โ Frequently Asked Questions
Use with caution. The serum contains Tranexamic Acid and Alpha-Arbutin. While topical tranexamic acid is generally considered low-risk (Category B), and niacinamide is safe, there is limited data on topical use during pregnancy. Alpha-arbutin breaks down to hydroquinone, which some sources advise avoiding. Always consult your healthcare provider before use during pregnancy or breastfeeding.
Yes! This serum is fungal acne safe. The formula is free from fatty acids, problematic oils, esters, and polysorbates that feed Malassezia yeast. While it contains Bifida Ferment Lysate, this ingredient is considered safe as it is not lipid-based and doesn't promote yeast growth.
Yes, this serum is generally compatible with most skincare actives. You can use it with AHAs, BHAs, and other Vitamin C products. For retinol, consider alternating nights or using this serum in the AM and retinol in the PM to minimize potential sensitivity. Always introduce new combinations gradually and monitor your skin's response.
This serum works well for all skin types, but is particularly excellent for oily, combination, sensitive, and acne-prone skin. The lightweight, non-greasy formula with EWG Green Grade ingredients makes it ideal for those who find traditional Vitamin C serums too irritating. Dry skin types should follow with a heavier moisturizer.
Most users notice improved hydration and radiance within 1-2 weeks. Visible brightening of overall skin tone typically appears at 2-4 weeks. Significant fading of dark spots and hyperpigmentation usually occurs between 4-8 weeks of consistent use. Clinical studies showed 5.51% improvement in pigmentation in just 10 days. For stubborn pigmentation, continue use for 8-12 weeks.
Apply after cleansing and toning, but before moisturizer and sunscreen. The order is: Cleanser โ Toner โ This Serum โ Moisturizer โ Sunscreen (AM). Apply 2-3 drops to slightly damp skin and pat gently for absorption. Wait 30 seconds before applying your next product.
No, this serum has a comedogenic rating of 1/5 (very low). The lightweight, oil-free formula is non-comedogenic and won't clog pores. It's actually beneficial for acne-prone skin as the niacinamide helps regulate sebum production and minimize pore appearance.
The serum has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. Unlike pure L-ascorbic acid serums that oxidize quickly and turn yellow/brown, this formula uses stable Vitamin C derivatives and Sea Buckthorn Water, which maintain effectiveness longer. The 30ml bottle typically lasts 1-2 months with twice-daily use.
Verdict: Dr. Althea Vitamin C Boosting Serum RENEWED is an excellent choice for anyone seeking effective brightening without the irritation of traditional Vitamin C serums. The 63% Sea Buckthorn Water combined with 5% Niacinamide and 2% Tranexamic Acid creates a powerful yet gentle formula that delivers visible results on dark spots and uneven skin tone. At $23.90, it offers exceptional value compared to prestige alternatives like SkinCeuticals ($115). Ideal for sensitive, acne-prone, and fungal acne-prone skin types. The only drawbacks are the small bottle size and the need for consistent 4-8 week use to see significant results. A must-try K-beauty gem for brightening seekers who prioritize skin compatibility.

โ Frequently Asked Questions
Use with caution. The serum contains Tranexamic Acid and Alpha-Arbutin. While topical tranexamic acid is generally considered low-risk (Category B), and niacinamide is safe, there is limited data on topical use during pregnancy. Alpha-arbutin breaks down to hydroquinone, which some sources advise avoiding. Always consult your healthcare provider before use during pregnancy or breastfeeding.
Yes! This serum is fungal acne safe. The formula is free from fatty acids, problematic oils, esters, and polysorbates that feed Malassezia yeast. While it contains Bifida Ferment Lysate, this ingredient is considered safe as it is not lipid-based and doesn't promote yeast growth.
Yes, this serum is generally compatible with most skincare actives. You can use it with AHAs, BHAs, and other Vitamin C products. For retinol, consider alternating nights or using this serum in the AM and retinol in the PM to minimize potential sensitivity. Always introduce new combinations gradually and monitor your skin's response.
This serum works well for all skin types, but is particularly excellent for oily, combination, sensitive, and acne-prone skin. The lightweight, non-greasy formula with EWG Green Grade ingredients makes it ideal for those who find traditional Vitamin C serums too irritating. Dry skin types should follow with a heavier moisturizer.
Most users notice improved hydration and radiance within 1-2 weeks. Visible brightening of overall skin tone typically appears at 2-4 weeks. Significant fading of dark spots and hyperpigmentation usually occurs between 4-8 weeks of consistent use. Clinical studies showed 5.51% improvement in pigmentation in just 10 days. For stubborn pigmentation, continue use for 8-12 weeks.
Apply after cleansing and toning, but before moisturizer and sunscreen. The order is: Cleanser โ Toner โ This Serum โ Moisturizer โ Sunscreen (AM). Apply 2-3 drops to slightly damp skin and pat gently for absorption. Wait 30 seconds before applying your next product.
No, this serum has a comedogenic rating of 1/5 (very low). The lightweight, oil-free formula is non-comedogenic and won't clog pores. It's actually beneficial for acne-prone skin as the niacinamide helps regulate sebum production and minimize pore appearance.
The serum has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. Unlike pure L-ascorbic acid serums that oxidize quickly and turn yellow/brown, this formula uses stable Vitamin C derivatives and Sea Buckthorn Water, which maintain effectiveness longer. The 30ml bottle typically lasts 1-2 months with twice-daily use.
Verdict: Dr. Althea Vitamin C Boosting Serum RENEWED is an excellent choice for anyone seeking effective brightening without the irritation of traditional Vitamin C serums. The 63% Sea Buckthorn Water combined with 5% Niacinamide and 2% Tranexamic Acid creates a powerful yet gentle formula that delivers visible results on dark spots and uneven skin tone. At $23.90, it offers exceptional value compared to prestige alternatives like SkinCeuticals ($115). Ideal for sensitive, acne-prone, and fungal acne-prone skin types. The only drawbacks are the small bottle size and the need for consistent 4-8 week use to see significant results. A must-try K-beauty gem for brightening seekers who prioritize skin compatibility.
