Uneven Skin Tone After Using Whitening Agents

It appears you are experiencing uneven white patches on your skin after mixing ODA-White Plus and Activated Resorcinol into your Olay cream. This is understandably concerning.

Based on the concentrations you used:

• ODA-White Plus: 1.5g in 50g cream is approximately 2.9%.
• Activated Resorcinol: 2.5g in 50g cream is approximately 4.8%.

While ODA-White Plus was used within or slightly above its recommended range (1-3%), the concentration of Activated Resorcinol you used (around 4.8%) is significantly higher than the recommended maximum of 1.0% for leave-on products like creams.

Activated Resorcinol is a very potent whitening agent. Using it at concentrations much higher than recommended can lead to skin irritation or unexpected pigmentation responses, such as the uneven white patches you observed. Even if the total percentage of actives seems within a general limit, exceeding the specific recommended usage rate for a potent ingredient like Activated Resorcinol is likely the cause of this reaction.

Stopping the use of the mixture, as you have done, is the correct immediate step.

Your skin should gradually return to its normal tone over time as your skin cells naturally regenerate and the effects of the ingredients fade. The recovery time can vary depending on the individual and the severity of the reaction.

If you wish to continue with skin whitening, you might consider using alternative ingredients that may be less prone to causing this type of reaction, such as Vitamin C derivatives. Options like Ascorbyl Tetraisopalmitate or Sodium Ascorbyl Phosphate are often well-tolerated. Always start with a low concentration and perform a patch test on a small area before applying to larger areas.

Remember to protect your skin from UV exposure, as sunlight can affect pigmentation and skin sensitivity.
