Gotu kola (Centella asiatica) is one of the most versatile botanical ingredients in skincare, effective as a store-bought serum, a DIY mask, or even a simple tea-based toner. Its key compounds stimulate collagen production, calm inflammation, and help protect against sun damage. How you use it depends on what your skin needs and which format fits your routine.
Why Gotu Kola Works on Skin
Gotu kola contains a group of active compounds, with asiaticoside and madecassoside being the most important for skin. Asiaticoside directly triggers your skin cells to produce type I collagen, the structural protein responsible for firmness and elasticity. Madecassoside does the same through a related signaling pathway. Together, they essentially tell your skin’s fibroblasts to ramp up collagen output, which slows naturally with age.
Beyond collagen, gotu kola is a strong antioxidant. Animal studies on UV-exposed skin show it restores the activity of key protective enzymes that get suppressed by sun damage, while reducing lipid peroxidation, a marker of oxidative stress in skin cells. In those studies, oral gotu kola extract significantly reduced wrinkle formation and improved skin texture in UV-damaged skin, with higher doses producing more pronounced results.
What to Look for in a Product
If you’re buying a gotu kola serum, cream, or essence, the concentration and standardization matter more than the brand. Effective formulations in research use Centella asiatica extract at concentrations between 0.2% and 1.0%. The pharmaceutical-grade benchmark is called TECA (Titrated Extract of Centella Asiatica), standardized to 40% asiaticoside, 30% madecassoside, and 30% asiatic and madecassic acids. You won’t always see this breakdown on a label, but products that mention “standardized extract” or list asiaticoside content are generally more reliable.
At minimum, pharmacopoeial standards call for not less than 1% asiaticoside and 0.5% madecassoside within the extract itself. A product simply listing “Centella asiatica” without any standardization info could contain very little of the active compounds. Korean “cica” products tend to be well-formulated for this ingredient, though the key is checking that the extract appears high on the ingredient list rather than buried at the bottom.
Where It Fits in Your Routine
Gotu kola works well at several steps in a skincare routine, and it doesn’t have strict pH requirements like vitamin C or chemical exfoliants. That flexibility is one of its advantages.
- As a serum or essence: Apply after cleansing and toning, before heavier creams or oils. This is the most common and effective delivery method for concentrated extracts.
- As a cream or moisturizer: Cica-based creams work well as your final moisturizing step, especially if your skin is irritated or recovering from a procedure.
- As a toner or mist: Lighter formulations can be used as a hydrating layer right after cleansing, or spritzed throughout the day for a moisture boost.
- As a spot treatment: Creams or balms with gotu kola can be applied directly to scars, blemishes, or patches of irritation.
You can use gotu kola products both morning and evening. In the morning, layer sunscreen on top as you normally would. At night, it pairs especially well with treatments that might irritate your skin (more on that below).
Pairing With Other Ingredients
Gotu kola plays well with most skincare actives, and it’s particularly useful alongside ingredients that tend to cause irritation on their own.
With retinol, gotu kola acts as a buffer. Retinol commonly causes dryness, peeling, and redness, especially during the first few weeks of use. Gotu kola helps reinforce the skin barrier, retain moisture, and reduce inflammation, which means fewer flare-ups and a smoother adjustment period. Apply your gotu kola serum or cream first, let it absorb, then layer retinol on top. Or use a product that combines both.
With chemical exfoliants like AHAs, BHAs, or PHAs, gotu kola serves a similar calming role. Some multi-acid serums already include Centella asiatica to offset sensitivity during exfoliation. If yours doesn’t, apply gotu kola afterward to soothe the skin.
With hyaluronic acid, the pairing is straightforward: hyaluronic acid pulls in moisture, and gotu kola helps the skin barrier hold onto it. Layer hyaluronic acid on damp skin first, then follow with your gotu kola product. Vitamin C and gotu kola can also be used in the same routine without conflict, though applying them at different times of day (vitamin C in the morning, gotu kola at night) keeps things simple.
DIY Methods
If you prefer making your own preparations, gotu kola powder and dried leaves are widely available online and in herbal shops. These DIY approaches won’t have the precise standardization of commercial extracts, but they’ve been used in traditional skincare for centuries.
For a simple face mask, mix a teaspoon of gotu kola powder with enough aloe vera gel or raw honey to form a paste. Apply to clean skin, leave on for 15 to 20 minutes, and rinse with lukewarm water. Both aloe and honey add hydration and their own soothing properties.
For a toner, steep a tablespoon of dried gotu kola leaves in hot water for 10 to 15 minutes, strain, and let it cool completely. You can apply this with a cotton pad after cleansing or pour it into a spray bottle for a refreshing face mist. Adding a splash of rose water extends the hydrating effect. Store it in the refrigerator and use within a week, since there are no preservatives.
For targeted scar or dark spot treatment, mix gotu kola powder with a small amount of shea butter or coconut oil to create a thick balm. Apply it to the affected area nightly. This approach takes consistency, as visible improvement on scars typically requires several weeks of daily use.
To make a collagen-supporting facial oil, combine a few drops of gotu kola extract (available as a liquid tincture) with a carrier oil like jojoba or argan oil. Massage into your face and neck before bed. Jojoba oil closely mimics your skin’s natural sebum, so it absorbs well without feeling heavy.
Safety and Skin Sensitivity
Gotu kola has a strong safety profile in cosmetics. The Expert Panel for Cosmetic Ingredient Safety has concluded that Centella asiatica extract and its derivatives are safe at the concentrations currently used in skincare products, when formulated to be non-sensitizing.
In a patch test study of 110 people, a cream containing Centella asiatica extract caused zero cases of allergic contact dermatitis. A separate study of 52 people found that about a third experienced very mild, temporary redness during repeated patch testing, but no lasting sensitization. At high concentrations (30% extract tested on guinea pigs), gotu kola was classified as a weak sensitizer, but commercial products use far lower concentrations.
If you have reactive or allergy-prone skin, do a patch test before applying any new gotu kola product to your full face. Apply a small amount to the inside of your wrist or behind your ear, wait 24 hours, and check for redness or irritation. This is especially worth doing with DIY preparations, where concentrations are less controlled than in commercial formulas.
How Long Until You See Results
Gotu kola isn’t an overnight fix. For general skin calming and reduced redness, most people notice improvement within one to two weeks of consistent use. For collagen-related benefits like improved firmness, reduced fine lines, or fading scars, expect to use it daily for at least six to eight weeks before changes become visible. Collagen remodeling is a slow biological process, and the compounds in gotu kola are stimulating your skin’s own production rather than filling in gaps artificially. Consistency matters more than concentration here.
