Green Lemon Vita C Blemish Serum (2023 Version)

20% Ascorbic Acid (200,000 ppm) — Pure vitamin C and the main evidence-based active in the formula. At this high concentration, it provides antioxidant support and can help improve the appearance of uneven pigmentation and photodamage, but it may also sting or irritate sensitive skin.

56% Green Lemon Extract (560,000 ppm) — Forms the botanical base of the serum and provides additional antioxidant and skin-conditioning compounds. It should be viewed as supportive to, rather than equivalent to, the 20% pure ascorbic acid.

Ferulic Acid — An antioxidant that complements vitamin C and vitamin E. It is included relatively low in the INCI, so its exact contribution cannot be quantified from the ingredient list alone.

Tocopherol (Vitamin E) — A lipid-soluble antioxidant that complements the antioxidant profile of the formula and helps protect skin lipids from oxidative stress.

Glutathione — An antioxidant included as a supportive ingredient. Topical evidence is less established than for ascorbic acid, and its concentration is not disclosed.

Alpha-Bisabolol — A soothing ingredient that may help reduce irritation and improve skin comfort, useful in a formula containing a high concentration of acidic vitamin C.

Panthenol + Beta-Glucan + Allantoin — Soothing and humectant ingredients that support hydration and skin comfort.

Multiple forms of Hyaluronic Acid — Sodium hyaluronate, hyaluronic acid and several modified or hydrolyzed forms act primarily as humectants, helping bind water in the upper layers of the skin.

Ceramide NP + Hydrogenated Lecithin — Barrier-supporting lipids that complement the hydrating ingredients, although they occur relatively low in the INCI.

Niacinamide — Supports barrier function and more even-looking skin tone, but it appears very low in the ingredient list and should not be considered a major niacinamide treatment in this serum.

Sodium Ascorbyl Phosphate — A vitamin C derivative included in addition to pure ascorbic acid. It appears lower in the INCI and is best considered a secondary supportive antioxidant.

Adenosine — A skin-conditioning ingredient commonly used in Korean skincare to support a smoother-looking complexion.

Essential Oils + Fragrance Allergens — Orange flower, litsea cubeba, grapefruit, bergamot and spearmint oils are present, together with limonene, linalool and citral. These can be relevant for very sensitive, reactive or fragrance-intolerant skin.
