Sk-ii Power
SK-II Power products cover three distinct anti-aging lines in 39+ items: R.N.A. Power (essence and cream), Skin Power (cream in three sizes, eye cream, airy cream, essence), and Stem Power (rich cream). These are SK-II's anti-aging and firming-focused products, layering on top of the Facial Treatment Essence Pitera base to address firmness, elasticity, and loss of definition - skin concerns associated with collagen breakdown over time.

SK-II Power Products: R.N.A. Power, Skin Power, and Stem Power Explained
SK-II's Power product family spans 39+ items across three sub-lines - R.N.A. Power, Skin Power, and Stem Power - each addressing skin firmness, elasticity, and definition through different active approaches. All three sit in the upper tier of the SK-II range above everyday moisturising and below the Future Solution LX luxury line. This guide explains what each Power sub-line targets and how the individual products differ.
R.N.A. Power: SK-II's cellular renewal-focused line
R.N.A. Power (Radical New Age) is SK-II's targeted cellular renewal range, developed around the premise that skin's capacity to renew itself slows with age, leading to visible loss of radiance, firmness, and bounce. The R.N.A. Power Essence 50 ml is a concentrated activating serum applied before moisturiser. The R.N.A. Power Radical New Age Cream 80 g is the moisturiser in this sub-line - a rich cream with the full R.N.A. complex. Together, the essence and cream form the R.N.A. Power routine layer on top of the Facial Treatment Essence base.
SK-II Skin Power line: cream, eye, and essence formats
Skin Power is SK-II's premium daily moisturiser line for mature skin. Four formats appear here: Skin Power Cream 50 g (standard size), Skin Power Cream 100 g (value size), Skin Power Cream 80 g Renewal New (updated formula), Skin Power Airy Cream 80 g (lighter texture), Skin Power Essence 30 ml (concentrate serum), and Skin Power Eye Cream 15 g. The Skin Power range targets skin firmness and density loss through advanced peptide and Pitera delivery. The Airy Cream is the lighter-texture version of the Skin Power Cream for humid climates or oilier skin.
Skin Power Cream in 50 g, 80 g Renewal, and 100 g: which size to choose
The 50 g Skin Power Cream is the standard size, providing approximately two to three months of daily use. The 100 g is the value-size that extends supply to four to six months per jar. The 80 g Skin Power Cream Renewal New is the updated formula version - the newest iteration with a refined texture and upgraded active delivery. For new Skin Power buyers, the 50 g is the appropriate trial size. Existing users who know the formula works for them should consider the 100 g for cost efficiency, or the Renewal New for the updated formula.
Skin Power Airy Cream 80 g versus the regular Skin Power Cream
The Skin Power Airy Cream is a lower-density version of the Skin Power formula - lighter, more breathable, and faster-absorbing. It delivers the same SK-II Skin Power actives in a texture more appropriate for oily, combination, or humid-climate skin that finds the regular Skin Power Cream too rich. The regular Skin Power Cream in 50 g or 100 g is better for dry, dry-combination, or cold-climate skin that benefits from richer emolliency. Both layer cleanly over the Facial Treatment Essence.
Skin Power Eye Cream 15 g and RNA Power Eye Cream 15 g: eye-area targeting
Two eye cream formats appear in the Power collection: the Skin Power Eye Cream 15 g and the RNA Power Eye Cream 15 g. Both target the under-eye area for firmness, fine lines, and skin density - concerns that show earlier around the eyes than elsewhere on the face. The 15 g size is standard for a three to four month supply at a twice-daily use of a rice-grain amount. The Skin Power Eye Cream corresponds to the Skin Power moisturiser routine; the RNA Power Eye Cream pairs with the R.N.A. Power cream routine. You do not need both unless you are using both cream lines.
SK-II Skin Power Essence 30 ml: the Skin Power concentrate serum
The Skin Power Essence 30 ml is the serum step in the Skin Power line, applied between the Facial Treatment Essence and the Skin Power moisturiser. It delivers a concentrated Skin Power complex in a lightweight fluid - more targeted than the moisturiser alone. At 30 ml with two to three drops per application, it provides one to two months of evening use. For a complete Skin Power routine: Facial Treatment Essence → Skin Power Essence → Skin Power Eye Cream (eye area) → Skin Power Cream or Airy Cream.
