Retinol vs Retinal for Beginners: How to Start Vitamin A the Korean Way
Retinal converts to retinoic acid in one step, so it works faster than retinol; bakuchiol is the gentle plant route. How to start vitamin A the Korean way.
Retinol and retinal are two forms of vitamin A — the most proven ingredient family in anti-aging skincare — and the difference between them is one step. Skin can only use vitamin A as retinoic acid: retinol needs two conversions to get there, retinal (retinaldehyde) needs one, which is why retinal shows results sooner at a comparable level of comfort. Bakuchiol, the plant-derived alternative, is the lane for skin that tolerates neither. The Korean way to start any of them is unhurried — two evenings a week, buffered with moisturizer, sunscreen every morning — and September, when the fierce summer sun finally softens, is exactly the right time to begin.
- •Retinal (retinaldehyde) converts to retinoic acid in one step — retinol needs two, so retinal shows results sooner.
- •Start low and slow: two evenings a week for the first weeks, then build up gradually as skin adjusts.
- •Buffering — applying moisturizer before or after — softens the landing without cancelling the effect.
- •SPF the next morning is non-negotiable: vitamin A makes skin more sun-sensitive while it renews.
- •Bakuchiol is the plant-based alternative for sensitive skin — Eqqualberry's Plumping Serum uses it at 0.5%.
Retinol, retinal, bakuchiol: one family, three speeds
All vitamin A derivatives end up in the same place — retinoic acid, the form that tells skin to renew faster, smooth fine lines and refine texture. What differs is the distance. Retinol is the classic two-step route: reliable, well studied, slightly slower. Retinal sits one conversion from the destination, which is why K-beauty has embraced it as the faster ingredient that stays livable. Korean formulation adds its own trick: liposome encapsulation, as in Seoul 1988's line, wraps retinal in a shell that releases it gradually — less irritation, same direction. And bakuchiol, extracted from the babchi plant, delivers a gentler smoothing-and-firming effect without belonging to the vitamin A family at all — which is exactly its charm for reactive skin.
Why autumn is the season to start
Vitamin A makes renewing skin more sensitive to the sun, which is why the classic advice — start retinoids after summer — exists. In Israel, where summer UV is relentless, September is when that advice finally fits the weather: shorter days, softer sun, and months of mild evenings ahead for skin to adjust in. You still wear sunscreen every single morning — that part never becomes optional — but starting now means your skin builds tolerance through the forgiving season and meets next summer already settled.
Choosing your first vitamin A
The friendliest first step is a booster you control drop by drop. Celimax's Vita-A Retinal Shot Booster delivers 0.1% retinal in a 15ml shot with niacinamide and panthenol to keep skin balanced — add a few drops to your evening cream, or use it alone once skin is comfortable; it is one of Skin101's best-selling serums for a reason. For a fuller-strength serum, Seoul 1988's Serum Retinal Liposome 2% - BLACK GINSENG uses that gradual liposome release on a black ginseng base. Prefer the classic route? Celimax's Vita-A Retinol Shot Tightening Serum works on pores, lines and elasticity with retinol kept calm by panthenol and allantoin, and COSRX's The Retinol 0.1 Cream introduces retinol at a beginner-friendly 0.1% in a cushioning cream base.

The low-and-slow protocol
Evenings only, a pea-sized amount for the whole face, on dry skin. Start two nights a week; after a few comfortable weeks, move to every other night, and only then consider nightly use. Buffering is the beginner's best friend — moisturizer first, vitamin A on top, or the reverse — it slows delivery without cancelling it. Then learn the difference between purging and irritation: purging is breakouts in your usual congestion areas as renewal speeds up, and it settles within a few weeks; irritation is stinging, redness and flaking everywhere, and it means slow down — fewer nights, more buffering. And the next morning, sunscreen. Always.
The gentle lane: liposome cream and bakuchiol
If your skin runs sensitive, start softer. Seoul 1988's Cream Retinal Liposome 1% - FERMENTED RICE puts a gentler retinal dose in a comfortable daily cream, the liposomes pacing the release while fermented rice soothes — serious ingredients in the least demanding format. And for skin that vitamin A simply does not agree with, Eqqualberry's Bakuchiol Plumping Serum takes the plant route at 0.5%, cushioned with ceramides, squalane and shea butter: plumper, smoother-looking skin with none of the adjustment period.

Original or fake? How to tell before you buy
The K-beauty boom has a side effect: online marketplaces are full of counterfeit and grey-market products — lookalikes that may be expired, diluted or stored for months in a hot warehouse. Skin101 works with the brands' official importer in Israel, and every product we ship carries the importer's stamp and the official usage instructions on its packaging. That small label is your guarantee of the real formula; if it's missing, you're not buying the original.
Frequently Asked Questions
What is the difference between retinol and retinal?+
Both are vitamin A derivatives that skin must convert to retinoic acid to use. Retinol needs two conversion steps; retinal (retinaldehyde) needs one, so it works noticeably faster at a comparable comfort level. Korean formulas like Seoul 1988's liposomal retinal release it gradually to keep irritation low.
Is my skin purging or irritated?+
Purging is breakouts concentrated in your usual congestion areas as skin renewal speeds up, and it settles within a few weeks of consistent use. Irritation is stinging, redness, dryness and flaking across the face — a signal to slow down: fewer nights per week and more buffering with moisturizer.
Can I use retinal in summer?+
Yes — vitamin A is used at night, so summer use is fine as long as sunscreen is worn strictly every morning. Starting in autumn is simply easier: softer sun gives skin a forgiving season to build tolerance before the next high-UV summer.
Where can I buy retinal serums in Israel?+
