Questions and answers
How well does Dr. Alethea Vitamin C Serum work for acne-prone skin?
Dr. Alethea Gentle Vitamin C Serum works moderately well for acne-prone skin, as its ingredients help control oil and soothe blemishes while providing antioxidants. However, products that fit this skin type better need ingredients like propolis or zinc PCA alongside niacinamide to deliver optimal hydration and balance without excess oiliness.
Which ingredients make this serum a good fit for acne-prone skin?
The ingredients that make this serum work for acne-prone skin are 3-0-Ethyl Ascorbic Acid and niacinamide, which help control oil, alongside allantoin and green tea water that calm blemishes. To work even better for this skin type, a product needs soothing ingredients like propolis or zinc pca that provide extra blemish care and hydration without extra oiliness.
What does Niacinamide do for acne-prone skin?
Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
What does 3-O-Ethyl Ascorbic Acid do for acne-prone skin?
3-O-Ethyl Ascorbic Acid helps calm acne-prone skin by reducing inflammation and protecting skin cells from oxidative stress. It is unlikely to irritate when used as part of your daily routine.
Where does this serum go in a skincare routine for acne-prone skin?
This treatment goes in the evening routine after cleansing and before moisturizing, though some serums may also be used in the morning or twice a day. For acne-prone skin, an average fit product needs soothing ingredients like allantoin and antioxidants like niacinamide to help calm blemishes and manage oil production.

Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but it works best to apply retinol at night and this vitamin C serum in the morning to avoid overloading your skin. This product helps calm and brighten, but acne-prone skin often needs a treatment with stronger oil-controlling and pore-clearing ingredients like salicylic acid or benzoyl peroxide for better results.
How often should I use this serum?
You can use this treatment in your evening routine, applying it after cleansing and before moisturizing. This serum works for your skin, though an acne-prone skin type needs gentle ingredients like niacinamide and soothing plant extracts to help control oil and calm blemishes without irritation.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
This serum is unlikely to cause breakouts on acne-prone skin, as it contains soothing ingredients like Allantoin and Camellia Sinensis Leaf Water, though it is only an average fit for your skin. Acne-prone skin needs a product that includes targeted oil-control ingredients and calming plant extracts to keep pores clear and calm.
