If you're weighing la prairie platinum rare vs la mer genaissance for women over 70, the short answer is this: La Prairie Platinum Rare leads on visible firming, jawline definition, and architectural lift, while La Mer Genaissance leads on deep cushioned hydration, comfort, and softening the look of papery, thinned skin. Both are credible investments in the over-70 category, but they solve different problems. Skin that has lost structural support and contour will respond better to Platinum Rare's platinum-peptide complex. Skin that feels parched, sensitised, or fragile will feel more at home in Genaissance's Miracle Broth-rich emulsion.
Why this comparison matters more after 70
Skin biology shifts meaningfully in the eighth decade. Collagen production has slowed for decades, but by 70 the dermal matrix has also lost elastin density, vascular support, and lipid reserves. The result is the thinned, crepey, often translucent texture so familiar to women in this age group, alongside slackening along the jaw, deeper nasolabial folds, and a dullness that no amount of standard moisturiser seems to lift. A luxury anti-aging cream at this stage is not vanity—it is a functional tool for skin comfort, barrier integrity, and confidence.
That is the lens I use when evaluating la prairie platinum rare vs la mer genaissance for women over 70. Marketing claims aside, what matters is how each formula behaves on mature, often dehydrated, sometimes reactive skin—and which one earns its considerable price.
La Prairie Platinum Rare: the firming architect
Platinum Rare Haute-Rejuvenation Cream is built around La Prairie's Exclusive Platinum Peptide. The formula targets what the brand calls the skin's "electrical balance," but in practical use it is best understood as a firming, contouring cream. After four to six weeks, women over 70 typically describe a tighter feel along the jaw, a more defined cheek apple, and a brighter overall tone. Texture is rich but not occlusive—closer to a whipped silk than the dense cushion you get from La Mer.
Where Platinum Rare excels is structural support. Where it can fall short is comfort on truly parched skin, which often needs an additional hydrating step layered underneath. That is why a treatment essence or hyaluronic serum is essentially mandatory in a Platinum Rare routine for older skin.
La Mer Genaissance: the cushioned restorer
Genaissance de la Mer The Infused Lotion and The Cream sit at the top of the La Mer hierarchy. They lean on a concentrated form of Miracle Broth plus the brand's Lifting Ferment for a heavier, more enveloping cushion than the standard Crème de la Mer. For women over 70 whose primary complaint is tightness, dryness, sensitivity, or a feeling that their skin has become fragile, Genaissance delivers a noticeable softening within a week.
What Genaissance does not do as dramatically is sculpt or lift. You will not see the same jawline definition you can get from Platinum Rare. What you will see is a plumper, more rested, less papery appearance—often with reduced redness and a softer light reflection. For many women this trade-off is exactly right.
Side-by-side comparison
| Feature | La Prairie Platinum Rare | La Mer Genaissance |
|---|---|---|
| Primary strength | Firming, contouring, jawline definition | Deep hydration, comfort, softening crepe |
| Texture | Whipped silk, rich but airy | Cushioned, balm-like, enveloping |
| Hero technology | Exclusive Platinum Peptide | Concentrated Miracle Broth + Lifting Ferment |
| Best for skin type at 70+ | Slackening, loss of contour, dullness | Thinned, dry, sensitive, papery skin |
| Layering needs | Pair with hydrating essence underneath | Largely self-sufficient; press in, don't rub |
| Visible results timeline | 4–6 weeks for firmness shift | 1–2 weeks for comfort, longer for texture |
| Fragrance | Light signature scent | Subtle marine/floral |
| Best paired with | A platinum-tier serum or caviar essence | A nourishing oil or treatment lotion |
If you only buy one and you are over 70 with combination concerns, my honest recommendation is this: choose Platinum Rare if your mirror reflection bothers you more than how your skin feels, and choose Genaissance if how your skin feels bothers you more than how it looks. Most readers in this age group will, in practice, alternate between them or use them at different points in the year.
Available picks that work in the same league
Below are luxury creams you can buy today that align with the goals discussed above. They are not substitutes for Platinum Rare or Genaissance, but each addresses a specific need that women over 70 commonly raise.
La Prairie Skin Caviar Liquid Lift
This is the most direct entry point into the La Prairie firming philosophy. The Caviar Premier complex delivers visible lift along the jaw and cheek area within a few weeks, and the texture suits older skin that doesn't tolerate heavy occlusives. Use it under Platinum Rare for layered firmness or on its own as a daily lifting treatment. View Skin Caviar Liquid Lift on Amazon.
