Bioglossy Retinol Serum 2.5% Night Treatment, 30 ml — Time-release Retinol with Squalane & Hyaluronic Acid

Bioglossy Retinol Serum 2.5% is a time-release nighttime treatment that resurfaces skin while delivering hydration and antioxidant support for a visibly smoother, more even complexion.

This lightweight evening serum combines a sustained-release 2.5% pure retinol with nourishing hydrators and antioxidants to address fine lines, uneven texture and early sun-related discoloration without overwhelming sensitive skin. The formula blends squalane, hyaluronic acid and niacinamide with vitamins C and E for moisture, barrier support and antioxidant defense. Fragrance-free and designed for gradual introduction, it aims to improve skin’s look overnight while you sleep.

How does Bioglossy Retinol Serum improve skin texture?

The sustained-release retinol works continuously through the night to encourage surface renewal, helping smooth rough patches and minimize the look of fine lines over repeated use. Complementary humectants and emollients keep skin comfortable during the renewal process, reducing the risk of dryness.

• 2.5% time-released pure retinol for continuous overnight action
• Hyaluronic acid attracts and holds moisture for plumper-feeling skin
• Squalane softens and reduces dryness during retinol activity
• Niacinamide promotes even tone while supporting the skin barrier

Will this serum cause irritation on sensitive skin?

The formula is crafted for gradual use and includes hydrating, barrier-supporting ingredients to minimize irritation risk. Users are advised to begin with alternate-night application and increase frequency as tolerance builds, which helps sensitive skin acclimate safely.

• Start every other night, then move to nightly as tolerated
• Hydrating base of squalane and hyaluronic acid soothes during use
• Niacinamide and vitamins C and E provide supportive antioxidant care
• Fragrance-free to reduce potential irritation triggers

How should I layer this serum into my evening routine?

Apply to clean, dry skin after cleansing and any water-based toners, then follow with a moisturizer to lock in hydration. Because retinol increases sun sensitivity, use sun protection daily and limit daytime sun exposure while using the serum.

• Shake bottle, then dispense a few drops onto fingertips
• Pat gently over face and neck, avoiding eyes and lips
• Follow with moisturizer; use SPF each morning
• Adjust frequency if mild redness or dryness appears

What additional benefits do the vitamins and hydrators provide?

Vitamins C and E act as antioxidant partners that help protect against environmental stressors and support an even-looking tone, while niacinamide helps visibly smooth and brighten. Together with squalane and hyaluronic acid, they ensure the retinol’s resurfacing action doesn’t leave skin feeling tight or flaky.

• Vitamin C + E: antioxidant support and radiance assistance
• Niacinamide (B3): helps reduce the appearance of uneven tone and supports barrier health
• Hyaluronic acid: boosts surface hydration for a plumper look
• Squalane: lightweight lipid that replenishes softness

Who is this for: Bioglossy Retinol Serum 2.5% is made for adults seeking a robust, nightly retinol treatment that balances potent renewal with hydration. It suits people who want to address early signs of aging, texture concerns, and uneven tone while using a fragrance-free formula designed for gradual introduction. Not recommended for pregnant or breastfeeding users; consult a healthcare professional if uncertain. For best results, pair with daytime SPF and introduce the serum slowly into your routine.
