“Morning C, Night A” is a skincare routine method that refers to “Using Vitamin C derivative skincare products in the morning; while Vitamin A skincare products at night.” Vitamin C and Vitamin A have long been star ingredients in the skincare industry, and the combination of C+A allows the skincare effects of the two ingredients to complement each other, achieving better anti-aging and brightening results.

Morning C：During the daytime, applying Vitamin C derivative skincare products can effectively fight oxidation, brighten skin tone, and reduce dark spots. This is because Vitamin C helps protect the skin from free radical damage caused by UV rays and environmental pollution during the day.

Night A： In the evening, using Vitamin A derivative skincare products is recommended. Vitamin A and its derivatives are considered as the essentials for anti-aging.

Retinol is a derivative of Vitamin A – much gentler than Retinoic Acid. Retinol can accelerate cell regeneration, making skin firmer and plumper.

Step 1: Cleanse Your Skin

Start with a gentle cleanser. Avoid using exfoliants, deep-cleansing products, or anything containing strong acids at the same time. This prevents over-stimulation and protects your skin's natural balance.

Step 2: Tone and Soothe

Apply an alcohol-free, hydrating toner with a clean cotton pad. This soothes and balances your skin, prepping it for moisturizing without over-drying.

Skin Types Requiring Caution:

Sensitive Skin: Vitamin C and A are potent ingredients that may cause irritation. Those with sensitive skin should always perform a patch test before incorporating these ingredients into their skincare routine. Apply a small amount to the inner elbow or wrist and observe for any adverse reactions. Start with low concentrations and gradually increase as tolerated.

Dry Skin: Vitamin A can cause dryness and peeling. Individuals with dry skin should prioritize hydration when using Vitamin A products and monitor their skin closely. Discontinue or reduce usage if excessive dryness or peeling occurs.

Pregnant or Breastfeeding Women: Pregnant and breastfeeding women should avoid high concentrations of Vitamin A. Consult a doctor before using any new skincare products during pregnancy or while breastfeeding.

Tips:

THE KIEHL'S PATCH TEST™：

• Apply a small amount of the product to the inner elbow or wrist.
• Observe the area for any reactions. If you experience any irritation such as a rash, burning, stinging, or redness, the product is not suitable for you.
• If no adverse reactions occur, apply a small amount of the product to a small area of the face or body.
• Observe the area for one to two days. If no irritation develops, the product is likely suitable for regular use.

Don't Overdo It: Avoid layering too many active ingredients which can overwhelm the skin and cause irritation. Separate use of BHAs/AHAs and Vitamins A/C is recommended. Simplify your routine, choosing products suited to your skin type.

Start Low and Go Slow: Start with low concentrations of both Vitamin C and A to allow your skin to adjust and minimize irritation. Vitamin A, in particular, may initially cause redness or peeling. This is usually normal and can be managed by reducing frequency or concentration until your skin adapts.

Watch Your Skin: Monitor your skin closely when introducing any new product. Dryness and peeling are common for any skin types as skin adjusts to Vitamin A. Use a hydrating serum (like hyaluronic acid) and moisturizer to prevent moisture loss. Stop using and consult a dermatologist if you experience irritations or allergic reactions.

Sunscreen is Key: Always apply sunscreen (at least SPF 30) after morning Vitamin C application. This helps prevent dark spots as Vitamin C and A can increase sun sensitivity. Daily sunscreen is crucial for protection against sun damage, even on cloudy days. If sun exposure is too high, may consider skipping Vitamin C in the morning.