Stem Power Rich Cream 50 ml: the third SK-II Power line
Stem Power is the most premium SK-II Power line, using stem cell-inspired actives to support skin's own renewal and repair capacity. The Rich Cream 50 ml is a dense, nourishing texture suited for dry, mature skin that shows significant firmness loss. It is richer than both the Skin Power Cream and the R.N.A. Power cream. The Stem Power line is the choice for advanced anti-aging users who have already used SK-II's lighter Power options and want a stronger daily repair formula. Apply it as the last moisturiser step in the evening routine.
Which SK-II Power line is right for your skin concerns
Start with skin type and concern severity. Normal skin with early firmness concerns: Skin Power Cream 50 g or Airy Cream. Oily or combination skin: Skin Power Airy Cream 80 g (lighter texture). Significant firmness loss and skin density concerns: R.N.A. Power Essence + Radical New Age Cream. Very dry, mature skin with advanced anti-aging needs: Stem Power Rich Cream 50 ml. For eye-area targeting alongside any cream line, add the matching Eye Cream (Skin Power or RNA Power). All Power lines work on top of the Facial Treatment Essence as the Pitera base.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What is the difference between SK-II R.N.A. Power and Skin Power?
R.N.A. Power targets cellular renewal - stimulating skin's own repair cycle for radiance and visible firmness. Skin Power targets the skin structure itself with peptide and density-building actives for a more direct firmness and bounce effect. R.N.A. Power Essence is the most serum-like product in the family; Skin Power Cream is the primary moisturiser. For concentrated anti-aging treatment, the R.N.A. Power Essence layered under a Skin Power Cream combines both approaches.
Is the Skin Power Cream 100 g better value than the 50 g?
Yes, on a per-gram basis. The 100 g jar provides twice the product volume, typically at a lower price per gram than the 50 g. For users who have confirmed the Skin Power Cream works for their skin, the 100 g is the more economical replenishment choice. The 50 g is better as a first purchase to assess compatibility before committing to the larger size.
What changed in the Skin Power Cream Renewal New 80 g versus the original Skin Power Cream?
The Renewal New is an updated formula with a refined texture and improved active delivery compared to the original Skin Power Cream. SK-II introduced it as a next-generation iteration of the Skin Power moisturiser. The 80 g size is specific to the Renewal New formula - the original comes in 50 g and 100 g. Existing Skin Power users should note the texture may feel slightly different from the original before the formula settles into the skin.
Is the Stem Power Rich Cream 50 ml significantly richer than the Skin Power Cream?
Yes. The Stem Power Rich Cream is the heaviest moisturiser in the SK-II Power range - noticeably denser than both Skin Power Cream variants. It is designed for mature, dry skin with advanced firmness concerns. If you find the regular Skin Power Cream adequate, the Stem Power Rich Cream will likely feel too heavy. For skin that struggles to hold moisture overnight or shows deep texture loss, the Stem Power Rich Cream is the appropriate escalation.
Should I use the Skin Power Eye Cream or the RNA Power Eye Cream?
Match your eye cream to your main face moisturiser. If you use the Skin Power Cream, the Skin Power Eye Cream 15 g is the natural companion. If you use the R.N.A. Power Radical New Age Cream, the RNA Power Eye Cream 15 g matches that routine. Both address eye-area firmness through their respective Power actives. Using both is not necessary - one eye cream matching your main cream is sufficient.
Is the Skin Power Airy Cream 80 g better for humid climates?
Yes. The Airy Cream's lightweight texture is specifically developed for warm, humid conditions where the regular Skin Power Cream can feel too occlusive. In humid climates, the lighter emulsion absorbs faster and does not contribute to the heavy, sealed sensation the regular cream produces in heat. The Skin Power Airy Cream delivers the same actives in a gel-cream texture that is more comfortable when ambient humidity is high.
Do I need the Skin Power Essence 30 ml if I already use Skin Power Cream?
The Skin Power Essence is an optional add-on, not a required step. The cream delivers the Skin Power actives on its own. The essence adds a concentrated serum layer that delivers a higher payload of actives before the cream seals them in. For users wanting the most intensive Skin Power routine, the essence + cream combination is more effective than cream alone. For a simpler routine, the cream alone is sufficient.
Are these SK-II Power products authentic Japanese imports?
Yes. All SK-II Power products - R.N.A. Power, Skin Power, and Stem Power - in this collection are authentic SK-II Japanese-market products imported from Japan. SK-II is a Japanese brand and the products here are sourced from Japanese-market distribution with original formula specifications. Labeling includes Japanese text alongside English product names.
