My skin no longer stings. Can I restart all my actives?

I would not restart everything together. Check whether washing and moisturizing feel comfortable and whether redness or tightness is still present. Recovery is better judged by overall comfort, redness, heat, and post-wash tightness than by the absence of one symptom alone.

No stinging does not always mean full recovery

The disappearance of stinging is a good sign, but I also look for normal comfort after cleansing, less reactive redness or heat, and moisturizer feeling normal again.

Bring actives back one at a time

When the skin looks ready, bring back one active at a time rather than returning immediately to the full old routine. That gives you much clearer feedback.
