Absolutely, you've captured the rationale perfectly. Starting with a lower concentration of tretinoin allows the skin to build tolerance to the medication gradually, minimizing the likelihood of severe irritation and side effects that can occur when using higher concentrations from the outset.

Tretinoin works by increasing the turnover of skin cells, promoting the shedding of dead skin cells, and stimulating the growth of new, healthier skin cells. This process can cause the skin to become dry, red, and peel initially as the skin adjusts to the medication. However, with continued use, the skin's barrier function can strengthen, and the irritation tends to diminish.

By initiating treatment with a lower concentration, the skin has time to Tretinoin cream 0.1% adapt and develop a better tolerance to the effects of tretinoin. This gradual introduction helps to:

1. Reduce irritation: Starting with a lower concentration allows the skin to get accustomed to the effects of tretinoin without overwhelming it with a high dose immediately.
2. Enhance compliance: The lower concentration may be more comfortable for patients to use regularly, as it is associated with less severe side effects.
3. Monitor skin response: Dermatologists can closely monitor the patient's skin response during the initial stages of treatment and adjust the concentration or frequency as needed.
4. Minimize potential setbacks: Introducing tretinoin gently can help prevent severe peeling, redness, or irritation, which might otherwise lead some individuals to discontinue treatment prematurely.

Once the skin has successfully adapted to the lower concentration, the dermatologist may consider increasing the strength if necessary, based on the patient's specific skin condition and response to treatment.

Remember that every individual's skin is different, and the ideal tretinoin concentration and application frequency can vary from person to person. Dermatologists are well-equipped to assess the patient's skin type, concerns, and medical history, allowing them to tailor the treatment plan to achieve the best possible outcomes with minimal side effects. Regular follow-ups with the dermatologist are crucial to ensure the treatment is effective and well-tolerated.
