FAQ
What makes COSRX The Retinol 0.5 Oil different from other Korean retinol products?

COSRX The Retinol 0.5 Oil uses 0.5% stabilized pure retinol, not derivatives, combined with Super Vitamin E (tocotrienol) and squalane for improved elasticity and hydration. This formula delivers high-strength care for firmer, youthful-looking skin while remaining barrier-safe and suitable for acne-prone or sensitive skin types that have built retinol tolerance.

How long does it take to see visible results from COSRX The Retinol 0.5 Oil?

Clinical studies show visible skin improvement in as little as 14 days, with measurable wrinkle reduction and elasticity increase within 4 weeks. Forehead wrinkles decreased by 22%, and eye area lines improved by 17%, based on Dermacosmetic Skin Science Laboratory testing.

Is cosrx the retinol 0.5 oil suitable for acne-prone skin?

Yes, it’s suitable for acne-prone skin. The formula includes squalane and vitamin E to help reduce dryness and irritation while retinol works on the appearance of clogged pores and uneven texture.

How should I introduce COSRX The Retinol 0.5 Oil into my routine safely?

Use 2–3 times a week at night for the first 2 weeks, applying 1–2 drops only to areas of concern (or mix with your moisturizer for a gentler start). From Week 3, you may use it every other night and spread a thin layer over the entire face if your skin feels comfortable. Always follow with sunscreen during the day.

What benefits can I expect from consistent use of COSRX The Retinol 0.5 Oil?

With continued use, the skin becomes firmer, smoother, and more radiant. The 0.5% pure retinol boosts collagen production, softens fine lines, and improves uneven tone while vitamin E and squalane strengthen the skin barrier.

Can COSRX The Retinol 0.5 Oil be layered with other active ingredients?

It can be used with barrier-supporting or hydrating products, but avoid combining with exfoliating acids (AHAs, BHAs) or high-concentration vitamin C in the same routine. For best results, use retinol at night and pair with SPF during the day to protect renewed skin.

Who should use COSRX The Retinol 0.5 Oil - beginners or advanced users?

This oil is designed for intermediate to experienced retinol users who are ready for a higher strength (0.5%) formula. Beginners should start with COSRX The Retinol 0.1 Cream or 0.3 Cream to build tolerance before advancing to this concentrated oil.
