Yes, Dr. Rajani's products are formulated for all skin types, including normal, dry, combination, and oily skin. If you have very sensitive skin or specific skin concerns, we recommend consulting with your physician or contacting our team for personalized guidance.

Our Retinol A Serum is designed to be a great starter retinol because it includes three forms of retinol plus avocado oil for added support. We recommend starting once or twice weekly and increasing gradually as your skin builds tolerance.

Yes, but Retinol Serum and AHA Firming Cream are best used on different days or alternate nights to help reduce irritation. Many people use retinol one night and AHA the next. If your skin is more sensitive, start with each product 1–2 times per week and increase slowly as tolerated. If using either product in the morning, always apply broad-spectrum SPF.

Some individuals with rosacea tolerate AHA well, but results can vary. Because rosacea-prone skin is more sensitive, we recommend consulting your physician before use and starting slowly to assess tolerance.

You can start by using AHA Firming Cream 1–2 times per week in the evening, on nights you are not using Anteage. If layering, apply Anteage first, wait about 5 minutes, then apply the AHA. Adjust frequency based on your skin’s tolerance.

AHA Firming Cream is not recommended for the under-eye area. The skin here is thinner and more delicate, making it more prone to irritation from exfoliating acids.

For concerns like fine lines, crepey texture, and dark circles, we recommend using products specifically formulated for the eye area, such as the DEJ Eye Cream. Devices like the PlasmaGLO LED Duo can also help support under-eye rejuvenation.

Most people notice smoother texture and increased brightness within 1–2 weeks. More visible improvements—such as enhanced tone, clarity, and reduction in fine lines—typically develop over 4–6 weeks with consistent use. Daily SPF and proper hydration will help optimize results.
