Lovi Assistant explains
- Offers moderate brightening and smoothing for your oily skin due to ascorbic acid and ferulic acid, which provide antioxidant benefits and help even skin tone.
- The presence of Vitamin E and panthenol offers general skincare benefits like hydration and antioxidant protection, which are supportive for oily shine.
- The formula is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing Bisabolol.
How to apply
- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

Questions and answers
How well does Paula's Choice C15 Super Booster work for oily skin?

Ascorbic acid and ferulic acid help brighten and smooth your oily skin, while vitamin E and panthenol provide hydration and antioxidant protection to support oily shine. Oily skin often benefits even more from ingredients like niacinamide and zinc PCA to control excess oil and manage pores.

What does Ferulic Acid do for oily skin?
Ferulic acid helps protect oily skin from sun damage and environmental stress when used as part of a daytime antioxidant serum. It is often combined with vitamins C and E to boost overall defense and keep skin healthy.

To get a better fit for oily skin, a product of this type needs lightweight hydration and ingredients that control shine while delivering antioxidants without heaviness.
