ALASTIN’s Renewal Retinol, C-RADICAL Vitamin C Serum, and Restorative Skin Complex are premium anti-aging treatments designed to work together: retinol for renewal, vitamin C for antioxidant protection and brightness, and peptides for firmness and elasticity. The NYK Fashion City listings appear to be reseller pages for these ALASTIN products, though the product pages could not be directly retrieved for their listed prices.

At a glance

Renewal Retinol

ALASTIN Renewal Retinol is a nighttime anti-aging serum intended to smooth texture, improve tone, and reduce the appearance of fine lines and wrinkles. It is available in 0.25% and 0.5% retinol strengths; ALASTIN recommends 0.25% for beginners and 0.5% for people already accustomed to retinol.

How to use it

• Start with two or three nights per week, then gradually increase to nightly use only if your skin tolerates it.
• Apply one pump to clean, completely dry skin on the face in the evening.
• Avoid the eye area; if product gets into the eyes, rinse thoroughly with water.
• Use a moisturizer afterward if needed, especially during the adjustment period.
• Apply broad-spectrum sunscreen every morning, since retinol can increase sensitivity to sunlight.

Benefits

Retinol supports skin-cell turnover, which can improve rough or uneven texture and soften the look of fine lines over time. ALASTIN’s formula also includes soothing and hydrating ingredients, including oat extract and silver mushroom, intended to reduce irritation and help protect the skin barrier.

Who should use caution

If you are pregnant, breastfeeding, using prescription acne or anti-aging treatments, or have very sensitive skin, check with a dermatologist before starting retinol. Do not combine it with strong exfoliating acids on the same night until you know how your skin responds.

C-RADICAL Vitamin C Serum

C-RADICAL Defense Antioxidant Serum is ALASTIN’s vitamin-C-centered antioxidant serum. It combines a proprietary form of vitamin C with 14 additional antioxidants to help defend against environmental stressors such as UV exposure, pollution, and blue light.

How to use it

• Apply 1–2 pumps to clean, dry facial skin in the morning and evening.
• Allow it to absorb before applying moisturizer.
• In the morning, finish with a broad-spectrum sunscreen; vitamin C complements sunscreen but does not replace it.
• Avoid direct contact with the eyes.

Benefits

The serum is designed to brighten dull skin, refine texture, and reduce the visible appearance of fine lines, wrinkles, photodamage, redness, and brown spots. ALASTIN states that the formula helps reduce free-radical effects in the skin by up to 74%.

This makes it especially useful for people concerned about dullness, uneven pigmentation, sun-related aging, or environmental damage. Its antioxidant approach is protective as well as corrective, so consistency matters more than using a very large amount at once.

Restorative Skin Complex

The Restorative Skin Complex is ALASTIN’s flagship peptide-based anti-aging serum. It uses TriHex Technology to target skin texture, tone, hydration, volume, and elasticity, with an emphasis on skin that shows collagen and elastin depletion.

How to use it

• After cleansing, apply 1–2 pumps to the face—and optionally the neck—morning and evening.
• Let it absorb fully before applying moisturizer.
• During the day, finish with sunscreen.
• It can be layered with vitamin C in the morning and retinol at night; apply Restorative Skin Complex first, then the other serum.

Benefits

This serum is positioned as a comprehensive daily anti-aging treatment. Its intended benefits include smoother fine lines and wrinkles, improved firmness and elasticity, a more hydrated appearance, more even tone, and a fuller-looking complexion.

Because it is gentle enough for twice-daily use, it is often the easiest of the three products to incorporate into a routine. Visible changes in firmness, texture, and tone generally require consistent use over roughly 8–12 weeks rather than overnight results.

How to build a routine

For most people, the most effective and manageable approach is to introduce one active at a time.

Morning

1. Gentle cleanser
2. Restorative Skin Complex, 1–2 pumps
3. C-RADICAL Vitamin C Serum, 1–2 pumps
4. Moisturizer, if needed
5. Broad-spectrum SPF 30 or higher

Evening

1. Gentle cleanser
2. Restorative Skin Complex, 1–2 pumps
3. Renewal Retinol, one pump—starting only 2–3 nights weekly
4. Moisturizer

This layering order follows ALASTIN’s guidance: use the Restorative Skin Complex first, then vitamin C in the morning or retinol at night. If your skin becomes dry, flaky, or irritated when beginning retinol, use it less often at first and keep the Restorative Skin Complex and moisturizer in the routine.

Price and value

The NYK Fashion City product pages could not be loaded directly, so their current listed prices could not be verified. However, comparable authorized retailers list ALASTIN Renewal Retinol 0.5 at about $74 for 1 oz, while the Restorative Skin Complex is commonly sold in a 29 mL / 1 oz size at premium pricing.

Important safety notes

• Patch-test first, particularly if you have sensitive or reactive skin.
• Do not start all three products on the same day. Add one every one to two weeks.
• Use sunscreen daily. Vitamin C and retinol can support anti-aging, but sunscreen remains essential for preventing further photodamage.
• Avoid combining strong exfoliants with retinol initially, as this can cause irritation.
• Consult a dermatologist if you are pregnant or breastfeeding, have rosacea or eczema, or use prescription retinoids.
