep roots in nature that, through research and innovation, finds new ways to promote well-being through the skin. Adaptogens are plant-based substances such as ginseng, maca, and ginger that help the body respond to physical, emotional, or environmental stressors.
Many of us have already used adaptogenic ingredients without knowing it. Used for centuries in Chinese medicine and Ayurvedic tradition, they are now enjoying a moment of great popularity, and cosmetic science has also begun to study their benefits for the skin.
What are adaptogens?
Adaptogens are plants that help the body modulate its response to stress. They are called adaptogens because they adapt to what the body needs, with a regulatory function.
The term was coined in 1947 by Soviet pharmacologist N.V. Lazarev to describe substances capable not only of regulating the stress response, but also of being tolerated during prolonged use. Since the 1940s, thousands of studies on adaptogens have been conducted, particularly in the Soviet Union, Korea, and China.
Research has shown, for example, that rhodiola (also known as arctic root) reduces the perception of fatigue in humans, while eleuthero (Siberian ginseng) has long been studied for its tonic action.
Adaptogens are generally plants or fungi that grow in inhospitable environments — deserts, high altitudes, and challenging terrain — and have developed a remarkable ability to adapt. They are among the most resilient organisms in nature.
Why stress shows on the skin
Stress and anxiety can worsen inflammatory skin conditions such as acne, rosacea, psoriasis, and eczema. High levels of cortisol affect the immune system and promote an inflammatory state that can aggravate existing conditions.
Adaptogens are thought to interact with the stress response system, which includes the hypothalamic-pituitary-adrenal (HPA) axis, involved in cortisol release. By helping balance cortisol levels, they may help limit excessive spikes and chronic increases.
This is the field of neurocosmetics, which studies the dialogue between the nervous system and the skin. Environmental factors also play a role: UV rays, pollution, blue light, and smoke.
An important clarification: a cosmetic product containing adaptogenic actives can improve the appearance and comfort of the skin and help it respond better to environmental stressors. It does not treat acne, eczema, psoriasis, or rosacea, which are conditions that should be managed by a dermatologist.
The benefits of adaptogenic ingredients
Adaptogens used in cosmetics work on two timescales: in the short term, they help the skin return to a state of balance after exposure to stress; in the long term, they help protect it from cumulative effects, including the signs of skin aging.
The two main mechanisms are antioxidant and soothing action.
Antioxidant action
- Protection from free radicals: UV rays, pollution, and stress promote their production in the skin. Antioxidants neutralize them, limiting oxidative stress that damages skin cells and accelerates premature aging.
- Collagen support: antioxidants such as vitamin C participate in collagen synthesis, the protein that gives skin structure and elasticity.
- More even skin tone: some antioxidants, such as vitamin E and niacinamide, help reduce the appearance of dark spots by acting on melanin transfer.
Soothing action
- Reduced sensation of irritation: soothing actives help reduce redness, itching, and feelings of heat.
- Support for blemish-prone skin: persistent inflammation can contribute to the appearance of imperfections; soothing actives help keep the skin more balanced.
- After sun exposure: extracts such as chamomile and calendula help calm the sensation of overheated skin.
- Maintaining barrier function: inflammation can compromise the skin barrier, causing dryness and sensitivity. Soothing actives help preserve it.
Adaptogens used in cosmetics include turmeric, which is rich in curcumin and useful for reducing redness and improving skin radiance. The list is long — from ashwagandha and rhodiola to goji berries and medicinal mushrooms — but molecules such as ceramides, niacinamide, and peptides are often the most effective in formulations.
The best adaptogenic ingredients
The primary goal of adaptogenic skincare is to strengthen the skin barrier. Products must address the demands of modern life — climate change and ongoing stress — by drawing on highly resilient plants.
Niacinamide (vitamin B3)
A powerful, restorative antioxidant that helps protect cellular energy and counteract the effects of UV exposure. It increases the production of ceramides, the lipids that keep the barrier healthy and resilient, and has a brightening effect because it reduces melanin transfer to keratinocytes. The complete guide can be found in the article dedicated to niacinamide.
Kudzu and Pueraria Lobata
Kudzu is the source of Pueraria Lobata, an extract that supports the components involved in synthesizing skin structure. It stimulates cell renewal, improving the appearance of fine lines, and is particularly suitable during postmenopause because of its high content of isoflavones. It also has a soothing effect that relieves redness and sensitivity.
Tephrosia Purpurea
Among the adaptogens selected by LeLang is the Tephrosia Purpurea seed extract, an Indian plant that grows in remote areas and has been used in Ayurvedic tradition. The extract, marketed as Neurophroline™, is used as a neurocosmetic ingredient: according to the manufacturer's tests, it reduces cortisol production in the skin while promoting the release of beta-endorphins, creating a perceived feeling of well-being.
How to choose products
When selecting an adaptogen-based product, consider the whole picture: the ingredients, the formulation, and, above all, your skin's needs. Choose well-documented ingredients, check the INCI list and the position of the actives, and consider the presence of fragrances or alcohol if you have reactive skin.
Adaptogens address different needs: some are soothing, such as chamomile and calendula, and are suitable for easily irritated skin, while others have a strong antioxidant action and are more suitable for pro-aging routines. The type of product in which they are included also matters: a cleanser stays on the skin for only a few seconds, while a serum acts for hours.
Skincare is a personal journey that is never the same for everyone. This is the principle behind LeLang's selection of highly functional, naturally derived ingredients to create formulations designed for every skin type. If you have a specific concern, consulting an expert remains the fastest way to avoid trial and error.