La Mer Moisturizing Cream (the original Crème de la Mer)
If you are curious about the La Mer house but not ready to commit to Genaissance pricing, the original Moisturizing Cream remains the brand's most studied formula. It is denser than Genaissance and best warmed between fingertips before pressing onto skin. For women over 70 with dry or barrier-compromised skin, it is one of the most reliably comforting luxury creams on the market. View La Mer Moisturizing Cream on Amazon.
Augustinus Bader The Cream
Bader's TFC8 technology takes a different scientific approach—cellular signalling rather than peptide loading. The Cream is lightweight enough for layering and tends to suit women over 70 who find both Platinum Rare and Genaissance too rich for daytime. Expect gradual improvements in tone, texture, and reactivity over eight to twelve weeks. View Augustinus Bader The Cream on Amazon.
Estée Lauder Re-Nutriv Lightweight Face Cream
Re-Nutriv has quietly served the over-70 demographic for decades. The lightweight version is an underrated choice for mature skin that wants the prestige finish without a heavy balm feel. It pairs particularly well with a richer night cream. View Estée Lauder Re-Nutriv on Amazon.
La Prairie Skin Caviar Essence-in-Lotion
This is the layer most women miss when comparing la prairie platinum rare vs la mer genaissance for women over 70. A pre-serum essence dramatically improves how either rich cream sits on thinned skin. The Caviar Essence-in-Lotion preps the surface so that the cream you choose can settle in without dragging or pilling. View Skin Caviar Essence-in-Lotion on Amazon.
How to build a routine at 70 around either cream
Whichever direction you choose, the routine principles for skin in this decade are consistent: avoid stripping cleansers, hydrate before you treat, layer thin to thick, and never apply a luxury cream to bone-dry skin. The richest cream in the world will sit on top of a dehydrated surface and do nothing measurable. Instead, dampen skin lightly with a treatment lotion or essence, press the cream in with warm palms, and follow with an eye cream and SPF in the morning.

Honest verdict for women over 70
The most candid framing of la prairie platinum rare vs la mer genaissance for women over 70 is this: La Prairie is the choice when you want to see a change in the mirror. La Mer is the choice when you want to feel a change in your skin. If budget allows both, use Platinum Rare in the morning for daytime lift and Genaissance at night for restoration. If budget allows one, choose the cream that solves the concern you wake up thinking about. Either way, the supporting routine—cleanser, essence, serum, eye cream, SPF—matters more than most marketing copy will admit.
Frequently Asked Questions
Is La Prairie Platinum Rare worth it for skin over 70?
Yes, if your primary concern is loss of firmness and contour. The platinum peptide complex is best in class for visible lift at this age. It is less worthwhile if your skin is mainly dry or sensitive, in which case Genaissance, the original Crème de la Mer, or Augustinus Bader The Cream will likely satisfy you more.
Is La Mer Genaissance too rich for women over 70 with combination skin?
Rarely. Most combination skin at 70 has shifted toward dry dominance regardless of how the T-zone behaved decades ago. Genaissance suits this transition well. If you still experience midday shine, use Genaissance only at night and a lighter cream like Re-Nutriv Lightweight or Augustinus Bader in the morning.
Which cream is better for crepey skin on the neck and décolleté?
Genaissance has the edge for crepey skin because its Miracle Broth-rich texture cushions and softens the look of thinned tissue more dramatically. Platinum Rare improves firmness over time but does not soften crepe as immediately. For best results, extend either cream downward and upward in firm, sweeping motions and consider layering a peptide serum underneath.
How long before I see results with Platinum Rare or Genaissance at this age?
Comfort and hydration improvements from Genaissance are usually visible within 7 to 14 days. Firming and contouring results from Platinum Rare take 4 to 6 weeks of consistent twice-daily use. Skin over 70 turns over more slowly, so patience is genuinely required—abandoning a luxury cream at the three-week mark is the single most common mistake in this category.
Can I use both La Prairie Platinum Rare and La Mer Genaissance together?
Yes, and many women over 70 do. The most successful pairing is Platinum Rare in the morning for daytime firmness and Genaissance at night for restorative hydration. Avoid layering them in the same routine—the textures are heavy enough that they will compete rather than complement on mature skin.
What if my budget doesn't stretch to either Platinum Rare or Genaissance?
Augustinus Bader The Cream and Estée Lauder Re-Nutriv Lightweight both deliver meaningful results for women over 70 at lower price points. Pair either with a quality treatment essence and a peptide eye cream, and you'll close most of the gap to the top-tier formulas. The supporting routine often matters more than the marquee jar.
Do I still need SPF if I'm using a luxury anti-aging cream at 70?
Absolutely—arguably more than at any other age. UV continues to degrade what little structural support remains in the dermis and accelerates the appearance of age spots, which become harder to fade after 70. Apply a mineral SPF 30 or higher over your morning cream every day, regardless of weather or whether you plan to leave the house.
