Whether you are stopping deliberately, taking a break, or just ran out, here is what to expect and what is worth knowing before you decide.
There is no withdrawal
Starting with the reassurance, because it is the most common worry. Glutathione, collagen and grape seed extract do not produce dependency or a withdrawal syndrome. You can stop at any point without tapering.
What you will not get is a sudden reversal. Nothing dramatic happens in the first week.
What actually happens, and when
Weeks 1 to 4: generally nothing visible. Whatever effect the supplement was having persists while existing skin cells complete their cycle.
Weeks 4 to 12: if the supplement was contributing, this is where the contribution gradually stops appearing in newly surfaced skin. Any change is slow and cumulative rather than a drop-off.
Beyond three months: your skin returns to the state it would have been in given your sun exposure, genetics, age and topical routine.
The key point is that this mirrors the timeline going in. It took three months to assess whether it worked, and it takes a comparable period to see the absence.
What is not caused by stopping
People frequently attribute changes to stopping that have other causes.
- A breakout the week after stopping is almost certainly unrelated. The timeline does not work.
- Sudden darkening is far more likely to be a change in sun exposure, or a season, than the absence of a capsule.
- Rebound pigmentation, where skin becomes darker than it was originally, is a real phenomenon with certain unregulated topical products containing steroids or hydroquinone. It is not something oral antioxidants do. If you are seeing genuine rebound darkening, look at what you were applying rather than what you were swallowing.
Reasons to stop that are worth respecting
- You gave it a fair trial and saw nothing. Three to six months of consistent use with sunscreen and photographs, and no change, is a legitimate result. Continuing to buy something that is not working for you is not loyalty, it is sunk cost.
- Cost. Entirely reasonable. If budget is the constraint, sunscreen and a decent moisturiser deliver more per unit of spend than any supplement, and that is the honest ranking.
- You are pregnant or planning to be. Stop, and see our guide on this.
- You are starting a new prescription. Tell your doctor what you were taking.
- Persistent side effects beyond the first fortnight.
Before you stop, rule out the obvious
If you are stopping because it did not work, it is worth checking that it had a fair chance. Inconsistent dosing, no sunscreen, and judging by memory rather than photographs are the three most common reasons a supplement appears to do nothing. Our guide on why glutathione may not be working covers the full list, and several items on it are fixable in a week.
If you are pausing rather than quitting
Gaps of a few weeks are not a problem, and there is no need to restart at a lower dose. Resume the normal serving.
What a gap does cost you is assessment time. If you were three months into evaluating something and stopped for six weeks, you are not three months in any more. Multi-bottle sets exist largely to prevent unplanned gaps, and current tiers are in the bundle collection.
What to keep doing
If you stop everything else, keep these:
- Daily sunscreen. The highest-return item in any routine by a wide margin.
- Moisturiser.
- Gentle cleansing.
A person who stops all supplements and keeps daily sun protection will, over a year, generally have better skin than a person who does the reverse. That is worth saying plainly even though we sell the supplements.
If you restart later
Treat it as starting fresh. Photograph a new baseline, give it three months, and do not compare against how you remember your skin looking previously, because that comparison is unreliable in both directions.
