What This Serum Does for Your Skin
PURITO SEOUL Retinol Retinal 2000 NAD+ Serum brings together two forms of vitamin A in one bottle. Retinol works gradually to support smoother, firmer looking skin over time. Retinal moves faster, helping skin renew itself and refine visible texture. Together, they target the signs that skin is starting to look tired, like fine lines and rough patches.
NAD+ is the ingredient that sets this serum apart from a standard retinoid. It supports your skin's own renewal processes, helping cells function the way they did when skin felt more resilient. At 100 parts per million, it works alongside the retinoids rather than instead of them.
This is not a gentle vitamin C or a light hydrating serum. It is a focused retinoid treatment built for people who want visible change in firmness and texture. The formula still leans on soothing ingredients, so the strength does not have to mean discomfort.
Used consistently at night, this serum becomes the active step in your routine. It sits underneath a moisturiser and is always followed by sunscreen the next day, since retinoids increase sun sensitivity.
The Key Ingredients Inside
Retinol at 1,000 parts per million supports firmer looking skin with steady use over time. Retinal, also at 1,000 parts per million, speeds up cell turnover so rough texture starts to feel smoother. Using both together gives you retinol's steady benefits and retinal's quicker renewal in one step.
Nicotinamide adenine dinucleotide, or NAD+, supports the energy your skin cells need to repair themselves. This shows up over time as a more resilient, even complexion. Niacinamide works alongside it to reinforce your skin's barrier and calm visible redness. Adenosine adds a further layer of support for skin's natural elasticity.
Because retinoids can feel intense on their own, PURITO SEOUL balanced the formula with centella asiatica extract. This soothes reactive skin and eases discomfort. Ceramide NP reinforces the barrier from within, helping skin hold onto moisture while the actives do their work. This combination is what makes a strong retinoid serum feel wearable for skin that is still adjusting.
How Your Skin Responds Over Time
Retinoids work by speeding up how quickly skin cells turn over and renew. This is why most people start slowly rather than using a strong serum every night straight away. PURITO SEOUL recommends beginning with two to three nights a week.
As your skin builds tolerance, you can increase how often you use it. Some people notice mild flaking or tightness at first, which is a normal part of skin adjusting to retinoids. This usually settles as your skin gets used to the actives.
With regular use, skin tends to look smoother and feel firmer to the touch. Fine lines can appear less noticeable as texture evens out. The formula includes centella asiatica and ceramide NP. This helps the adjustment period feel calmer than with a plain retinol serum.
Consistency matters more than speed here. A retinoid serum works best as a long-term habit, not a quick fix you use for a week and stop. Sticking with the routine, alongside daily sunscreen, is what lets you see the full benefit.
How to Layer It in Your Routine
This serum is a nighttime-only step, since retinoids increase your skin's sensitivity to sunlight. Use it after cleansing and toning, while your skin is clean and dry. Shake the bottle well before each use to combine the layered formula.
Dispense one to two drops into your palm or straight onto your fingertips. Smooth it over your face, avoiding the eye area and any broken skin. A little goes a long way with a formula this concentrated.
Follow with a moisturiser to lock in hydration and support the barrier while the retinoids work. If your skin feels tight or dry, applying a richer cream on top can help. Some people prefer to buffer the serum by applying moisturiser first, then the serum on top.
The next morning, sunscreen is not optional. Retinoids make skin more reactive to UV light, so daily SPF protects the results you are working towards. Skip a vitamin C or exfoliating acid on the same night to avoid overloading your skin. Pair this serum with barrier-supporting products rather than other strong actives.
Who This Serum Is For
This serum suits anyone who wants a visible step up from a gentle anti-aging routine. If fine lines, loss of firmness, or uneven texture are starting to bother you, this is built for that stage. It works well for people who have used retinol before and want a stronger option.
It also suits retinoid beginners who want extra comfort built into the formula. The soothing ingredients mean you are not choosing between strength and comfort. You can ease in slowly and build up as your skin adjusts.
This is a vegan, cruelty-free, and fragrance-free formula, so it fits a routine that avoids synthetic scent. This is not the right choice if you are new to skincare altogether. It also is not ideal if your skin barrier feels compromised right now. In that case, start with gentler basics first and come back to retinoids later.
If a gentle vitamin C serum no longer feels like enough, this is where you go next. Two retinoids and NAD+ work together so your skin gets steady, visible support without feeling stripped or reactive. Start slow, stay consistent, and let your skin set the pace.
