The INKEY List Advanced Retinal Serum - 15ml

Retinaldehyde (retinal) is a direct precursor to retinoic acid, the active form of Vitamin A in the skin. It is generally considered more potent and faster-acting than retinol, while often being better tolerated than prescription retinoids.

Begin by using it 2-3 nights per week. As your skin adjusts, you can gradually increase the frequency to nightly use. Listen to your skin and adjust as needed.

It's best to introduce retinoids slowly. Avoid using other potent actives like AHAs, BHAs, or Vitamin C in the same routine initially. Once your skin is accustomed, you may be able to incorporate them at different times (e.g., Vitamin C in the morning, retinal at night).

While formulated to be effective, all retinoids have the potential to cause irritation. Start slowly, moisturize well, and consider patch testing first. If you have very sensitive skin, consult a dermatologist before use.

Results from retinoids vary per individual but typically appear after 4-12 weeks of consistent use. Improvements in texture and tone may be noticeable first, followed by reductions in fine lines and wrinkles.

Skin purging is a temporary increase in breakouts that can occur when starting retinoids, as they speed up cell turnover. It usually subsides within a few weeks. Continue with consistent use and good hydration, but if it's severe or prolonged, consult a professional.

No, this serum should only be used at night. Retinoids increase sun sensitivity, so it is crucial to use a broad-spectrum sunscreen every morning.

This is known as retinization. Reduce application frequency to 1-2 times per week. Ensure you are using a good moisturizer and apply the serum to dry skin. If irritation persists, discontinue use and consult a dermatologist.

Ensure the product is stored correctly (away from light and heat). Verify you are applying a sufficient amount (pea-sized) and that the product has not expired. Consistency is key for retinoids.

This can be normal for some serum formulations. Allow it to absorb fully before applying moisturizer. If it remains uncomfortably sticky, try using a slightly smaller amount or ensure your skin is fully dry before application.
