Key Ingredients and Benefits
The Think Bright Glow + Hydrate Serum boasts a powerful combination of vitamin C (ascorbic acid) and hyaluronic acid. Vitamin C is a well-known antioxidant that helps protect the skin from environmental damage, brightens dark spots, and promotes collagen production. Hyaluronic acid, on the other hand, is a humectant that draws moisture into the skin, plumping fine lines and leaving a dewy finish. Together, they target dullness and dehydration, two common skin concerns.
LYS Beauty also includes squalane and niacinamide in the formula, which further support hydration and barrier repair. The serum is fragrance-free and suitable for sensitive skin types. The brand emphasizes clean ingredients, and this serum is no exception—free from parabens, sulfates, and phthalates.
- Vitamin C: brightens and evens skin tone
- Hyaluronic Acid: deeply hydrates and plumps
- Squalane: locks in moisture without greasiness
- Niacinamide: soothes and improves texture
Texture and Application
The serum has a lightweight, slightly viscous texture that glides onto the skin smoothly. It absorbs quickly without any sticky residue, making it ideal for layering under moisturizer and makeup. A few drops are enough to cover the face and neck. For best results, apply it to clean, damp skin morning and evening. The pump bottle is hygienic and allows for easy dispensing.
Users with oily or combination skin will appreciate the non-greasy feel, while dry skin types may want to follow with a richer moisturizer. The serum layers well with other products, including the Confident Complexion Makeup Sponge for seamless foundation application.
- Use 2-3 drops for full coverage
- Apply before moisturizer and sunscreen
- Can be mixed with a facial oil for extra hydration
Performance and Results
After consistent use over several weeks, many users report a noticeable improvement in skin brightness and overall radiance. Dark spots from sun damage or acne scars begin to fade, and the skin looks more even. The hyaluronic acid provides immediate hydration, leaving the skin plump and smooth. The serum also helps makeup apply more evenly and stay fresh longer.
It's worth noting that vitamin C can be unstable, but LYS uses a stabilized form to maintain efficacy. The serum has a subtle, natural scent from the ingredients, but no added fragrance. For those with sensitive skin, it's gentle enough for daily use without irritation.
- Visible brightening in 2-4 weeks
- Instant hydration boost
- Suitable for all skin types, including sensitive
How to Incorporate into Your Routine
For optimal results, use the Think Bright Glow + Hydrate Serum as part of your morning and evening skincare routine. After cleansing and toning, apply the serum to damp skin. Follow with a moisturizer and sunscreen during the day. At night, you can layer it with a night cream or facial oil. The serum also pairs well with other LYS products like the Aim High Highlighter Stick for an extra glow on cheekbones.
If you're new to vitamin C, start by using it every other day to allow your skin to adjust. Over time, you can increase to twice daily. Remember to store the serum in a cool, dark place to preserve its potency.
- Morning: Cleanse, Tone, Serum, Moisturizer, Sunscreen
- Evening: Cleanse, Tone, Serum, Night Cream
- Store away from direct sunlight
