How quickly will I notice brighter skin?

Many users see an immediate boost in skin luminosity within minutes due to the potent 15% L‑ascorbic acid concentration and a formula designed for rapid absorption. Continued nightly or morning use typically improves overall brightness and evens tone over several weeks.

• 15% pure L‑ascorbic acid for quick brightening effects.
• Fast‑absorbing serum texture that layers under moisturizers and sunscreen.
• Visible glow often noticed within 15 minutes of application.
• Consistent use supports gradual reduction in discoloration.

Will this serum irritate sensitive or reactive skin?

The formula is crafted to minimize irritation while delivering high‑strength Vitamin C; it contains supportive antioxidants like ferulic acid and ergothioneine that help stabilize and soothe the active. If you have very reactive skin, start with a patch test or use every other day until tolerance builds.

• Includes ferulic acid to bolster antioxidant stability.
• Ergothioneine supports skin protection from oxidative stress.
• Suitable for many sensitive skin types when introduced gradually.
• Patch testing recommended for highly reactive skin.

How should I add the BOOST C15 Super Booster to my routine?

Apply a few drops to clean, dry skin after cleansing and before heavier treatments or moisturizer; it can be used in the morning or evening. When used in the morning, follow with a broad‑spectrum sunscreen to protect newly brightened skin from UV exposure.

• Apply on cleansed, dry skin—few drops are sufficient.
• Layer under moisturizers and sunscreens for daytime use.
• Can be combined with most serums but avoid mixing with unstable actives at once.
• Store away from direct light and heat to preserve potency.

What performance benefits can I expect besides brightness?

Beyond instant radiance, the booster supports the appearance of smoother skin and helps reduce the look of fine lines and uneven texture with continued use. Antioxidant partners enhance defense against environmental stressors that can accelerate visible aging.

• Improves the look of fine lines and surface texture.
• Promotes a more even skin tone with consistent application.
• Antioxidant blend helps protect against environmental damage.
• Light, non‑greasy finish makes it easy to layer under other products.

Who this product is for: Paula's Choice BOOST C15 Super Booster suits anyone wanting a high‑strength Vitamin C treatment that quickly increases radiance and supports smoother, more even‑looking skin. It is especially useful for people concerned with early signs of aging, dullness, or discoloration who prefer a concentrated, easily layered serum. If you have very sensitive or reactive skin, introduce it gradually and consult patch testing recommendations before full face application.
