Anua Starter Kit -

It's generally recommended to introduce the Niacinamide 10% + TXA 4% Serum gradually. If you are using other strong actives like retinoids or AHAs/BHAs, consider alternating them on different days or using them at different times of the day (e.g., serum in the AM, other actives in the PM) to avoid irritation. Always patch test.

Yes, the kit is suitable for oily skin. The cleansing oil effectively removes excess sebum and impurities without stripping, the foam contains BHA to help control oil and exfoliate, and the sunscreen is lightweight and non-greasy.

The Niacinamide 10% + TXA 4% Serum can be used both in the morning and evening. However, since it targets dark spots and promotes a brighter complexion, using it in the morning routine before sunscreen is beneficial for added protection and treatment throughout the day. If you experience any sensitivity, start with evening use.

Results can vary depending on individual skin concerns and consistency of use. Typically, noticeable improvements in dark spots and skin tone with niacinamide and tranexamic acid can be observed within 4-8 weeks of consistent daily use.

The Zero-Cast Moisturising Suncream does provide hydration. For normal to oily skin types, it might be sufficient on its own. However, if you have dry or very dry skin, you may wish to layer your preferred moisturizer underneath the sunscreen for additional hydration.

The products are generally formulated to be gentle, especially the cleansing oil and sunscreen. However, the Niacinamide 10% + TXA 4% Serum contains high concentrations of active ingredients. Sensitive skin types should perform a patch test first and introduce the serum slowly, reducing frequency if any irritation occurs.

Ensure you are rinsing thoroughly. You can also follow the cleansing oil immediately with the foam, or use slightly less foam if your skin is particularly dry. If dryness persists, consider adding a dedicated moisturizer at night.

This can be a normal reaction to active ingredients like niacinamide and tranexamic acid. Reduce the frequency of application (e.g., every other day) and use only 1-2 drops. Gradually increase usage as your skin adjusts. If irritation continues, discontinue use.

Ensure you are applying a thin, even layer and allowing it to absorb fully for a minute or two before applying makeup. If a white cast persists, you may be applying too much product. Try a smaller amount.

Ensure you are applying the oil to dry skin and massaging it thoroughly, especially over areas with heavy makeup or SPF. For very stubborn makeup, consider a dedicated eye makeup remover first.
