What exactly is Dr. Althea Gentle Vitamin C Serum, and why is it so popular?
Dr. Althea Gentle Vitamin C Serum is a lightweight, beginner-friendly serum specifically formulated to brighten your skin, fade dark spots, and improve overall skin tone. Its popularity comes from its gentle yet effective ingredients like Niacinamide, Sea Buckthorn Extract, and Green Tea, making it suitable even for sensitive or acne-prone skin.
What does the name "Gentle Vitamin C Serum" signify?
The name highlights the serum’s mild yet effective formulation. Unlike many Vitamin C products that can cause irritation, this serum gently delivers brightening benefits, ideal for sensitive skin.
Will this serum work for my specific skin concerns?
Absolutely! Dr. Althea Gentle Vitamin C Serum is designed to address dullness, dark spots, uneven skin tone, or early signs of aging. Its soothing ingredients also make it suitable for sensitive, reactive, or acne-prone skin types.
How quickly will I see results?
Most customers notice brighter, more radiant skin within 2 to 4 weeks of regular use. Significant improvements in dark spots and evenness typically occur around 6 to 8 weeks. Consistent daily use along with sunscreen is recommended for optimal results.
What makes this serum different from competitors?
Dr. Althea’s formula uses natural Sea Buckthorn Extract combined with Niacinamide, offering gentle brightening without irritation. Its oil-capsule delivery system ensures deep hydration, fast absorption, and a comfortable, non-sticky feel, distinguishing it from other Vitamin C serums.
How frequently should I apply it?
For best results, apply this serum daily in the morning after cleansing and toning. Massage a few drops gently into your skin, followed by a moisturizer and sunscreen.
Why should I trust this over other brands or pricier options?
Dr. Althea combines scientifically-backed ingredients with gentle formulations tailored specifically for sensitive skin. With carefully selected ingredients and Korean skincare expertise, the serum delivers premium-quality results without the premium price.

4 REASONS WHY
Thousands Are Switching from Harsh Vitamin C Serums to Gentle Vitamin C Serum:

Brightens Sensitive Skin Without Irritation
This serum features a stable, gentle form of vitamin C (3-O-Ethyl Ascorbic Acid) combined with calming Green Tea and Allantoin, effectively brightening dull complexions without triggering redness or discomfort common in harsher serums.
Fades Dark Spots & Acne Marks
Powered by Niacinamide (Vitamin B3) and potent Sea Buckthorn Extract, it specifically targets stubborn hyperpigmentation, evening out your skin tone faster and more effectively than conventional serums, which often lack this powerful combination.
Hydrates & Balances Skin
Thanks to its innovative oil-capsule system, this serum quickly penetrates deep into your skin, delivering lasting hydration and maintaining optimal moisture levels. Unlike traditional sticky serums, it absorbs instantly, leaving your skin refreshed, smooth, and comfortable.
Calms & Protects Acne-Prone Skin
Uniquely formulated with soothing ingredients like Allantoin and Green Tea, this serum gently calms irritation and redness associated with acne flare-ups. Its acne-safe formula strengthens your skin’s natural barrier, reducing breakouts and leaving skin visibly healthier and clearer.
