Cosmedix Reboot Overnight Hydration Complex 30ml

Description
Probiotic night serum for balance and hydration during sleep
During sleep, the skin goes through its most active repair phase. Circulation changes, body temperature rises slightly, and the processes for cell renewal, collagen production, and barrier repair work at their strongest — a biological window too valuable to waste. At the same time, this is when the skin loses the most moisture through transepidermal water loss, making waking up with dull, marked skin a common complaint.
Cosmedix Reboot is a lightweight night serum specifically formulated for this window. The formula combines probiotic ingredients (Lactobacillus and coconut extract) with a hydrating carbohydrate complex and the peptide palmitoyl tripeptide-5. Together they work on moisture, balance, and repair — without the heavy texture of a classic night cream. The skin is noticeably smoother, plumper, and more balanced in the morning, even for sensitive skin types.
Benefits
- Hydrates and balances the skin throughout the night
- Strengthens the skin barrier with probiotic action
- Reduces the appearance of fine lines with peptides
- Soothes sensitive and irritated skin with aloe vera
- Lightweight texture that absorbs quickly without leaving pillow marks
Active ingredients
Lactobacillus and coconut extract: A probiotic duo that supports the healthy bacterial balance on the skin. The skin microbiome forms the first line of defense against impurities, irritation, and environmental damage — and often becomes unbalanced due to over-cleansing, retinol use, or stress. Reboot actively restores this balance overnight, resulting in more resilient, balanced skin.
Saccharide Isomerate: A carbohydrate complex that provides both immediate and long-lasting hydration. Unlike classic humectants, saccharide isomerate specifically binds to structures in the skin, allowing it to continue working even after washing — a clinically proven 72-hour hydration effect.
Palmitoyl Tripeptide-5: A targeted peptide that supports the skin’s natural collagen production. Reduces the appearance of fine lines and contributes to firmer-looking skin. Works synergistically with the probiotic ingredients — a healthy microbiome is essential for optimal peptide response.
Aloe vera (Aloe Barbadensis Leaf Juice): A classic soothing ingredient that calms and hydrates the skin. Especially valuable for sensitive skin and for those using retinol or acids in the evening — Reboot can then be applied as a soothing layer on top.
Glycerine: A natural humectant that draws water from the environment and deeper skin layers to the surface. Enhances the immediate moisturizing effect and keeps the skin nourished throughout the night.
Lactobacillus Ferment: A fermented ingredient that enhances the probiotic profile of Reboot. Helps restore the skin barrier and contributes to smoother, more resilient skin with long-term use.

Frequently Asked Questions
Can I combine Reboot with retinol products like Serum 16 or Define?
Yes, it is an excellent addition especially then. First apply the retinol serum, let it dry for a few minutes, then apply Reboot on top. The probiotic and hydrating effects soothe possible retinol sensitivity and help keep the skin barrier intact during active treatment. A classic routine many users follow.
Does Reboot also work for oily or combination skin?
Definitely. The lightweight, oil-free texture makes Reboot excellent for oily or combination skin that wants hydration without the heaviness of a cream. The probiotic action also supports the skin’s natural balance, which helps regulate sebum levels especially in oily skin.
Can I use Reboot during the day as well?
The product is primarily formulated for the evening, when the skin goes through its natural repair window. However, it can also be used during the day as a hydration boost under a day cream and SPF — especially valuable with dry air conditioning or dehydrated skin on a busy workday.
What is the difference between Reboot and Surge?
Both hydrate, but work through different mechanisms. Surge is a hyaluronic acid booster that delivers moisture directly to the skin. Reboot works on the microbiome and skin barrier with probiotics and peptides for long-term structural balance. Many users combine both in the same routine: Surge first for immediate hydration, then Reboot for barrier support.
Is Reboot suitable during pregnancy and breastfeeding?
Yes. The formula contains no retinoids, salicylic acid, or other ingredients that are discouraged during these periods. Reboot is a safe choice for those looking for an effective hydrating serum during pregnancy or breastfeeding without concerns.
How long does a 30ml bottle last?
With daily evening use, a bottle usually lasts two to three months. Those who use Reboot both morning and evening get one to one and a half months. The bottle has an airless pump that keeps the serum fresh until the last drop.
