A powerful and efficient brightening formula, Dr Althea vitamin c boosting serum gradually reduces the appearance of hyperpigmentation while enhancing overall skin radiance. This advanced vitamin C treatment helps improve dull and uneven skin tone with consistent use. However, if you have extremely sensitive skin, I would suggest using the Dr. Althea Gentle Vitamin C Serum instead. For beginners or those with reactive skin, that milder version may be a better starting point.

Formulated with Centella Asiatica and eight different forms of hyaluronic acid, Dr Althea vitamin c boosting serum helps soothe irritation while delivering deep hydration. The lightweight gel-based texture absorbs quickly into the skin without leaving a sticky or greasy residue. After application, the skin appears brighter, smoother, and more supple.

Because this serum works to brighten the complexion and reduce hyperpigmentation, applying a high-SPF sunscreen during the day is essential. I personally avoid layering vitamin C with retinol or retinoid serums in the same routine, as the combination can be too strong for my occasionally sensitive skin. Before adding products like Dr Althea vitamin c boosting serum to your routine, it’s always wise to consult a dermatologist, especially if you have skin concerns such as unusual moles or persistent sensitivity.

This high-potency brightening formula contains 63% Hippophae Rhamnoides Water and 5% Niacinamide to target dullness and uneven pigmentation. With regular use, Dr Althea vitamin c boosting serum helps promote a clearer, more luminous complexion in as little as two weeks.

Gently tap the serum into the skin with your fingertips to enhance absorption.
