I am 23. How to manage skin redness after acne treatment?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 23 years old and weigh 160 pounds. I had pimples and dark spots on my face, so I visited a doctor who prescribed Tretinoin 20 mg (Isotretinoin) and Isotin 10 mg (Isotretinoin) to be taken for one month. He also advised me to use Skintex face wash. Along with that, I used Robex sunscreen, Lumexa cream and serum, and Metafil moisturizer.

I followed this treatment for seven days, but now my skin has become red, darker, and new dark spots have appeared. What could be the reason for this reaction?

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

It sounds like the skin is having a strong reaction to the treatment, and it is understandable to feel worried, given how uncomfortable and discouraging this can be. The redness, darkening, and appearance of new dark spots are most likely signs of irritation or sensitivity, which are common side effects when starting retinoid-based treatments such as Tretinoin. Tretinoin contains (vitamin A derivative), which increases skin cell turnover. While it is very effective for acne and pigmentation, it can initially cause redness, peeling, dryness, and temporary worsening of dark spots due to inflammation, especially if used too frequently or in combination with other active products.

Using multiple products at the same time, such as Lumexa cream and serum, which often contain brightening or exfoliating ingredients, can further irritate the skin barrier when combined with Tretinoin (vitamin A derivative). This irritation can trigger post-inflammatory hyperpigmentation (PIH), which appears as new dark spots. Sun exposure without adequate protection can also worsen this reaction, even if sunscreen is used, because Tretinoin (vitamin A derivative) makes the skin much more sensitive to sunlight.

At this stage, it is best to stop using Tretigen (Tretinoin) and other active creams until the redness and irritation subside. Focus on soothing and repairing the skin barrier with a gentle, fragrance-free cleanser such as Metafil (emollient-based cleanser) and a thick Moisturizer (emollient). Avoid scrubbing, exfoliating, or applying any new creams for several days. Continue using a high sun protection factor (SPF) sunscreen, applying it every morning and reapplying if outdoors. Once the skin has completely calmed down, the doctor can guide on restarting Tretinoin (vitamin A derivative) gradually, such as using it every third night initially or switching to a milder formulation.

Following the doctor’s advice was the right step, but every individual’s skin reacts differently, and sometimes treatment needs adjustment depending on tolerance. It is advisable to contact the dermatologist soon to show the recent changes, as they can modify the regimen safely and help prevent further irritation. With proper care and adjustments, the skin should heal and improve over time.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
