How does the Skin Cycling method work?

Skin Cycling is a clinical method of rotating nighttime active treatments. It alternates nights of active stimulation (gentle chemical exfoliation and retinoids) with dedicated barrier recovery nights (3:1:1 ceramides, centella, panthenol). This prevents retinoid dermatitis while maximizing collagen synthesis.

What is the correct clinical dosage for SPF 50+?

To achieve the certified label protection, apply 0.04–0.05 fl oz (1.25 ml / approx. 1/4 teaspoon) across your face and neck. A reliable practical measure is the "two-finger rule": two full lines of sunscreen dispensed along your index and middle fingers.

What is the best approach for couperose and rosacea-prone skin?

Avoid hot water, facial steamers, abrasive scrubs, and drying alcohols. Introduce 10% azelaic acid and centella asiatica to soothe micro-vessels, and use 100% mineral sunscreen (Zinc Oxide) that bounces rays without generating trapped dermal heat.

Is this a prescription medical treatment plan?

No. This tool generates cosmetic skincare protocols based on peer-reviewed dermatology literature. Severe skin conditions (cystic acne, severe rosacea flare-ups) require direct consultation with a board-certified dermatologist.
