I love the quality and brightening benefits of this Vitamin C serum, even though it leaves a sticky finish after drying. The sticky residue makes makeup application difficult and limits my red light therapy use, so I prefer applying it at night for optimaProduct Detail

I Love This Sticky Vitamin C Serum for Glowing Skin

I enjoy the quality of this product for skin care and all the benefits. The only thing about it is it’s sticky once it’s dried. I can’t really wear makeup on the days I decide to use this, or I use it at night instead. Because of the stickiness I can’t use my red light stick with it for too long because it doesn’t slide across my face after it starts to dry.

Understanding Vitamin C Serums: Key Ingredients, pH, and Usage Tips

Vitamin C serums, especially formulas containing 15% L‑Ascorbic Acid (the purest and most active form), offer powerful antioxidant protection. In this product, the combination of 15% L‑Ascorbic Acid, Ferulic Acid, and Vitamin E works synergistically to neutralize free radicals, support the skin barrier, and visibly reduce signs of aging like fine lines, dark spots, and sun damage.

The product is formulated with a pH below 4, which scientific studies show is essential for effective absorption into the skin. Serums with a pH above 4 are less effective because the Vitamin C cannot penetrate the skin deeply. This pH‑optimized formula ensures maximum efficacy, making it comparable to premium dermatologist‑approved serums that cost far more.

Customer reviews highlight that while the serum delivers noticeable brightening and an improved complexion, it leaves a sticky residue after drying. This stickiness can interfere with makeup application and the smooth gliding of devices like red light therapy sticks. To avoid this, many users, including the reviewer, switch to nighttime use. Nighttime application allows the serum to absorb without competing with makeup or other tools, and it still provides all the antioxidant, anti‑aging benefits while you sleep.

For best results, apply 2–3 drops to a clean, dry face after cleansing and before moisturizer. If stickiness is a concern, wait for the serum to fully absorb (3–5 minutes) before applying additional products. The 30‑day satisfaction guarantee allows you to test if this routine works for your skin.

Ingredients like Ferulic Acid (which has a light medicinal scent) and Vitamin E enhance stability and efficacy. The serum is non‑greasy when absorbed, but some users with sensitive or oily skin may notice the sticky texture. Applying a lightweight moisturizer on top can help reduce the sticky feel while locking in hydration.
