Apply 3-4 pumps onto face, neck, and chest morning + night. If you’re new to vitamin C, leveling up the strength of your vitamin C, or if you have sensitive skin, patch test on the inner forearm or side of the neck first. Start using once a day in the morning before working your way up to twice a day, and layering with other skincare actives.

Skin Cycling

Asta C™ Vitamin C Age Defense Serum is not part of the evening Skin Cycling Program, but can be integrated into any AM or PM routine.

Skin Cycling is a strategic, customizable program, created by Dr. Bowe, for cycling through your evening skincare to maximize results, while minimizing irritation. Skin Cycling takes a streamlined, “less is more” approach to skincare, making your products work smarter, harder, and better for you. With 3.5 billion TikTok views, the viral program has influenced skincare worldwide.

Below is the Classic Skin Cycling Program, which can be customized by adding more Retinal Nights or Recovery Nights depending on your skin's needs.

Night 1: Exfoliation Night

Dr. Bowe opts for chemical exfoliating products over harsh and gritty scrubs. A chemical exfoliating serum can give your skin an immediate glow, prepping you to get the most out of night 2. Exfoliation Night™ Resurfacing + Brightening Serum is specifically formulated to push your skin outside its comfort zone, driving clinically-proven results on night 1 of your Skin Cycling Program, without harming the delicate skin barrier.

Night 2: Retinoid Night

Retinoids are one of the powerful ingredients to include in your Skin Cycling Program. They work to improve skin by breaking down dead skin cells and generating new skin cells—firming and smoothing the look of skin. Your skin’s sensitivity may influence the strength of the retinoid you choose, as some people can tolerate a retinoid more frequently than others. Retinal is the most powerful retinoid you can get without a prescription. Due to Dr. Bowe's expert formulation of Retinal Night™ Advanced 0.1% Retinal Firming Treatment, it's proven to be highly-potent and stable, yet also clinically-proven to be well-tolerated by skin. This makes Retinal Night™ perfect for leveling up any Skin Cycling Program.

Night 3 + 4: Recovery Nights

Hold off on exfoliating acids and retinoids and give your skin a chance to recover. On Recovery Nights, you want to focus on nourishing your skin microbiome and repairing your skin barrier—think hydration and moisture. Dr. Bowe developed Bowe Glowe™ Microbiome Nourishing Cream for every morning, then each night of your Skin Cycling Program, but especially for Recovery Nights to give your skin the hydration and barrier repair it needs. It has been clinically-proven to help repair the skin barrier in just one hour!*

*Independent clinical study of 20 subjects using Bowe Glowe. Subjects were evaluated for transepidermal water loss (TEWL) at the 1 hour time point (Tewameter®).
