Dr. Althea Gentle Vitamin C Serum 30 ml

Dr.Althea Gentle Vitamin C Serum 30 ml is a lightweight Korean brightening serum developed for dullness, uneven-looking skin tone, and the appearance of dark spots. Its gentle formula combines 20% Sea Buckthorn Fruit Water, 5% Niacinamide, 2% Green Tea Leaf Water and the Vitamin C derivative 3-O-Ethyl Ascorbic Acid.

The watery serum spreads easily and absorbs without an excessively heavy or sticky finish. It is particularly relevant for first-time Vitamin C users and sensitive-looking skin that requires gradual brightening care alongside hydration and soothing support.

Important: The 20% claim refers to Hippophae Rhamnoides or Sea Buckthorn Fruit Water—not 20% pure Vitamin C. The manufacturer does not disclose the percentage of 3-O-Ethyl Ascorbic Acid in the current official formula.

Dr.Althea Gentle Vitamin C Serum Overview

Dr.Althea Gentle Vitamin C Serum is designed to provide brightening care without relying on a high disclosed concentration of pure Ascorbic Acid. Instead, the formula uses Sea Buckthorn Fruit Water alongside 3-O-Ethyl Ascorbic Acid, Niacinamide and supportive soothing ingredients.

This combination helps improve the appearance of dullness, uneven tone and post-blemish marks while supporting a hydrated and comfortable skin feel. The brand particularly recommends the Gentle version for beginners, sensitive-looking skin and people who prefer gradual daily Vitamin C care.

Dr.Althea also sells a separate Vitamin C Boosting Serum. The product described here is the green-bottle Gentle Vitamin C Serum with 20% Sea Buckthorn Fruit Water; it should not be confused with the higher-intensity Boosting Serum.

Key Ingredients and Their Functions

20% Sea Buckthorn Fruit Water

Hippophae Rhamnoides Fruit Water, commonly known as Sea Buckthorn or Vitamin Tree Fruit Water, makes up 200,000 ppm or 20% of the current formula. It provides antioxidant and moisture-supporting care and contributes to a brighter, healthier-looking complexion.

This percentage must not be interpreted as 20% pure Vitamin C. Sea Buckthorn Fruit Water is a botanical ingredient, while the formula’s separately listed Vitamin C derivative is 3-O-Ethyl Ascorbic Acid.

5% Niacinamide

Niacinamide is present at 50,000 ppm or 5%. It helps improve the appearance of dullness and uneven tone while supporting the skin barrier and overall skin texture.

3-O-Ethyl Ascorbic Acid

3-O-Ethyl Ascorbic Acid is a Vitamin C derivative used to support antioxidant and brightening care. Its exact concentration is not disclosed in the current official product information, so the serum should not be described as containing 20% Vitamin C.

2% Green Tea Leaf Water

Camellia Sinensis Leaf Water is included at 20,000 ppm or 2%. It supplies antioxidant and skin-comforting support, helping balance a routine focused on pigmentation and dullness.

Allantoin, Bifida Ferment Filtrate and Adenosine

Allantoin helps soothe and comfort the skin. Bifida Ferment Filtrate supports conditioning and hydration, while Adenosine contributes to smoother and healthier-looking skin.

The current official ingredient list also contains Tea Tree Leaf Extract. This is a botanical extract and should not be confused with Tea Tree Essential Oil. Added fragrance, parfum and essential oils do not appear in the current official ingredient list.

Formulations can be updated. Always check the ingredient list printed on the product received before using Dr.Althea Gentle Vitamin C Serum.

Texture and Formula Features

The serum has a lightweight, watery texture that can be applied in thin layers. It absorbs comfortably and is designed to provide hydration without leaving an excessively greasy or sticky residue.

Dr.Althea describes the formula as using a vitamin-oil capsule system. The small capsules disperse as the serum is spread, supporting a smooth application experience.

The current formula contains 19 listed ingredients and is presented by the brand as vegan-certified. Dr.Althea also states that the product has completed a skin-irritation test. These features do not guarantee compatibility for every individual, particularly if the skin is highly reactive.

Brand-Published Test Results

In brand-published 14-day testing, the serum reportedly produced a 2.45% reduction in a measured pigmentation or melanin-area parameter and a 1.21% improvement in an overall dull-skin-tone measurement.

The brand also reports that 100% of participants in its evaluation expressed satisfaction with overall use, spreadability, brightening and moisturization. These are manufacturer-published test and survey results rather than guaranteed outcomes. Individual results can vary according to skin condition, routine and consistency of use.

Which Skin Types Can Use It?

Dr.Althea Gentle Vitamin C Serum may be considered for:

• Normal skin
• Dry or dehydrated-looking skin
• Combination skin
• Oily but dehydrated skin
• Dull or uneven-looking skin
• Skin with visible post-blemish marks
• Sensitive-looking skin requiring gradual brightening care
• First-time Vitamin C serum users

Although it is positioned as a gentle serum, Vitamin C derivatives, Niacinamide and botanical extracts may still cause sensitivity in some users. Patch testing and gradual introduction are recommended.

How to Use Dr.Althea Gentle Vitamin C Serum

1. Cleanse the face using a suitable cleanser.
2. Apply toner if it is part of your routine.
3. Dispense one or two drops of serum.
4. Spread a thin, even layer over the face and neck.
5. Gently pat until absorbed.
6. Follow with a suitable moisturizer.
7. Apply broad-spectrum sunscreen during the daytime.

New Vitamin C users may begin once daily or every other day. Increase the frequency gradually if the skin remains comfortable. Avoid applying an excessive amount, as more product does not necessarily produce faster results.

Recommended Skincare Routine

Morning: Cleanser → Toner → Dr.Althea Gentle Vitamin C Serum → Moisturizer → Broad-Spectrum Sunscreen

Evening: Cleanser → Toner → Dr.Althea Gentle Vitamin C Serum → Moisturizer

Consistent daytime sun protection is important when a routine focuses on visible pigmentation or uneven tone. This serum provides skincare support but does not replace sunscreen.

Layering with Other Active Ingredients

The serum may be layered with simple hydrating products containing ingredients such as Hyaluronic Acid, Panthenol, Ceramides or Centella. Apply products from the lightest to the richest texture.

If the routine already contains retinoids, strong exfoliating acids or Benzoyl Peroxide, introduce the serum gradually. Sensitive or inexperienced users may use potentially irritating actives in separate routines or on alternate days rather than applying everything together.
